Production of the gift itself and packaging contribute to pollution, however, I wanted to better understand this “last-mile” delivery impact. How would that change if I hopped on the electric bus route at the end of my block? Would the footprint of my choices be greater if I shopped online versus driving to a local store?

California recently extended , for the second time, the operations of three gas plants to 2026. Air pollution Gas-fueled power plants and compressor stations release emissions that pollute local air and have dangerous health impacts to nearby residents.

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. Soon thereafter, it began extolling the virtues of battery electric vehicles , which it continues to do today.

cranks its air conditioners to get through historic high temperatures , the need for energy that slows, not hastens, climate change is more apparent than ever. Yet, in 2022, almost 40% of electricity in the US was generated by power plants fueled by natural gas. States remain widely varied on their reliance on gas for electricity.

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.

California’s air pollution regulator, the Air Resources Board, is poised to adopt one of the most important steps that the state has ever taken to reduce exposure to air pollution and limit climate changing emissions. First is stricter smog-forming pollution rules for conventional cars.

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.
