Changes to California’s Electric Truck Proposal Could Reap Huge Climate and Air Quality Gains

Union of Concerned Scientists

The ACF is an opportunity to deliver meaningful reductions in air pollution for the most affected communities, but the current proposal falls short of what is technologically and economically feasible. Moreover, CARB’s own research shows that this is both economically and technologically feasible.

Improving EPA’s Latest Ozone Transport Rule

Acoel

EPA’s latest proposed rule targeting NOx emissions from fossil-fueled electric generating units (EGUs) is a classic study of diminishing returns. The agency’s air quality modeling indicates that most areas would receive an ozone reduction of less than 0.1 enjoyed ozone reductions of 3 to 5 ppb or more. ppb by 2025.

EPA Grant Program Helps to Accelerate Transition to Cleaner Ports

Union of Concerned Scientists

The types of projects eligible under the CPP range widely, but notably the agency is focused on already proven zero-emission technologies, like electric tractor trucks, tugboats, and cargo handling equipment. The program is squarely focused on zero-emission equipment and projects – combustion technologies are explicitly ineligible.

DEP Awards $2.9 Million For Clean Diesel Transportation To Improve Air Quality

PA Environment Daily

Replacing heavy diesel vehicles with new low- to zero-emissions equipment technology will help mitigate air pollution from transportation sources.” Vehicles produce 47 percent of nitrogen oxides in the air, leading to the formation of ground-level ozone.

State Air Regulations Can Go Above and Beyond National Standards 

Legal Planet

States and local air quality regulators have the legal authority to set particulate matter (PM), ozone, and nitrogen oxides (NOx) emissions standards and adopt regulations for these pollutants when they are already in attainment of the national ambient air quality standards ( NAAQS ) set by the U.S.

Why UCS Supporters Are Pressing EPA to Let California Enforce Its Truck Pollution Rules

Union of Concerned Scientists

California’s leadership on reducing truck pollution has been on full display the past few years, passing critical regulations requiring 90 percent reduction in smog-forming nitrogen oxide (NO X ) emissions from diesel trucks and requiring manufacturers sell an increasing share of electric trucks to move away from fossil fuels altogether.

Good News—and Bad—about Fossil Fuel Power Plants in 2023 

Union of Concerned Scientists

With the clean energy transition already under way, the US electricity mix is set to continue changing this year. Solar power is expected to make up about half of all additions of US electric generating capacity in 2023, according to data from the US Energy Information Administration (EIA). I’ll start off with the good.
