The nation's largest electric producers continue to substantially reduce emissions of key air pollutants, the latest comprehensive analysis of U.S. power plant emissions shows. The new report analyzed publicly reported data on carbon dioxide (CO2), nitrogen oxides (NOx), sulfur dioxide (SO2), and mercury emissions from the nation's 100 largest electric power producers, which account for 85 percent of the nation's power production.

Environmental advocacy organizations Earthjustice, the Center for Biological Diversity, and Friends of the Earth filed a lawsuit against the EPA to accelerate the completion of an "endangerment finding" that would allow the agency to regulate CO2 emissions from U.S. aircraft. The EPA was expected to finalize a proposal for an endangerment finding in mid-2014. 

Carnival, docked in the spotlight when it received the New Economy's Clean Tech Award for Best Marine Solutions Company. The award recognized Carnival's decision to install a new exhaust filtration system on its North American ships, at an estimated cost of $180m

Carnival Corporation will spend $180 million to install scrubbers designed to reduce sulfur emissions on 32 ships. In return for installing the technology, the EPA will exempt the ships from its low-sulfur fuel mandate.

The Environmental Protection Agency's rule to limit greenhouse gas emissions by power plants has been overturned by the Supreme Court. The 5-4 ruling said the EPA was wrong to not have "properly" considered the "punishing costs" of abiding by the rule. However, many utilities have already started to make changes to be in compliance

Coca-Coca, Dow Chemical and a slew of other players are teaming up with the nonprofit giant to attack a problem that has been explored very little up to now. 

China's largest online travel agency, began selling haze travel insurance to compensate domestic tourists that spend time in major cities affected by smog. Travelers will be able to file claims if they spend at least 2 days in cities with high smog levels.

Over five trillion pieces of plastic are floating in our oceans says most comprehensive study to date on plastic pollution around the world

An Apple supplier in China making iPhone and iPad parts violated a number of health and safety, environmental and human rights laws, according to a report released by China Labor Watch and Green America.

PepsiCo announced that its transportation fleet reduced fuel consumption by 24% from 2010 levels, enabling the company to avoid 55,000 metric tons of CO2 emissions. PepsiCo also announced new efforts to seek lower-carbon fuels from suppliers, join the Business for Social Responsibility's Future of Fuels program, purchase additional electric delivery vehicles, and help to develop appropriate U.S. fleet fuel efficiency standards.

China's state planning agency has ordered the city of Shanghai and the provinces of Zhejiang, Jiangsu and Guangdong to draw up plans to reduce coal consumption in a bid to improve air quality, according to a policy document released on Wednesday.

A Global Commitment to eradicate plastic waste and pollution at the source has been signed by 250 organisations including many of the world's largest packaging producers, brands, retailers and recyclers, as well as governments and NGOs.

Risk in over-50s increases by 40% where highest nitrogen oxide levels exist, study shows

Pokonobe Associates is recycling commercial plastic fishing nets to make the lightweight, stackable blocks for a new version of its Jenga game. The company's Ocean Jenga also will educate consumers about ending ocean pollution, about 10% of which is caused by discarded or lost fishing nets.

Scientists are still trying to unravel the damaging effects of ground-level ozone on life on earth. But as the world warms, their concerns about the impact of this highly toxic, pollution-caused gas are growing.

More than 70 different technologies are available to improve the efficiency of a trucking fleet. These include changes to powertrains and chassis, low-rolling-resistance tires, and enhanced tractor aerodynamics. Finding the right mix to improve a specific fleet can be daunting. Carbon War Room partnered with the North American Council for Freight Efficiency (NACFE) to publish a series of Confidence Reports-objective assessments of the fuel efficiency savings of these technologies. The reports were cited by U.S. EPA in its Greenhouse Gas Pollution Prevention rule-making proposal. 

A new short film featured by National Geographic highlights the plight of the Sargasso Sea - a diverse ecosystem of free-floating seaweed and unique wildlife - that is threatened by plastic waste. From microplastics to bioaccumulation, Care About the Ocean? Think Twice About Your Coffee Lid walks viewers through the dangers of plastic pollution in the Sargasso Sea (and other parts of the ocean) - and for human health.

Drone boats will soon hit the famous, rusty bike-filled canals of Amsterdam. The ambitious "ROBOAT" project, a collaboration between the Massachusetts Institute of Technology (MIT) and the Amsterdam Institute for Advanced Metropolitan Solutions (AMS), will start a five-year trial of the vessels from 2017 to give the multi-purpose boats all sorts of interesting tasks for the busy waterways. The boats will support an array of sensors that can measure water pollution and quality, making assessments about how best to improve the environment. "Water is the bearer of life," says Arjan van Timmeren, professor and scientific director at AMS. "By focusing on the water system of the city, ROBOAT can create opportunities for new environmental sensing methods and climate adaptation."

Communities on the frontlines of fossil fuel development are taking a stand against dangerous fossil fuel projects. Take a look at the big fight in the small town of Kalama, Washington. The Chinese government is planning to build the world's largest methanol refinery to convert fracked natural gas to liquid methanol for export to China to make plastics. From a greenhouse gas perspective, this fight is a big deal. The methanol refinery alone would use more natural gas than all industry in Washington combined. Flip it around: If we win this one battle and stop the methanol refinery, we stop the equivalent of doubling industrial natural gas usage in Washington State. While the gas industry tries to spin natural gas as clean, new science shows just the opposite. The bulk of natural gas is methane, a potent greenhouse gas. Methane leakage from gas wells and pipelines led scientists to conclude that fracked gas can be as bad coal for our climate. And it gets worse. Gas production in North America relies heavily on fracking, a process famous for polluting air and water, endangering the health of nearby residents.

Leaders of eight major seafood companies and fish feed organizations signed a pledge for ocean sustainability after a kickoff meeting of the Seafood Business for Ocean Stewardship last month in the Maldives. Signatories agreed to improve transparency in their own operations, build on and share best practices, engage in science-based efforts to improve fisheries management and productivity, work toward pollution reduction goals, and support the development of new sustainability technology and initiatives.
