emissions

And electric SUVs don't solve the problem. Additional CO2 emissions from SUVs in 2022 overshadowed the increased sales of electric vehicles.

Tires and brakes are the source of 52% of road-vehicle particulate emissions, say researchers.

In an unusual instance of industry speaking up for stronger regulations, a handful of automakers are testifying with California.

Such an incentive would fit in for California, which plans to ban gasoline vehicles without charge ports by 2035 but doesn't have a cohesive plan for retiring existing gasoline models.

Enforcement for any polluters will take the form of California's DMV denying new registrations to non-compliant vehicles, auditing, and issuing fines.

A proposal from the EPA for 2023-2025 may result in wider production and use of ethanol, but it also may help utilities produce cleaner energy for EVs.

Russia's invasion of Ukraine and the resulting economic uncertainties have accelerated the timeline—leading to more spending on renewables, cleaner EVs, and a "historic turning point," the authority anticipates.

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.

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

The EPA recently announced the levying of millions of dollars in fines against companies for selling equipment designed to circumvent pollution controls, illegal under the Clean Air Act.

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

The automakers face off versus a coalition of 17 state governments opposing a significant portion of the auto industry and rallying for greater emissions

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.
