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... Are regulators focusing too much on EV sales and not enough on retiring ICE vehicles?

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... 
Putting bigger battery packs in EVs can boost range, but a new study suggests it could also lead to a major increase in particulate emissions—from tires. The study comes from Emissions Analytics, a U.K.-based independent emissions testing firm. It first began sounding the alarm in 2020, publishing a study showing that tire-wear particulate... 
Mass adoption of electric vehicles is proceeding slowly, but one way to reduce greenhouse gas emissions today could be addressing poorly timed traffic lights, the traffic data analysis and controls firm Inrix claims. The company is hawking an analytics tool it claims will allow traffic agencies to run their networks of stop lights more... 
On Friday, the National Highway Traffic Safety Administration finalized tougher fleet fuel economy standards for vehicle fleets that will mean an adjusted, industry-wide average of about 49 mpg across new passenger vehicles and light trucks in 2026. The standards, which are a step steeper than the administration’s original proposal, boost... 
Major automakers are siding with the EPA in a court battle over tougher emissions standards, Reuters reported Wednesday. Texas and 15 other states, along with ethanol groups, have challenged the EPA's emissions rules under the Biden administration, which aim to reinstate tougher rules after a rollback by the previous administration. The Alliance...
