EPA Office of Air and Radiation Administrator Bill Wehrum, an attorney who formerly represented power companies in their effort to roll back clean-air regulations, has resigned. The biggest air-quality issues that the Office of Air and Radiation oversees are tailpipe emissions from cars, and emissions from power plants that increasingly provide... 
Americans driving more miles could cancel out emissions progress. Airbus looks to build hybrid airplanes. China puts restrictions on who can build electric cars in the world's largest EV market. And Jaguar plans to launch its new flagship XJ sedan as an electric. All this and more on Green Car Reports. Jaguar Land Rover plans to introduce its... 
New York City's efforts a decade ago to clean up pollution from old taxi models has worked—mostly—a new study shows. The study, by researchers at the Columbia University Mailman School of Public Health (in New York) and Drexel University, and published in the Journal of Exposure Science & Environmental Epidemiology, shows that the... 
Today, the EPA acted on a proposed change to expand the amount of ethanol that can be mixed into pump gasoline from June 1 to September 1. In an official announcement, the agency made no comment about how the move might affect summer air quality or pollution issues. The EPA said that it “delivers on President Trump’s promise,”... 
The EPA is following through on plans to reduce the number of deaths it counts as attributable to air pollution, reportedly in an effort to support the Trump Administration's plans to shore up the coal industry. The plans were first discussed at a meeting of a key EPA air-quality standards board in the end of March. Now a report in the New York... 
As virtuous as one might be in choosing a vehicle that doesn’t produce tailpipe emissions, there’s a hazy reality to traveling by car: That you’re stuck breathing emissions from other gasoline or diesel vehicles—especially fine particulate emissions, which are some of the most concerning for health and tend to linger within... 
As Washington waffles on developing a Green New Deal—or works to torpedo it altogether—LA's environmentalist mayor, Eric Garcetti, signed off on a local Green New Deal for the city on Monday. “Politicians don’t need to look across the aisle to find the answers—they need to look across the country,” he said, in...

Every year, as Earth Day rolls around, we survey the automotive landscape looking for progress in the industry's efforts to reduce emissions and limit global warming. We've identified a lot of progress recently. More than a dozen new electric models are set to go on sale in the coming year, and sales of plug-in models more than doubled in the past... 
We had a first chance to drive the new 2020 Kia Soul EV. London's new pollution charge on older vehicles makes it really expensive to drive older cars into the city. And our latest Twitter poll asks what GM should do with the Volt name now that it no longer produces the car. All this and more on Green Car Reports. First announced in 2017, the city... 
It isn't just global warming emissions that the EPA plans to deregulate. At a meeting last Thursday, a key air quality standards board at the agency cast doubt on longstanding findings that particulate matter—the microscopic particles spewing from diesel tailpipes—can cause health problems leading to premature deaths. In the absence of...
