Air pollution is among the most serious threats facing national parks, threatening visitors’ health, clouding scenic vistas and altering our climate. To restore clean air to national parks, we work to defend the clean air laws that protect them.
Air pollution threatens the health of parks’ visitors, ecosystems and surrounding communities, while cutting miles and miles off of scenic views. Most of the air pollution affecting national parks results from the burning of fossil fuels, especially by coal-fired power plants and oil and gas development, but vehicles and agricultural and industrial emissions are also contributors.
Ozone pollution is one of the most problematic sources of dirty air in our national parks. Fortunately, in 2016, the Environmental Protection Agency strengthened the ozone pollution standards based on scientific evidence that lowering the standard to 70 parts per billion is necessary to protect people, plants and wildlife. Sadly, though, these new standards are now at risk. The administration and Congress are attempting to significantly delay and weaken these standards through various legislative and administrative attacks. Moreover, some of these attacks would go even further to weaken the Clean Air Act itself, undermining the frequency of review and strength of setting such safeguards for ozone and other pollutants.
National Parks Conservation Association works every day to protect, defend and ensure implementation of these clean air protections to deliver critical improvements to air quality in our national parks and surrounding communities. We also work to guard park air from the threats of new pollution sources and to forward new clean air and climate policies that will help make our park’s air healthy and clear.
