Coffee’s Environmental Footprint Should Be Harder to Swallow Than Dubious Cancer Claims

Coffee is not only my favorite drink, it’s a necessity (I get headaches from caffeine withdrawal). Even after a California judge decided this week that coffee should come with a cancer warning, my immediate response was to take another sip.

That’s because coffee does not cause cancer, top scientists have concluded. In fact, numerous studies show that coffee has incredible health benefits, from lowering diabetes risk and, yes, protection against cancer.

It’s important to note that Los Angeles Superior Court Judge Elihu Berle’s decision Wednesday was not to establish a coffee-cancer link. Rather, the outcome of the long-brewing lawsuit fell under California’s Proposition 65, which requires businesses to warn people of exposure to roughly 900 chemicals known to cause cancer or birth defects.

Roasted coffee beans happen to contain a known carcinogen called acrylamide, a chemical also found in fried potatoes and burnt toast. While very high doses of acrylamide can increase the risk of cancer in lab animals, it is not yet clear if it affects cancer risk in humans.

Because of the ruling, about 90 coffee roasters, retailers and distributors, including Whole Foods, Kraft and Green Mountain Coffee Roasters, might have to post warning labels on their coffee, the Los Angeles Times reported.

The National Coffee Association, whose members include Starbucks and Dunkin’ Donuts, plans to fight this decision and is “currently considering all of its options, including potential appeals and further legal actions.”

However, there are certain labels that these businesses should consistently adopt for human health and for the planet’s health, including “organic,” “Fair Trade Certified” and “shade-grown beans.”

Ultimately, the environmental footprint of our daily brew should be harder to swallow than its inconclusive cancer links. As EcoWatch detailed previously:

Coffee plants naturally prefer shade, as they evolved in the understory of the African jungle. But more and more, coffee is being grown in direct sun on monoculture plantations that resemble cornfields. Shade-grown coffee slipped from 43 percent of the world’s farms in 1996 to just 24 percent in 2010. Three-fourths of the coffee farmland in Brazil and Vietnam has no shade tree cover at all. Much of their production is cheaper, robusta beans that are generally used for instant coffee and low-price supermarket brands.

The coffee you choose may be harmful to your health, to the environment or to the growers themselves. Much coffee is grown using pesticides, which has been shown to be detrimental to coffee farmers. Also, pesticides used to combat the coffee cherry borer and coffee rust can remain in the environment.

On large coffee plantations, workers often toil in harsh conditions for subsistence wages. Children as young as six or eight work the fields, and just 13 percent of coffee workers in Guatemala have completed primary education. In contrast to these big plantations, small farmers generally cultivate less than seven acres of land and often struggle to earn more than the cost of production. Fair Trade coffee may or may not help: only the label “Fair Trade Certified” ensures that farmers receive a fair price for their coffee.

Climate change is also threatening crops across the world’s coffee bean belt. According to a report from the Climate Institute, commissioned by Fairtrade Australia & New Zealand, rising temperatures and changing rainfall patterns are already impacting coffee crops from Africa to Central America and the effects will worsen in the coming decades. Global warming could reduce global coffee production 50 percent by 2050, endangering the livelihoods of more than 120 million of the world’s poorest people.

So to my fellow coffee-lovers, if you want to continue enjoying your morning jolt, be kind to the planet and always choose your brands wisely.

Saudi Arabia to House World’s Largest Solar Project

According to the most recent data available from the U.S. Energy Information Administration (EIA), Saudi Arabia is the second largest oil producer in the world. It produces 13 percent of the world’s oil and gets 60 percent of its own electric energy from petroleum.

But the desert nation, whose Paris agreement action plan was rated as “critically-insufficient” by Climate Action Tracker in November 2017, is about to go from zero to hero on the green scale.

On Tuesday, it announced that it would partner with Japanese tech conglomerate SoftBank to build the world’s largest solar power project, Bloomberg reported.

Except that “world’s largest” doesn’t quite cover of size of the project’s ambitions.

According to Bloomberg, the project, which will be built in the Saudi desert, is projected to generate 100,000 jobs and produce 200 gigawatts of power by 2030, 100 times the next biggest planned project, the Solar Choice Bulli Creek PV Plant in Australia, which only aims to produce two.

“It’s a huge step in human history,” Saudi Crown Prince Mohammed Bin Salman told Bloomberg. “It’s bold, risky and we hope we succeed doing that.”

Solar power is a logical choice for Saudi Arabia. It’s capital, Riyadh, averages 8.9 hours of sunshine a day, and the country is also projected to be severely impacted if climate change raises global temperatures above 1.5 degrees Celsius above industrial levels. According to Climate Action Tracker, if global temperatures rise to three or four degrees Celsius, 75 percent of the country would be excessively arid by the end of the century.

“The kingdom has great sunshine, great size of available land and great engineers, great labor, but most importantly, the best and greatest vision,” SoftBank founder Masayoshi Son said of the new project, as reported by Bloomberg.

To provide more context for the scope of that vision, Fortune pointed out that the total capacity of all existing solar installations is around 400 gigawatts, which is only double what the Saudi/SoftBank project plans to produce on its own. China’s Tengger Desert Solar Park, the largest installation currently in operation, generates a little more than 1.5 gigawatts. Since the Saudi project estimates an output of 7.2 gigawatts by 2019, it will more than quadruple the output of the current leader in just one year.

The project is projected to cost $200 billion overall. Saudi Arabia will have to import panels at first, and it will also need to build up the battery capacity to store the solar energy. The first phase will cost $5 billion, $1 billion of which will come from the Vision Fund, which Saudi Arabia and SoftBank are joint investors in.

Son told Fortune he thought the investment would be worth it.

“The project will fund its own expansion,” he said.

The Saudi government’s bold investment in solar power humbles the U.S., which, according to EIA data, is the country currently leading it as no. 1 oil producer.

However, instead of encouraging the solar industry in order to reduce production of fossil fuels, the Trump administration has given it the jitters by announcing a 30 percent tariff on imported solar panels this January.

Pollution Sources Have Increased More Than 50% In Last 8 Years, China’s Environment Ministry Reports

In relation to a new nationwide survey meant to ascertain the amount of environmental damage done by the last 30 years of rapid growth, China’s environment ministry has revealed that the number of pollution sources within the country has increased by over half in just the last 8 years.

Considering that such a large figure makes for bad PR, it’s interesting that the ministry has publicly reported as much — which makes one wonder to a degree whether actual figures could be somewhat higher.

It should be realized, though, that the ministry in question is an entirely new one — the Ministry of Ecology and Environment (MEE) — so perhaps the figures are actually accurate.

As explained by the head of the new ministry’s pollution survey office, Hong Yaxiong: “The goal for the census is to do thorough data collection so that it can reflect the extent of the pollution.”

Reuters provides more: “The government is currently conducting a second nationwide ‘environmental census’ aimed at identifying pollution threats throughout the country. The first was published in 2010. … The environment ministry absorbed new duties formerly held by the land, water, and agriculture ministries as part of the biggest government shake-up in years. It will also now be in charge of climate change and carbon emissions.

“The new census is due to be completed in 2019. According to preliminary estimates, the total number of pollution sources now stands at 9 million, including 7.4 million industrial sources, 1 million in rural areas, and 0.5 million from urban locations, Hong said.

“The first census conducted by the National Bureau of Statistics from 2007 to 2009, uncovered 5.9 million sources of pollution nationwide, with the industrial provinces of Guangdong, Jiangsu, and Zhejiang at the top of the list. The survey also identified 209.8 billion tonnes of waste water, 63.7 trillion cubic meters of waste gas emissions, and 3.852 billion tonnes of industrial solid waste nationwide.”

Interestingly, further aspects of the survey will involve the widespread examination of common soil pollution sources (sources of lead, mercury, and cadmium, amongst other compounds). Considering the scale of the country’s population, and the widespread contamination and destruction of much of its farmland as the result of industrialization, such a survey would seem prudent.

Clean Air Is Now a Status Symbol in the World’s Most Polluted Cities

The Cordis hotel in Shanghai boasts proximity to railways and the airport, a beautiful pool, and double-filtered air. Indeed, air quality seems to be a selling point for this luxury hotel — each of its 396 rooms is equipped with a pollution monitor, The Guardian reports.

Breathing clean air is the new cool in super-polluted cities such as Shanghai, Beijing or Delhi. And it’s just another way that the rich can afford to distinguish themselves from the poor, who are forced to constantly choke on sickening, polluted air.

In 2014, the WHO quantified the effects of toxic air. It is, in short, thought to cause around 7 million premature deaths per year and is responsible for an array of medical conditions including lung cancer and heart attacks.

Governments have tried to downplay the issue. But Asia’s megacities, the pollution crisis became too severe to ignore — the Chinese government was forced to take action or risk undermining its popularity among families worried for their children’s health.

Putting a literal price on clean air might not have been part of the plan, but it seems to be a natural result; the private sector has jumped on the opportunity to make a profit in the face of crisis. From expensive schools in Delhi, attended by the children of the local elite or of rich expats, to luxury hotels like the Cordis, those who can afford it are making clean air a commodity.

“I think back to the days when everyone used to charge for the internet,”  John O’Shea, managing director of the Cordis, told The Guardian. “Now the internet’s like hot water – if you don’t have high speed, fast, easy-access internet for free, then it’s over. The indoor air quality is going to be like that too – if you can’t guarantee your customers much better air quality than the competitors, it’s going to be a fait accompli. It’s already getting that kind of importance.”

In many parts of the world, wealth equals health (or, at least, gives you much more access to it). Prohibitive healthcare costs mean that, if you’re not wealthy, treating your diabetes or cancer may not be an option.

The pollution divide, too, may soon become the new normal.

Countries will undoubtedly continue efforts to clean up their air, but this will likely happen slowly. In the meantime, people who can’t afford to breathe better air will keep suffering from asthma, lung cancer and heart conditions.

Land Degradation Threatens Human Wellbeing

Foto-ilustracija: Pixabay

Land degradation is undermining the wellbeing of two-fifths of humanity, raising the risks of migration and conflict, according to the most comprehensive global assessment of the problem to date.

The UN-backed report underscores the urgent need for consumers, companies and governments to rein in excessive consumption – particularly of beef – and for farmers to draw back from conversions of forests and wetlands, according to the authors.

With more than 3.2 billion people affected, this is already one of the world’s biggest environmental problems and it will worsen without rapid remedial action, according to Robert Scholes, co-chair of the assessment by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES). “As the land base decreases and populations rise, this problem will get greater and harder to solve,” he said.

The IPBES study, launched in Medellín on Monday after approval by 129 national governments and three years of work by more than 100 scientists, aims to provide a global knowledge base about a threat that is less well-known than climate change and biodiversity loss, but closely connected to both and already having a major economic and social impact.

The growing sense of alarm was apparent last year when scientists warned fertile soil was being lost at the rate of 24bn tonnes a year, largely due to unsustainable agricultural practices.

The new assessment goes further by looking at vegetation loss, forest clearance, wetland drainage, grassland conversion, urban sprawl and pollution, as well as how these changes affect human health, wealth and happiness.

Drawing on more than 3,000 scientific, government, indigenous and local knowledge sources, the authors estimate land degradation costs more than 10% of annual global GDP in lost ecosystem services such as carbon sequestration and agricultural productivity. They say it can raise the risks of flooding, landslides and diseases such as Ebola and the Marburg virus.

There are also geopolitical implications. The authors cite evidence of a strong association between land degradation, migration and instability. In dryland regions, years of extremely low rainfall have been associated with an up to 45% rise in violent conflict. Depending on the actions taken by governments to address climate change and the decline in soil quality, the authors estimate between 50 to 700 million people could be driven from their homes by 2050. The worst affected areas are likely to be the dry fringes of southern Iraq, Afghanistan, sub-Saharan Africa and southern Asia.

To counter this, the authors call for coordination among ministries to encourage sustainable production and for the elimination of agricultural subsidies that promote land degradation. They urge consumers to reduce waste and be more thoughtful about what they eat. Vegetables have a much lower impact on land than beef. Farmers are encouraged to raise productivity rather than clear more land. Companies and governments are advised to accelerate efforts to rehabilitate land. There have been several successful projects on China’s Loess plateau, in the Sahel and in South Africa.

The economic case for land restoration is strong, according to the report, which says benefits (such as jobs and business spending) are 10 times higher than costs, and up to three times higher than price of inaction. But in most regions, remedial work is overdue. National governments are not living up to a global commitment to neutral land degradation by 2030.

Participants compared the rundown of land to the 2008 financial crisis. “Back then, people borrowed more money than they could repay. Now we are borrowing from nature at a rate that is many times higher than the world can sustain. The day of reckoning will come,” said Christian Steel, director of Sabima, a Norwegian biodiversity NGO. In Europe, he said, the industrialisation of forest and agriculture is degrading the land. “We are also importing more food and, by doing so, displacing the impact of our consumption. We are fooling ourselves. Disaster doesn’t hit suddenly like in a Hollywood movie. It is already happening gradually.”

“This is extremely urgent,” said another of the co-chairs, Luca Montanarella. “If we don’t change lifestyles, consumption habits and the way we use land, then sooner or later we are going to destroy this planet. Looking for another one is not an option.”

It’s Time for Samsung to Truly Innovate

Photo-illustration: Pixabay
Photo-illustration: Pixabay

Last month at the Mobile World Congress in Barcelona, Samsung announced its new Galaxy S9 and Galaxy S9+, which only recently hit the market. But the event was unexpectedly quiet this year and the reason could be that, beside a few incremental features and larger cameras, new models aren’t really changing much.

Its phones might have the most cutting-edge technology, but the way Samsung manufactures its electronics is still stuck in the Industrial Age. For instance, Samsung uses about 16 terawatt a year, which is equivalent to that of the Dominican Republic, but only 1 percent of that is sourced from renewable energy. Instead of new models, what we really need is leadership tackling climate change across the sector, and a much more aggressive transition by corporations to renewable sources of energy that also extend into product supply chains.

Electronic devices have become more energy efficient, but their increasing complexity means more energy is spent manufacturing them.

Samsung has a unique status in the IT industry. The company has thousands of suppliers across the world, and provides key components to Apple, Oppo, Vivo, Xiaomi, Huawei and many others. If Samsung switches to 100 percent renewables, the impact will create a positive domino effect among other companies, facilitating an even faster transition to 100 percent renewable energy within the sector.

Despite the fact its carbon footprint is growing, Samsung has not yet set emissions reduction or a renewable energy targets for its supply chain, nor made public its top suppliers.

The company announced that it will release a renewable energy strategy by August 2018, but this is nowhere near enough given the scale and urgency of what we are facing. If it really wants to show its leadership, Samsung CEOs need to make climate change a priority and show the ambition to switch its operations to 100 percent renewable energy.

There are benefits for tech companies to switch to renewable energy. The increasing cost competitiveness of renewable energy, with long-term contracts increasingly at cost parity or even beating fossil fuels in many markets, also provides long-term price security. Furthermore, brands that can link their identity to a renewable supply of energy are better perceived by customers, given the growing concern on climate change.

Samsung’s home country of South Korea is also transitioning toward a clean energy system, offering the company an unprecedented opportunity to embrace renewables. Just recently, one of South Korea’s most coal-intensive provinces, Chungnam province, pledged to phase out coal by 2050 and the President has promoted a transition away from fossil fuels to renewables.

What is Samsung still waiting for?

As the world’s biggest smartphone vendor, it’s time Samsung uses its influence and power to really innovate.

This is bigger than electronics. This is bigger than business. This is about the legacy that we can leave for our children.

Sensors Equipped with AI Could Thwart Illegal Deforestation

Photo-illustration: Pixabay
Photo-illustration: Pixabay

Abstractly, we know that the world’s forests are under threat. We lose somewhere between 80,000 and 150,000 square kilometers — about the size of Maine in the best case scenario, and Louisiana in the worst — of the world’s forests every year to human activities.

But it’s much harder to nail down exactly which parts of forest are most at risk, and when, especially because up to 90 percent of tropical deforestation is due to criminal activity, according to the UN. San Francisco-based nonprofit Rainforest Connection believes that machine learning can be the next ally in the good fight.

The team of engineers and developers built a complex system of sensors that can endure extreme weather and other stresses in the rainforest, using modified smartphones powered by solar panels. The key, they say in a blogpost, is to hide the devices — they call them “Guardians” — amidst the trees in vulnerable areas, so they remain hidden. The sensors record the sounds of the forests and upload them onto a cloud-based server in real time.

Google’s AI framework TensorFlow sifts through forest sounds to isolate suspicious noises such as chainsaws and logging trucks in real time.

The software, launched in 2015, is designed to help developers improve services such as speech recognition, or in this case sound detection. Google offers it for free, with a catch. The AI built with TensorFlow can run anywhere, MIT Tech Review reports, but it works particularly smoothly on Google’s cloud platform.

So can Rainforest Connection’s Guardians, powered by Google, really save the rainforest? Forests already have plenty of high-tech systems buzzing around, from drones spraying seeds to planes equipped with LIDAR beams that assess the density and health of the canopy.

Not even the most sophisticated system can make a difference in isolation — observations of surreptitious logging are meaningless if there aren’t laws to protect the forests, and forces to intervene promptly when someone violates those laws.

When the right regulations are in place, keeping an ear out for illegal logging can ensure that conservation laws are put into practice.

Texas Blue Cloud 148 Megawatt Wind Farm Reaches Financial Close, Begins Construction

Photo-illustration: Pixabay

Tri Global Energy has announced this week that its 148 megawatt wind project has reached financial close and will begin construction with investment from Denmark-based Copenhagen Infrastructure Partners and wind turbines supplied by Danish wind turbine manufacturer Vestas.

Three separate announcements were made on Wednesday that confirmed the finalization and beginning of construction work on the new 148.4 megawatt (MW) Blue Cloud Wind Energy Project set to be developed across 19,000 leased acres of privately-owned farmland in Bailey and Lamb Counties in Texas.

Tri Global Energy, the developer of the project, announced that Blue Cloud reached financial close on Wednesday thanks to investment from Denmark’s Copenhagen Infrastructure Partners (CIP) who will also act as the long-term owner and operator of the project. CIP confirmed, for its part, that it will be making an equity investment in the project through their Copenhagen Infrastructure II K/S (CI-II) fund.

At the same time, Vestas announced that it would be providing 135 MW worth of its V126-3.45 MW wind turbines along with a 25-year service agreement.

“Blue Cloud will become our second equity investment in the US onshore wind market that we bring to Financial Close with tax equity investors,” said Christian Skakkebæk, Senior Partner in CIP. “We are glad to continue our successful cooperation with our partners and we are looking forward to see Blue Cloud delivering its first unit of electricity to the grid.”

“This is Copenhagen Infrastructure Partners’ second equity investment in wind in the US and with a service contract lasting a quarter of a century also a strong testament to the partnership we are building and the trust our customers have in our service offerings,” said Chris Brown, President of Vestas’ sales and service division in the United States and Canada. “At the same time, the order expands the 4 MW platform’s footprint in the US, highlighting the platforms’ momentum in North America, and Vestas’ product diversity and flexibility.”

Supply and commission will be conducted by Vestas, with completion expected by the end of this year.

UK To Introduce Deposit Return Scheme For Single-Use Plastic Bottles

Foto: Pixabay
Photo-illustration: Pixabay

A deposit return scheme for single-use plastic drink bottles will be introduced this year in the UK, with the idea being to improve the rate of plastic bottle recycling and thus to reduce litter.

The new plans echo some of those put into place in recent years in a number of other countries in the region (and elsewhere in the world, as well), including in Germany, Sweden, and Denmark.

To provide a basic overview: customers are charged a bottle deposit when buying a drink in a plastic bottle, which can then be redeemed for money or store credit (often via automated return systems) if brought back empty.

The UK’s environment minister Michael Gove was quoted in a public statement on the matter as saying: “We can be in no doubt that plastic is wreaking havoc on our marine environment — killing dolphins, choking turtles, and degrading our most precious habitats. It is absolutely vital we act now to tackle this threat and curb the millions of plastic bottles a day that go unrecycled.”

The new plans are subject to public consultations later this year, reportedly.

Reuters provides more: “British consumers get through about 13 billion plastic drink bottles a year but more than 3 billion are either incinerated, sent to a landfill, or left to pollute streets, the countryside, and marine environment, the government said…The consultations will focus on the details of how the scheme will work along with other measures to increase recycling rates.

“A possible alternative to the deposit return scheme is cash rewards for returning drink containers, the government said. This is often executed by a network of ‘reverse vending machines’ through which a plastic or glass bottle can be inserted into one and the machine returns money.”

These plans follow on the imposition of mandatory plastic bag fees in the UK in 2015 and represent part of a broader push to reduce plastic litter. While such plans aren’t enough on their own to “deal with” the vast problem of plastic pollution, they would/will likely to help to reduce it to a notable degree.

Engie Reports Progress On More Than 600 Megawatts Of Solar & Wind In India, Eyes Stake Sale

Photo-illustration: Pixabay

French energy utility Engie announced major progress in India regarding its renewable energy business in India this month. The company has seen rapid growth in the highly competitive wind and solar power markets in India.

Solairedirect, a subsidiary of Engie operational in India, started commercial operations of a 101 megawatt (DC) solar PV project in the state of Uttar Pradesh. The project has an AC listed capacity of 75 megawatts. The company had secured the rights to develop the project under the federal solar power policy at a tariff of Rs 4.43/kWh (6.8¢/kWh) in June 2016. The company will sell electricity to the Solar Energy Corporation of India (SECI) for a period of 25 years.

The project was launched jointly by the Indian Prime Minister Narendra Modi and the French President Emmanuel Macron following the conclusion of the first-ever summit of the International Solar Alliance in New Delhi earlier this year.

The company also commissioned a 190 megawatt (DC) project in Rajasthan. The project is actually split in two projects, each having an AC listed capacity of 70 megawatt each. The projects are located in the famous Bhadla solar power park which will be home to India’s cheapest solar power projects in a few months. Solairedirect had bid for the projects at Rs 4.35/kWh (6.4¢/kWh) for these projects which was a competitive bid at that time.

Solairedirect finally signed the power purchase agreement for a 338 megawatt (DC) solar power project to come up at the Kadapa solar power park in the state of Andhra Pradesh. The company has placed a bid of Rs 3.15/kWh (4.8¢/kWh) in April last year. The bid was the lowest for any solar power project in India at that time.

The project, with AC capacity of 250 megawatts, faced several delays as the power distribution utilities in Andhra Pradesh initially refused to sign a power purchase agreement (PPA), claiming that they do not require any additional solar power. But as we analyzed earlier, that was not true. The utilities have now agreed to sign the PPA reportedly after NTPC Limited (the company that floated the tender) agreed to ‘bundle’ thermal power with the solar power generated from the project. This would further reduce the price Andhra Pradesh utilities pay.

Engie also won rights to develop wind energy projects in the states of Gujarat and Tamil Nadu. The company will develop 80 megawatts of capacity which it secured through competitive auctions.

ABB AbilityTM SafetyAPP for power generation and water customers enables plant employees to quickly report safety risks, improve situational awareness and reduce potential safety risks.

Since its introduction in 2014 in ABB, SafetyAPP has driven the reporting of 50,000 safety risks and reduced the number of serious incidents in Europe by 50 percent.

Previously, reporting hazards was a lengthy paper-based process that discouraged employee engagement and gave only a partial picture of safety in the company. With the SafetyAPP, businesses have immediate insights and traceability into the safety risks at their sites.

Employees download the app to their smart phones and use it to report any hazard they observe at work, without having to return to their desks to issue a report in another software. Risks reported could range from a slippery floor to unsafe practices observed.

In a simple five-step procedure, which takes about two minutes to complete, employees name the risk they have observed, take a photo and briefly describe it.

Once the report is sent, the app notifies the employee’s safety line manager, who then assigns a person to rectify the risk within a defined deadline.

Not only does the app transform reporting, tracking and managing hazards into a simple procedure, it raises staff awareness of safety and makes employees more observant of safety hazard in their surroundings. ABB data show that the more risks are reported, the fewer serious incidents occur.

One company whose senior management immediately saw the value in the app is multiutility Iren.

“We have more than 6.000 employees working every day at several sites in our territories,” says Massimiliano Bianco, Iren’s chief executive officer. “ABB’s SafetyAPP helps keep our people safe by making it easy to report, track and manage hazards. Its digital format provides us with valuable information on safety at our sites, which we are using to raise awareness to a higher level.”

The SafetyAPP is part of ABB Ability™ Collaborative Operations portfolio for power generation and water, which enables customers to improve the safety, performance and profitability of their people and operations. ABB Ability is our unified, cross-industry digital capability — extending from device to edge to cloud — with devices, systems, solutions, services and a platform that enable our customers to know more, do more, do better, together.

ABB is a leading provider of integrated power and automation solutions with unparalleled experience in partnering with the energy and water industries, bringing customers improved operations and sustainable progress. We deliver integrated and secured digital systems, services and solutions to automate and optimize the performance of conventional and renewable power plants and water facilities.

The burgeoning offshore wind industry in Taiwan has received yet another massive boost after one of the world’s leading offshore wind energy companies, MHI Vestas, announced that it has signed four Memorandums of Understanding with leading local companies to begin building out their supply chain in the region.

MHI Vestas — the joint offshore wind partnership between Mitsubishi Heavy Industries and Vestas — announced on Wednesday that it had signed four Memorandums of Understanding (MoUs) with four Taiwanese companies, namely CSMC for wind towers, Tien Li for blade manufacturing, Swancor for composites and resins, and Formosa Plastics Corporation for materials for blade manufacturing. The agreements are part of MHI Vestas’ ongoing manufacturing strategy in the region.

“The Taiwan offshore wind market has impressively put itself in a front-runner position in the region,” explained incoming MHI Vestas CEO, Philippe Kavafyan. “Having the benefit of early selection of a portfolio of projects allows us to enter into these manufacturing agreements with great confidence. We are honoured to announce these partnerships today – partnerships that will spur the expansion of highly-skilled, local manufacturing jobs.

“In bringing our market-leading 9 megawatt (MW) turbine platform and a rich heritage of energy infrastructure experience through Mitsubishi Group, MHI Vestas is well positioned to be the market leader in Taiwan.”

The MoUs also build on Mitsubishi Group’s existing experience in energy infrastructure in Taiwan, giving MHI Vestas a leg-up in its build-out.

“Mitsubishi Corporation (MC) has been actively operating in Taiwan since the 1940s, especially in the power business,” added Mitsubishi Corporation Taiwan Chairman & CEO, Mr. Koji Nemoto. “MC has installed a number of power plants together with MHI for Taipower and other owners. At the same time, MC has been building a great relationship with MHI Vestas through the offshore wind business in Europe.”

“With this background, we highly welcome and fully support MHI Vestas for its market entry to the emerging offshore wind market in Taiwan and we are confident that they will greatly contribute to realising the energy transition in Taiwan.”

The move by MHI Vestas follows a bevvy of similar announcements from offshore wind competitors Siemens Gamesa and Ørsted (formerly DONG Energy) over the past few months, which highlights a new focus on the Taiwanese offshore market and its surrounding regions.

In January of last year, DONG Energy invested in Taiwan’s first offshore wind farm, the 120 MW Formosa 1 project set to be developed by local company Swancor Renewable, and also supported by Macquarie Capital. In December, the company now known as Ørsted announced that it had moved several steps closer to beginning work on the massive 2 gigawatt (GW) of Taiwanese Greater Changhua offshore wind projects, acquiring environmental approval and securing a subsea cable partner in Taiwanese Woen Jinn Harbour Engineering.

“Local content has been placed at the center of our project development activities,” said Matthias Bausenwein, Ørsted’s General Manager Asia Pacific and Chairman Taiwan. “In the past year, the local Ørsted team has met over 170 Taiwanese companies and identified 15 companies for close collaboration. CWP has a very strong background in large-scale steel manufacturing and shown significant ambition to invest in offshore wind manufacturing business.”

At the same time, the newly-formed Siemens Gamesa has been making its own way into the Taiwanese offshore wind market, signing in December a Memorandum of Understanding with the Taiwan International Ports Corporation to investigate the possibility of developing an offshore wind manufacturing and deployment site. Siemens Gamesa also opened offices in Taipei, the capital of Taiwan, and signed a second MoU to explore potential manufacturing sites at the Taichung Harbor for offshore wind components, office facilities, and staging areas including storage, pre-assembly, and quayside load-out.

“The promising potential of the Taiwanese offshore market combined with our positive experience with the government has encouraged us to intensify our efforts,” said Andreas Nauen, CEO Offshore, Siemens Gamesa Renewable Energy. “We are convinced that this emerging market offers interesting business opportunities. As one of the world’s leaders within the offshore wind industry, we look forward to gaining a foothold in this market.”

McDonald’s has become the latest big name brand to step up efforts to tackle plastic waste, revealing it is to trial more sustainable alternatives to plastic straws and is closing in on ensuring 100 per cent of its packaging is recyclable.

In an interview with Sky News, McDonald’s UK boss Paul Pomroy said the company would soon be trialling paper straws in two of its restaurants, as part of a wider effort to reduce plastic straw waste.

“[One thing] we’re looking to do is to move to recycled paper on the straws and biodegradeable paper straws,” he said. “That test, I’m really proud to say, will start next month, here in and around London.”

He added that all McDonald’s restaurants would also seek to reduce the number of plastic straws they hand out. “Customers have told us that they don’t want to just be given a straw, they want to have to ask for one, because straws is one of those things that people feel passionately about, and rightly so,” hetold the broadcaster. “We’re now moving those straws behind the front counter, so if you come into McDonalds going forward, starting next month, you’re going to be asked if you want a straw.”

Pomroy also confirmed work was continuing to ensure all of the company’s packaging is recyclable. “Eighty per cent of what you have in Mcdonald’s is now recyclable, we’ve offered recycling facilities for our customers and I’m really proud of the journey we’ve been on,” he said. “The only thing left for us now to move forward on is the lids that go on to our cups, we’re working with our suppliers… We’re really close. It’s one of those things, technology is advancing all the time and we hope within the next year to be able to have a hot lid and a cold lid that serves the same purpose that’s recyclable.”

The news comes on the same day as the government announced it is to consult on the introduction of a national Deposit Return Scheme that could cover all drinks containers.

It also follows a raft of pledges from retailers and hospitality firms to crack down on plastic packaging, including McDonald’s recent global announcement it is to accelerate efforts to curb packaging waste and adopt a science-based emissions target.

In related news, Starbucks last week stepped up its efforts to ensure disposable coffee cups are more widely recycled with the announcement of a $10m partnership with Closed Loop Partners and its Center for the Circular Economy to deliver a new “NextGen Cup Challenge”.

The coffee chain said the technology challenge was “the first step in the development of a global end-to-end solution that would allow cups around the world to be diverted from landfills and composted or given a second life as another cup, napkin or even a chair – anything that can use recycled material”.

Colleen Chapman, vice president of Starbucks global social impact, said the project amounted to a “moon shot for sustainability”.

“No one is satisfied with the incremental industry progress made to date, it’s just not moving fast enough,” she said. “So… we are declaring a moon shot for sustainability to work together as an industry to bring a fully recyclable and compostable cup to the market, with a three-year ambition.”

The company said the industry-wide technology challenge would run alongside an internal research project to trial a new bio-liner, made partially from plant-based materials, for use in paper cups. The six month internal trial will test both the environmental impact of the new material and whether the cup’s liner can meet stringent safety and quality standards. Starbucks said the trial marked the 13th internal test of its kind in the last year alone, as the company works to deliver a “Greener Cup”.

When VODAVODA first appeared on our market in 2004, in just three months, it won millions of consumers and a third of the domestic market of bottled water. The water factory stopped operation in the meantime, VODAVODA disappeared from the shelves and the rest of us were deprived of one of the best quality water coming from the natural and healthy environment in Banja Vrujci. For three years now, this brand has been available again for sale and it gradually occupies a place that it used to have on the domestic and foreign markets. With Vojin Djordjevic, we discussed the importance of natural mineral water, which without any artificial filtration and processing is only bottled in the new plant with a striking name “The House of Water”.

EP: Are you satisfied with the comeback of VODAVODA to the domestic market?

Vojin Djordjevic: We are extremely pleased that the results of the achieved sales show a very good trend, although the figures are still not on the profit side. We invested much more than we earned, but I am sure that, due to the special quality of VODAVODA and the beneficial effect on the health of all who drink it, all investments will be returned in the future. We are satisfied that an increasing number of consumers find out about the existence of unspoiled nature and water source owned by Banja Vrujci. It is not necessary to travel to this water spring in order to enjoy this water. Packed in a bottle of VODAVODA, it is available to us at almost all the retail outlets in our country. We are on a good path that has become our obligation and we must not stop.

EP: The promotion of VODAVODA brand is based on water properties from a depth of 605 meters and the absence of its processing. Do you consider the information that water is not being processed but bottled directly, as an important one for the consumers?

Vojin Djordjevic: This information is important for every consumer of bottled water. Such unprocessed water is very rare in Serbia and in the world. When something is created, as we create the world brand VODAVODA, it is necessary to think not only of ourselves but of factors in the process of creation: people, nature, quality, future. Only such a brand is true, durable and, above all, good. We have done everything that VODAVODA is natural: that it comes directly from nature to the consumer and that nature is left untouched. That is the essence. You know, the first contact with water from Banja Vrujci with the outside world is the moment when the consumer opens the bottle of VODAVODA.

EP: What does your team do so that the consumer learns about the quality of VODAVODA?

Vojin Djordjevic: The business strategy of VODAVODA brand is based on well-founded principles that are a sound basis for a quality upgrade. This also applies to the area of water quality that we offer to consumers. The quality of water is not proved by aggressive marketing or large-scale sales, but by science-based certificates, issued by accredited top experts who, on the basis of the detailed analysis, confirm quality. Our team, according to the brand strategy, sent VODAVODA for an analysis to top-level and relevant scientific institutions in our country and in the world, and then, with justified facts, addressed consumers. First of all, we emphasize that VODAVODA is the holder of the world’s most prestigious certificate – NSF. It guarantees to the consumer safety, consistency in the same mineral composition always and superior quality achieved by the highest global standards in the bottling process. This year we have completed another long-term research in our scientific research institution with the highest credibility. As we expected, the results obtained, are exceptional and will soon be officially announced. In science, there are clear parameters for assessing water quality, and there is no mistake.

EP: Can you explain to us what you wanted to say or highlight when you named the plant “The House of Water“?

Vojin Djordjevic: We do not have a water processing factory that processes water, like other brands. We do not use chemicals for water treatment, and we do not have harmful substances that pollute nature, and we recycle the packaging. We do our best for VODAVODA to be the brand with so-called “zero waste”. This is the latest concept of sustainability of a healthy environment, which is no longer enough to create unwanted waste, and then neutralize it, but you must follow the course of nature that prevents the development of an unhealthy substance. That’s why we have been thinking about what to name the production itself for a long time. The usual name for our industry is “factory”, but it was not appropriate for us, because it means machines that change water by using chemicals, and we do not do it. We were not happy with the “bottling plant” designation. It was not until the solemn opening when the priest said: “Today we are happy because we are in this house of water …”, we realized that he said the essence. It is a home that symbolizes everything we want to say to the world – to preserve, nourish, give away and always give birth to water over and over again.

SOCIALLY RESPONSIBLE BUSINESS AND SUSTAINABLE DEVELOPMENT

The quality of water is supported by laboratory analysis carried out in international accredited laboratories. Thanks to this, the VODAVODA brand is classified as a significant promoter of environmental protection. The Strategy of Corporate Social Responsibility and Sustainable Development envisages enabling “The House of Water” to use clean energy. Accordingly, a solar power plant will be installed to obtain heat and electricity. This will completely round up the environmental sustainability of VODAVODA.

EP: Is it easy to preserve this balance between the man and nature?

Vojin Djordjevic: Possibility to master the technology of water bottling with the highest quality process, brings me joy, but also the responsibility. The obligation in “The House of Water” is to use technology in a way that is even more stringent than the one prescribed by law. By using modern methods of preserving nature and the environment, we take care not to jeopardize or disturb its balance.

EP: NFS certificate has enabled VODAVODA to be on the world market as well. Was it necessary to introduce certain technological novelties in “The House of Water”?

Vojin Djordjevic: No, it was not. NSF certificate just confirmed that we did everything in the right way and that we just have to continue doing so. We know that the water we draw from the spring in Banja Vrujci is perfect, with an ideal mineral composition and naturally well balanced. On domestic, but also on the world market, you have the least water that has not been processed. It is a real treasure.

EP: What do you think is crucial for the good placement of such a product on the foreign market?

Vojin Djordjevic: VODAVODA became a hit on all the markets on which it appeared. In Kuwait, where it appeared this year, it provoked a sensation. There are already indications that this will happen again in other countries in the Persian Gulf. Foreign distributors contact us for bottle design. They unquestionably estimate that their customers will first reach for the unique bottle shape on the shelf in the supermarket. Getting to know the composition and natural properties of water is the next step that leads to a lasting relationship with the consumer. Natural mineral waters, such as VODAVODA, are very rare in the world today.

EP: At one time, VODAVODA was better sold on the Taiwan market than the famous Evian water. Do you believe that you will repeat that success?

Vojin Djordjevic: The fact that in 2006 we sold more water in Taiwan than world leader is a proof that consumers reward quality. This is one of the events that motivated me, even when it was most difficult, not to sell the brand VODAVODA and not to leave Banja Vrujci. I was also encouraged by the positive reactions of visitors to fairs and information from the market. I do not give up on the idea that VODAVODA remains unprocessed. I believe that natural quality water with exclusive design has no competition. I do not have a dilemma that VODAVODA will surpass that success in Taiwan.

EP: You have also taken steps that have a positive impact on the development of Banja Vrujci, and the improvement of the lives of its inhabitants. What’s your contribution to the progress in the spa environment?

Vojin Djordjevic: We try to contribute to the development of Banja Vrujci, but it is not appropriate if I talk about it. It is better to ask the people of Banja Vrujci about this. Our most important goal is to preserve and protect the nature of this incredible place. By that, I mean the use of renewable energy sources in the whole Banja and then in the region. In addition, we want people of that region to live in prosperity, peace and spiritual joy. I gave the vow to restore the church Protection of the Theotokos, whose ruins we found during the construction of “The House of Water”. The locals tell me that today they feel the existence of sin because of the demolition of this church after the Second World War. I am convinced that the renewal of the church will bring good to everyone.

EP: About 80% of bottled water from domestic springs is in the hands of foreign companies. In addition to your “The House of Water”, there are only “Heba” in Bujanovac and “Milan Toplica” in Prokuplje, with a few smaller producers in domestic ownership. Do you think we are managing water resources intelligently?

Vojin Djordjevic: Serbia is rich in water resources and has the potential to prudently manage this wealth itself, despite the fact that world trends in water are dictated by multinational companies that own two large sources in our country. For the production and distribution of bottled water, huge investments are needed, the ones that multinational companies have. It is very di cult for the domestic manufacturer to compete with such a strong competition. Empowering domestic production and the availability of bottled water could create a natural balance. Domestic bottled water would outdo the quality of the waters of multinational companies and thus conquer the market, while multinational companies would continue to dominate with their advertising. Our example can help potential new water producers. VODAVODA has achieved competitiveness in the market for water quality and packaging design.

EP: In this regard, there is more and more talk about the sale of spas in Serbia located at the sources of geothermal and mineral water. How could it affect your local community?

Vojin Djordjevic: Spas in Serbia have a long tradition. Their many sources of geothermal and mineral water are known for their healing properties, and the natural environment for centuries have been a subject of admiration. We would all like to have our spas come into the hands of those who will take care of them in a way that their quality deserves so that we are once again proud of the top quality and top service. I believe that the state knows what the interests are and that clear regulation in the process of promoting spa tourism is prescribed.

For me, Banja Vrujci is supreme. Because of its nature and people you just grow fond of the region, it becomes a part of you as if you were born there. We have found a way to contribute to the development of tourism in Banja Vrujci and we want to further improve it as much as possible. VODAVODA performs all of its business communication, not only production, in Vrujci. Guests from abroad, distributors, customers, journalists, all who come to us on business stay in our hotel where we present the beauty of spa tourism. Full of impressions they take to their worlds some of the most beautiful stories about the place where VODAVODA wells up. I would like people from all over the world, not just because of business, but because of the beauty of this region, to come to Banja Vrujci and see where VODAVODA is bottled.

EP: The World Economic Forum recently released warning results of water research from the water supply system on five continents indicating the presence of micro-particles in almost all water samples. No one knows how this will affect people’s health, but it is obvious that the plastic we throw in watercourses, ends up in water supply systems. In your opinion, how can we influence people’s awareness of the importance of preserving watercourses and sources?

Vojin Djordjevic: We should all be aware that water remembers everything, every thrown plastic bag, PET packaging, a discharged chemical. Campaigns to raise awareness precisely serve to inform and encourage people how to dispose of waste properly. They remind us to think of ourselves and of others, as well. Controlled use of products that are unhealthy for nature is only the remedy of consequences, but not the cause of the problem. However, the question arises why, at all, are those products that threaten the nature and the man in it produced. Today’s world is not able to completely and quickly get rid of the production of products that pollute nature. Still, we can be caring. On a personal level, we can take care not to waste the packaging, and on a professional level, factories should act responsibly with waste materials. Continuous campaigns and the availability of a waste disposal sites we make it easier for the individual to be responsible. The legislation, as well as credit facilities for companies, enable the introduction of a system for waste treatment and recycling of packaging.

We are all participants in this global problem and we are all together responsible for the outcome. Therefore, there is no such thing as one man, one source, one river, one country, but our common land and one nature – our planet Earth.

The Green Investment Group, now owned by Macquarie Group, has this week announced the acquisition of a 25% stake in the 210 megawatt (MW) Westermost Rough offshore wind farm from Marubeni Corporation.

Announced on Tuesday, the Green Investment Group (GIG) — which was recently acquired by Macquarie Group and now acts as the Group’s specialist green energy principal investment business — has acquired a 25% stake in the Westermost Rough offshore wind farm which was held by the Marubeni Corporation, a Japanese sōgō shōsha company with holds interests in a variety of sectors.

The Green Investment Group’s 25% acquisition increases its existing stake in the Westermost Rough offshore wind farm, that is held as part of a consortium with Macquarie European Infrastructure Fund 5 (MEIF5) and the Universities Superannuation Scheme (USS). The remaining 50% of Westermost Rough is held by project developer Ørsted.

The 210 MW Westermost Rough offshore wind farm was officially inaugurated in July of 2015, and is made up of 35 of Siemens Gamesa 6 MW wind turbines. Located 8 kilometers off the Holderness coast in the United Kingdom, it generates enough electricity to supply the needs of around 150,000 British households each year.

“Westermost Rough is a landmark project in the evolution of the offshore wind industry, both in the UK and internationally,” said Edward Northam, Head of GIG in Europe. “The technical and financial innovations deployed during the development, construction and operation of the wind farm have helped improve performance levels and reduce the cost of wind power generation, making it significantly more cost competitive. We are extremely proud of this pioneering green investment.

“Alongside Ørsted, Marubeni has been an excellent partner on the project, which owes much to the company’s pioneering and collaborative spirit. Marubeni has played a crucial role in supporting the growth of the UK and global green economies and we look forward to exploring further opportunities to cooperate in future.”

“Marubeni is committed to actively support the global energy transition to renewable energy with the aim to increase renewable energy capacity in our portfolio to 20%, doubling the past target,” added a spokesman for the Marubeni Corporation (PDF). “In order to achieve that ambition, Marubeni is keen to deploy the skills and knowledge we gained from our investments in offshore wind farms, including Westermost Rough.

“GIG is a leading player in the offshore wind sector and has been an important partner for us. We look forward to exploring further collaboration opportunities with them in future.”

Arctic Sea Ice Hits Second-Lowest Winter Peak on Record

Arctic sea ice has experienced its maximum extent for the year, reaching 14.48 million square kilometers (approximately 5.59 million square miles) on March 17—the second smallest in the 39-year satellite record.

The provisional data from the National Snow and Ice Data Center (NSIDC) shows the 2018 winter peak only narrowly avoided taking 2017’s record.

The run of low extents in recent winters suggests that “profound ice loss is no longer limited to summer but now extends across all seasons,” an NSDIC scientist told Carbon Brief.

Meanwhile, in Antarctica, sea ice has already reached its minimum extent following the summer melt season. This also clocked in as the second lowest on record.

As the northern hemisphere emerges from winter, the annual expansion of sea ice in the Arctic slows to a stop. This peak signals the start of the melt season in spring and summer.

Using satellites, scientists can mark this point every year, recording when the Arctic sea ice hit its largest extent and the size it reached. It is one way of monitoring the “health” of the Arctic.

Early indications suggest that Arctic sea ice reached an annual maximum of 14.48 million square kilometers (sq km) on March 17. This is the second lowest winter peak in the 39-year satellite record—just 60,000 sq km larger than the 2017 record—and 1.16m sq km smaller than the 1981-2010 average.

At the point of this winter’s peak, there were two particular areas with very low sea ice extents, the NSIDC said—the Bering Sea (in the Pacific Ocean between Russia and Alaska) and the Barents Sea (in the Atlantic Ocean to the north of Scandinavia).

This year has already been marked by new records, with both January and February seeing the smallest average sea ice cover for their respective months. The winter peak looked set to be a record itself before a spell of cold conditions caused a late growth spurt in mid-March.

The Arctic winter has been marked by some unusually high temperatures, which has in turn pushed bitterly cold conditions over Europe in recent weeks.

This warmth has also likely affected how thick Arctic sea ice is at the moment, said Andrew Shepherd, professor of earth observation at the University of Leeds. He told Carbon Brief:

“Although Arctic sea ice started this winter about 5cm thicker than the previous year, there was slower growth in December—possibly as a result of the relatively warm weather—and by the end of last month it was around 166cm thick, almost identical to 2017.”

Although Arctic sea ice has reached its maximum extent, it will take a little longer for it to reach its peak volume for the season, added Shepherd:

“In most years, Arctic sea ice continues to thicken for a few more weeks after the peak extent is reached as it usually takes a while for summer heat to reach the far North, and so we don’t expect the maximum volume to occur until mid-March.”

This year’s near-record low extent for the winter maximum follows new records in 2015, 2016 and 2017.

This means that the four lowest maximum extents in the satellite record have all occurred in the past four years, noted the NSIDC.

The pattern shows that it is not just the summer where significant sea ice loss is seen, said Julienne Stroeve, a professor of polar observation and modeling at University College London and senior research scientist at the NSIDC. She told Carbon Brief:

“Profound ice loss is no longer limited to summer, but now extends across all seasons. These winter changes will help hasten the transition towards a seasonal ice-free Arctic.”

For example, NSIDC data shows average sea ice extents in January and February are declining at a rate of 3.3 percent and 3.1 percent per decade, respectively.

While the Arctic has been gaining ice over the cold, dark winter, Antarctic sea ice has been melting through the southern hemisphere summer.

Antarctic sea ice reached its summer minimum at the end of February, clocking in at 2.18m sq km. This is the second lowest minimum extent in the satellite record, 70,000 sq km larger than the record set in 2017.

The 2017-18 melt season had begun low. Its starting point was the second lowest winter maximum on record in October. It “went downhill from there,” explained Dr. Ted Scambos, senior research scientist at NSIDC and lead scientist for their science team. He told Carbon Brief:

“A big factor in the rapid loss in November and December was the growth of a large area of open water within the pack, the Maud Rise Polynya. This is thought to be due to ocean upwelling driven by deep currents that pass over a large seamount [underwater mountain] in the Weddell Sea. This then was breached by the retreating ice edge.”

At the point of the minimum last month, “almost every area of the Antarctic coastal ocean had less sea ice than normal,” noted Sambos, “except for the western Weddell Sea—pressed against the eastern side of the Antarctic Peninsula—that was normal in extent and fearsomely well-packed.”

Antarctic sea ice extent has seen a huge amount of variability in recent years. This has taken scientists by surprise, said Scambos, as it follows several decades of relative stability that “appeared to show a slight upward trend in sea ice.” He explained:

“The past five years have seen both all-time high levels—in September 2014—and astonishing record lows—in October/November of 2016. Moreover, a new look at early satellite data from the 1960s confirmed that the Antarctic sea ice system is far more sensitive to seasonal and inter-annual weather and climate differences than had been appreciated before.”

This variability means that recent changes to Antarctic sea ice “can’t really be said to be responding to the general global trend in temperature,” said Scambos—unlike sea ice in the Arctic.

While other data shows that “Antarctica’s climate and ocean are indeed changing,” it may take longer to be able to draw robust conclusions about how sea ice will be affected by human-caused warming, said Scambos:

“It may require another decade or two still before we can say with confidence how Antarctica’s sea ice will respond [to climate change]—at least, if the basis is observations.”
