WASHINGTON (AP) — The government has found that jet engine exhaust is adding to climate change and endangering human health, and needs to be regulated.
The Environmental Protection Agency announced Monday that it will use its authority under the Clean Air Act to impose limits on aircraft emissions.
Jet engines spew significant amounts of greenhouse gases including carbon dioxide and methane into the upper atmosphere, where they trap heat from the sun. But proposed regulations such as imposing fuel efficiency standards have faced stiff opposition from aircraft makers and commercial airlines.
A U.N. panel in February recommended new emissions standards for international flights starting in 2020. The EPA finding announced Monday will likely result in similar limits on domestic carriers.
Aviation accounts for about 5 percent of global greenhouse emissions.
