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

Union of Concerned Scientists

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.

Ask a Scientist: UCS Transportation Program Adds Equitable Mobility to its Portfolio

Union of Concerned Scientists

In 1963, a typical car—which ran on leaded gasoline without pollution control devices— emitted 520 pounds of hydrocarbons, 1,700 pounds of carbon monoxide, and 90 pounds of nitrogen oxide every 10,000 miles traveled. Even so, cars and trucks are still making us sick—and killing us.

Reliance on Gas Power Plants Fuels Inequity

Union of Concerned Scientists

California recently extended , for the second time, the operations of three gas plants to 2026. Most notable of these polluting emissions are nitrogen oxides (NOx). Even as some parts of the country transition away from fossil fuel infrastructure, the retirement of gas plants has become another driver of inequity.

EPA: Power Plant, Pipeline, Cement, Paper, Glass And Other Industries In PA, Other States Face Tighter NOx Standards Under EPA’s Final Good Neighbor Rule

PA Environment Daily

Environmental Protection Agency announced the final Good Neighbor Plan , a rule that will significantly cut smog-forming nitrogen oxide pollution from power plants and other industrial facilities in 23 states.

Too Many Gas Power Plants are the Problem Not the Solution

Union of Concerned Scientists

gigawatts of capacity from gas plants are planned to go online from 2023 to 2026. But gas plants also release emissions of nitrogen oxides, more commonly referred to as NOx emissions, that contribute to smog and other pollutants. NOx emissions stick around locally, with major health consequences to nearby residents.

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.

Can California Stop Selling Polluting Cars by 2035? Yes It Can.

Union of Concerned Scientists

The Air Resources Board estimates that between 2026 and 2040, the ACCII rules will eliminate 69,569 tons of nitrogen oxides and 4,469 tons of particulate matter (PM2.5) , leading to over 1,200 fewer cardiopulmonary deaths due to air pollution. . The impact of the new rules goes beyond just lowering carbon emissions.
