The organizations cite research undertaken by universities, government agencies, laboratories, plastic trade associations and NGOs that have concluded oxo-degradable plastics are not suited for long-term reuse, recycling or composting. Instead, evidence has shown that these plastics often fragment into small pieces often not visible to the naked eye; those microplastic particles in turn often end up in both soil and oceans.

"Tropical forests used to absorb carbon. Now they emit as much as all US transit" - a standout headline as a new study published by Science magazine caused a bit of a media stir. Once considered an all important carbon sink, the study is suggesting that tropical forests have reached a significant turning point.

According to the International Organization of Vine and Wine (OIV), an industry group that supports research and development of wine and other grape-based products, 2017 will prove to be a rough year for vinters worldwide. The worst harvest since 1961, largely due to extremes in hot and cold temperatures in leading wine-producing countries such as France and Italy, have led to lower yields at harvest time.

New study shows we've been underestimating nature's role in tackling climate change.

Earlier this year, around Earth Day, Walmart announced an ambitious plan to work with its supply chain to reduce greenhouse gas (GHG) emissions by one gigaton. I decided to run the numbers to see what role source reduction, specifically in Walmart's packaging, could play.

36 major brands and retailers have now signed up to the 100% by 2025 pledge, including four of Forbes magazine's list of the world's ten largest global apparel brands, and three of the top 10 UK clothing retailers.

British fast food restaurants and grocery chains, including Tesco, Morrisons and McDonald's, buy their chicken from Cargill, which feeds its poultry with imported soy, much of it apparently coming from the Bolivian Amazon and Brazilian Cerrado - areas rapidly being deforested for new soy plantations.

When it comes to the private sector's efforts to curb climate change, the rubber hit the road at New York Climate Week.

Unprecedented momentum is being delivered by over 600 companies committed to bold climate action, through the We Mean Business coalition's Take Action campaign. The campaign brings together strategic climate commitments, facilitated by the We Mean Business coalition partners, which are collectively helping these companies tackle some 2.31 gigatons of Scope 1+2 emissions - equivalent to the total annual emissions of Russia. These initiatives are also helping companies to harness climate action as a driver of innovation, competitiveness, risk management and growth.

In June, C&A, the international Dutch chain of retail clothing stores, launched a line of T-shirts certified to the Cradle to Cradle standard, meaning that they were designed and manufactured in a way that is benign to the environment and human health, and whose materials can be recirculated safely back into industrial materials or composted into the soil.

Announced today at Climate Week NYC 2017 in New York, global financial institutions Citi and JPMorgan Chase & Co. have joined The Climate Group's RE100 campaign with CDP, committing to source 100% renewable power across their global operations by 2020. Other companies joining the RE100 initiative are one of the fastest-growing beverage companies, Califia Farms, and UK investment management company Jupiter Asset Management. The announcements follow news last week that The Estée Lauder Companies, Kellogg Company, DBS Bank and Clif Bar & Company have also joined RE100. 110 of the world's most influential companies are now generating demand for over 150 TWh renewable energy annually - more than enough to power New York State.

Britain is phasing out its coal-burning power plants, with the last one slated to be shuttered by 2025, if not sooner. It is a startling development for the nation that founded an industrial revolution powered by coal.

As the annual Climate Week NYC launches today, more companies are announcing their commitment to carbon emissions reduction targets. And they are doing so through using the guidelines set by the Science Based Targets initiative, which provides a framework that its supporters say can help companies stay competitive while doing their part to mitigate climate change.

Volkswagen is making another electric vehicle pledge, this time with promises to bring 80 new electrified vehicles to customers by 2025 and offer customers at least one electrified version of every model across the company by 2030.

When people picture sand spread across idyllic beaches and endless deserts, they understandably think of it as an infinite resource. But as we discuss in a just-published perspective in the journal Science, over-exploitation of global supplies of sand is damaging the environment, endangering communities, causing shortages and promoting violent conflict.

France's government has unveiled a law to ban all production and exploration of oil and natural gas by 2040 on the country's mainland and overseas territories. The move is largely symbolic, however, as France's oil and gas production represents just 1 percent of national consumption - the rest is imported. The ban, which the government claims is a world first, is part of a larger plan to wean the country's economy from fossil fuels, encourage clean energy and fulfill France's commitments under the Paris Climate Agreement to curb global warming.

This series of visualizations shows how some of Earth's key climate indicators are changing over time.

These celebrities suck but you probably do too. We use 500 million plastic straws every day in the U.S. Many of those plastic straws end up in our oceans, polluting the water and harming sea life. If we don't act now, by 2050 plastics in the ocean will outweigh the fish. One small change can have a big impact: #stopsucking on plastic straws.

Potent, climate-warming gases are being emitted into the atmosphere but are not being recorded in official inventories, a BBC investigation has found. Air monitors in Switzerland have detected large quantities of one gas coming from a location in Italy. However, the Italian submission to the UN records just a tiny amount of the substance being emitted. Levels of some emissions from India and China are so uncertain that experts say their records are plus or minus 100%.
