gigawatts of capacity from gas plants are planned to go online from 2023 to 2026. Because unlike moving sources of air pollution like cars, gas plants are completely stationary. But gas plants also release emissions of nitrogen oxides, more commonly referred to as NOx emissions, that contribute to smog and other pollutants.

By 2032, new light-duty vehicle climate emissions would decrease by nearly 50 percent (to 85 grams/mile) compared to existing standards that go through 2026. Air quality and public health But climate pollution isn’t the only thing coming out of tailpipes that’s harming us, and the impact of these tailpipe emissions isn’t equally shared.

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.

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.

EPA considering a range of alternatives EPA proposed standards that would aim to reduce greenhouse gas tailpipe emissions by about 70 percent compared to today’s vehicles (or about a 60 percent reduction from the 2026 standards currently on the books), to a lab certification level of emissions of 82 grams per mile (g/mi) by 2032.

While EPA has projected gasoline vehicles to improve by close to 20 percent between now and 2032 in order to meet its standards, largely the result of standards already on the books through 2026, this could and must be closer to 30-35 percent to be consistent with our urgent need to address climate change.

The transportation sector is also a substantial source of nitrogen oxides and particulates, both of which are dangerous to human health. Transportation is now the source of 28% of U.S. greenhouse gas emissions, more than the electric power sector.
