California is using the growing sums of money it receives from its emission cap-and-trade auction for good, including to tackle up some of the state's most egregious transportation polluters. In mid-December, California announced it would invest $663 million in a plan to clean up particularly dirty fleets, especially those operating in low-income...

California is using the growing sums of money it receives from its emission cap-and-trade auction for good, including to tackle up some of the state's most egregious transportation polluters.

For 45 years, the Environmental Protection Agency has been charged with protecting the U.S. from pollution in its air, water, and land. Under the Trump Administration, its administrator Scott Pruitt is aggressively muzzling and removing scientists, eradicating climate-science from its activities, and eliminating dozens of regulations. That makes... 
With China mulling an eventual ban on sales of cars with gasoline or diesel engines, the world's largest car market made it clear earlier this month that it intends to force a conversion to zero-emission vehicles. Now California, which has led the U.S. in environmental awareness and emission reduction for decades, is doing the same. Governor Jerry... 
Continuing political turmoil and news coverage of the Trump Administration haven't stopped the president's agency heads from drastically reshaping policies on energy, the environment, and emissions. Comments are now being taken on the reopened EPA limits on vehicular carbon emissions for 2022 through 2025, although reporters had to dig to find out...

As rules to boost fuel economy and lower carbon emissions in vehicles around the world continue to stiffen, acronyms like EREV, CNG, and MPGe are becoming more and more common. Ever wonder what they all mean? This glossary is your chance to enter a veritable Twilight Zone of terminology--and find out, say, whether a PZEV is related to a PHEV... ![Chevrolet Bolt EV being charged outside Go Forth electric-car showroom, Portland [photo: Forth]](http://images.hgmsites.net/tmb/chevrolet-bolt-ev-being-charged-outside-go-forth-electric-car-showroom-portland-photo-forth_100606247_t.gif)
It's clear that incentives to buy specific cars work best when they can be applied directly at the time of sale. That's why purchase rebates are widely preferred by electric-car advocates to tax credits, which may take up to 15 months to be usable, depending on the timing of the purchase and tax filing. While the federal electric-car incentive is... 
The sales growth of electric cars has made strides in recent years, and California's Zero-Emission Vehicle mandate has more than a little to do with that. The program adopted by the state of California more than 20 years ago, and much modified since then, requires that carmakers sell a certain number of zero-emission models in California and 10... 
The challenges of building fueling infrastructure for passenger cars powered by hydrogen fuel cells are well known by now. Toyota, Honda, and Hyundai now lease low volumes of fuel-cell vehicles in selected areas of California where a few dozen hydrogen fueling stations are now up and running. The challenges for fueling may be less daunting for... 
The California Air Resources Board voted Friday to confirm its stricter emissions standards for 2025, setting up a potential clash with the Trump Administration.
