Seven years after the Volkswagen diesel scandal began, emissions "defeat devices" are still a problem, but it's mostly aftermarket companies that are drawing the attention of regulators. The EPA recently announced the levying of millions of dollars in fines against one company, and potential fines for another, for selling equipment designed to... 
California is taking a big step toward a goal of ending new internal-combustion vehicle sales by enshrining the planned 2035 end date as policy. Governor Gavin Newsom signed an executive order in September 2020 calling for a ban on the sale of new gasoline and diesel cars by 2035. On Thursday, the California Air Resources Board (CARB), the... 
Toyota has finally ended its fight with California, recognizes the state's authority to set its own, more aggressive emissions standards through the California Air Resources Board (CARB) under the Clean Air Act. The automaker said Wednesday that it had communicated this to CARB and the California state government. "In our recent communication, we... 
Global EV sales are steadily increasing with help from regulators, but that won't matter if existing gasoline and diesel vehicles aren't retired quickly, new research argues. "The slow speed of fleet turnover presents a substantial barrier to deep decarbonization," researchers state in a new book on energy transition (via Axios). Researchers... 
Electric cars are only as clean as the grid they plug into, and the emissions from using your EV will keep dropping over the years you use it because the grid keeps getting cleaner. It’s a point we emphasize regularly, and after Thursday’s Supreme Court ruling, the assurance of a cleaner grid over time, everywhere, is no longer a... 
Electric cars don't produce "tailpipe" emissions, but their overall carbon emissions are not zero. It's time for federal efficiency standards to reflect that, argues the American Council for an Energy-Efficient Economy (ACEEE). The majority of EVs get their electricity from the grid, which in the United States is still 60% fossil-fueled, the group... 
Five automakers have filed a motion to intervene on the side of the EPA, against a legal challenge to California's ability to set its own stricter emissions standards. In a joint statement, BMW, Ford, Honda, Volkswagen, and Volvo asked a federal court to uphold the EPA Decision Waiver giving California the ability to set emissions standards... 
A California drought will increase the carbon footprint of electricity used to charge EVs, according to a new report from the Energy Information Administration (EIA). The drought has cut the state's hydropower generating capacity nearly in half compared to normal conditions, forcing California to rely on more carbon-intensive sources for a greater... 
Tailpipe emissions tend to be the focus of regulators, but the next round of European Union emissions standards will tackle pollution from another source—one that is particularly relevant to EVs. Scheduled to be unveiled in July, the upcoming Euro 7 standards will still require automakers to reduce tailpipe emissions such as nitrogen oxide...
