Watch allies explain why clean air is important to them.

Air pollution is among the most serious threats facing national parks. Dirty air can darken the horizon and ruin scenic views. It is also harmful to plants, fish, and other wildlife, and even affects the health of visitors and park staff. Most of the air pollution affecting national parks results from the burning of fossil fuels, especially by coal-fired power plants.

NPCA advocates for strong and fair enforcement of existing laws and regulations that protect our parks and lungs from pollution. Thanks to NPCA’s ground-breaking consent decree, we now have the opportunity to reduce park-polluting haze throughout the country using the Clean Air Act’s protections for visibility. We are also taking steps to defend America’s national parks from ill-conceived proposals to build new coal-fired power plants near the parks. In addition, NPCA works to identify areas where new regulations may be needed to ensure that the parks—and the people who love them and live near them—have clean, healthy air.
