Diesel is the Reason for the Sneezin’: Cleaner Holiday Deliveries are on the Horizon

Union of Concerned Scientists

How would that change if I hopped on the electric bus route at the end of my block? But while greenhouse gas emissions may be reduced, a delivery fulfilled by a diesel-burning truck may lead to increases in emissions of smog-forming nitrogen oxides and lung-damaging particulate matter.

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

Union of Concerned Scientists

This new regulation would apply to delivery vans, big rigs, box trucks, and buses. and nitrogen oxides (NOx) from the numerous commercial and government fleets of MHD vehicles in the state. Regulate more tractor trucks, including the smaller fleets.

Truck Loopholes 101 – When Emissions Regulations Don’t Match the Real World

Union of Concerned Scientists

The EPA is getting ready to finalize a critical regulation limiting emissions of smog-forming nitrogen oxide (NO X ) and soot (or particulate matter, PM 2.5 ) from new heavy-duty trucks. This is the first time EPA has sought to limit emissions in over two decades, and it is long overdue.

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.

Ask a Scientist: Gas Plants Disproportionately Harm Marginalized Communities

Union of Concerned Scientists

Gas, which now generates 40 percent of US electricity, is considered by some to be critical to maintain grid reliability. For example, Dominion Energy, an electric and gas utility in Virginia, is planning to build a mammoth 1,000-megawatt gas plant in an area with a high percentage of residents who are people of color and low-income.

Replacing California’s Oldest and Dirtiest Cars Will Save Money and Lives

Union of Concerned Scientists

As a result of continuing progress on regulations, the air-polluting emissions of new passenger vehicles currently for sale are thankfully much lower than those of older vehicles. These older vehicles are responsible for 73% of all nitrogen oxide exhaust from passenger vehicles and 64% of reactive organic gases.
