The program offers $3,000 to Vermont residents who retire an operational vehicle deemed to be high-polluting that is at least 10 years old, and switch to a new or used EV.

While New York, Washington, Oregon, Massachusetts and others have signed on, Minnesota is a maybe and Virginia's governor is reportedly calling the policy "ludicrous."

The diesel ban would apply to all new medium-duty and heavy-duty commercial trucks sold in California beginning in 2040, with some exceptions for certain emergency vehicles.

GM and the Environmental Defense Fund asked the EPA to develop emissions standards yielding a 60% reduction in greenhouse gas emissions by the 2030 model year.

Natural rubber from guayule could offset the oil, silica and virgin carbon black currently used in tires.

States that follow California emissions rules represent about a third of the U.S. auto market, and they each may also adopt the new targets.

California sets more aggressive emissions standards and electric vehicle targets, and it's joined in doing so by a growing group of states.

Significant "turnover lag" between the start of new EV sales regulations and the retirement of internal-combustion vehicles could get in the way of ambitious goals, researchers argue.

The assurance that your EV will keep getting cleaner and more climate-friendly with the grid—everywhere in the U.S.—is no longer a foregone conclusion.

The more electricity EVs consume from a dirty grid, the bigger their carbon footprint; EV efficiency is important.

The state's hydropower generating capacity is nearly half that of normal conditions, forcing California to rely on more carbon-intensive sources for a greater amount of its grid mix

Even though EVs use the friction brakes less, some data suggests they generate more brake dust—and the EU is looking to contain that.

Emissions Analytics performed chemical analysis of hundreds of new tires and now concludes tire-wear particulate emissions are 1,850 times greater than tailpipe particulate emissions.

Well-timed signals can have a significant impact on emissions—equivalent to the CO2 absorbed by a forest 3.3 times the size of Atlanta, according to Inrix.

The mpg standards are a step steeper than an original proposal. Arriving at an effective 49 mpg, they boost fleet efficiency by 8% to 10% annually for model years 2023-2026.

It's been a long time coming. Enforcement had been delayed after automaker lobbying, triggering a lawsuit from California.

Coal accounted for 40% of the overall increase in global CO2 emissions in 2021, according to the IEA—a factor affecting electric vehicles' overall impact.

Producers argue that the new rules exceed the EPA's authority because they effectively force automakers to produce electric cars

Environmental groups claim the EPA's proposed standards should do more to encourage deployment of electric trucks.

Relatively simple strategies like smart charging and time-of-use rates will help smooth utilities' loads and get the most from renewables.
