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.

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.

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.

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.

Transportation is now the source of 28% of U.S. Before starting, here’s a little more background about the three cases: Texas v.
