The power grid that electric vehicles plug into will get cleaner over time. But depending on where you are, the rate at which it cleans up could have a lot to do with something that’s headed to the courts. A lawsuit filed Tuesday by 22 states and seven cities, in the United States Court of Appeals for the District of Columbia, aims to... States, Cities sue EPA over Clean Power Plan rollback
The power grid that electric vehicles plug into will get cleaner over time. But depending on where you are, the rate at which it cleans up could have a lot to do with something that’s headed to the courts. A lawsuit filed Tuesday by 22 states and seven cities, in the United States Court of Appeals for the District of Columbia, aims to... 
In the face of growing shortages of batteries and battery materials for electric cars, one respected analytics firm says those batteries would do more good for the environment put to use in more hybrid vehicles rather than fewer all-electric cars. Per kilowatt-hour of battery capacity produced and installed in plug-in vehicles, hybrids deliver 14... 
A new study published Wednesday in the journal "Nature" shows global warming has already accelerated far beyond what scientists anticipated. The study uses new methods to measure global ocean temperatures, which showed the oceans have retained 60 percent more heat than earlier estimates showed. Scientists measured the volume of oxygen and carbon... 
The EPA is planning to cancel the special waiver that California has relied on since 1970 to set its own emissions standards, according to a Bloomberg report. As part of its plan to reverse a program to steadily tighten fuel economy standards that it coordinates with California and the National Highway Traffic Safety Administration, the EPA has... 
EPA administrator Scott Pruitt would be controversial even if he hadn't flown to Morocco in December (first-class, on the taxpayer dime) to lobby the country on the benefits of liquified natural gas while living in a condo owned by a lobbyist for the country's largest LNG exporter. He is likely the first EPA head to axe scientists from the... 
Here’s some not-good news: After three years of minimal growth, global emissions of carbon dioxide are on the rise. So much so that we’re looking at new record highs, according to the Global Carbon Project. It's due largely to China burning more coal than it has in previous years. CHECK OUT: Global carbon emissions have been flat for... ![EPA administrator Scott Pruitt [photo from 2014]](https://images.hgmsites.net/tmb/oklahoma-attorney-general-scott-pruitt-2014_100584650_t.gif)
When top U.S. scientists released the fourth National Climate Assessment, it spelled out one blunt conclusion: human activity in releasing carbon dioxide into the atmosphere caused the climate change that has warmed the globe. Mandated for release every four years, the report will apparently have no sway over EPA administrator Scott Pruitt, a... 
Europe already has tough standards for reducing carbon-dioxide emissions in current and future vehicles. Now they're going to get significantly tougher between 2021 and 2030. At its weekly cabinet meeting, held Wednesday, the European Union formally adopted far more stringent requirements for reductions in vehicle emissions of carbon dioxide... 
When the Environmental Protection Agency quietly issued its new four-year plan in mid-October, the phrase "climate change" did not appear anywhere in the 38-page document. It is now clear the Trump Administration intends to delay, halt, or erase government efforts to limit U.S. emissions of carbon dioxide, the global-warming gas that is the main...
