While automakers work to meet stricter carbon-emissions standards, another sector of the U.S. economy has already made notable progress in reducing ts emissions. Carbon-dioxide (CO2) emissions from electricity generation during the first six months of 2016 were the lowest since 1991, according to the U.S. Energy Information Administration (EIA)... Carbon emissions from U.S. power generation fall to 25-year low

Last week, the German Federal Council adopted a bipartisan measure that would ban all internal-combustion engines on German roads after 2030. While its actions only apply within Germany, language in the measure asks the European Union to ensure that all such cars are banned within the EU after that year at the latest. Type approval for road... 
After much discussion, the United Nations' aviation agency plans to set limits on emissions from international airline flights. The agreement ratified by members of the UN International Civil Aviation Organization (ICAO) sets airlines' carbon emissions in the year 2020 as the ceiling of the total amount that will be legally allowed. Airlines that... 
Cars and trucks aren't the only source of transportation-related carbon emissions. The massive ships that ply the world's oceans are major sources of pollution as well, but generally receive less attention from regulators. But one cruise line is now taking steps to reduce the environmental impact of its fleet. DON'T MISS: Cruise ships start to... 
The energy sources used to generate grid electricity can be a major source of greenhouse-gas emissions, and thus they affect the environmental impact of electric cars. The cleaner the electricity used to charge an electric car, the cleaner that car becomes in operation. And among potential energy sources, hydroelectric power from dams would seem... ![Chris Grundler, director of EPA Office of Transportation and Air Quality [photo: EPA via Flickr]](http://images.hgmsites.net/tmb/chris-grundler-director-of-epa-office-of-transportation-and-air-quality-photo-epa-via-flickr_100568318_t.gif)
Current Corporate Average Fuel Economy standards require U.S. automakers to achieve a fleet average of 54.5 mpg (equivalent to roughly 40 mpg on the window sticker) by 2025. But who ensures that companies are actually complying with the CAFE mandate? As automakers work to meet stricter emissions standards, the little-known staff of regulatory... 
Right now, the debate over the future of Corporate Average Fuel Economy (CAFE) standards is in full swing. Today, they call for a fleet average of 54.5 mpg (or about 38 mpg on window stickers) by 2025 for vehicles sold in the U.S. But many within the auto industry—and those sympathetic to it—would like to see those standards rolled... 
It's now a year and eight days since the EPA broke the news that Volkswagen had admitted to including "defeat device" software in almost half a million so-called "clean diesel" vehicles sold in the U.S. from 2009 through 2015. That software detected when the cars were undergoing laboratory tests, and kept their emissions within legal limits during... 
It's been a year since the U.S. Environmental Protection Agency (EPA) revealed that Volkswagen used illegal "defeat device" software that allowed its diesel cars to cheat emissions tests. The VW diesel scandal may be just the beginning, though. Because while Volkswagen continues to negotiate with regulators and customers in the U.S., it seems that...
