Polluted Parks: How America is Failing to Protect Our National Parks, People and Planet from Air Pollution

Nearly every national park is affected by air pollution and climate change in adverse ways. NPCA’s “Polluted Parks” report evaluates damage from air pollution at 417 national parks based on harm to nature, hazy skies, unhealthy air and climate change. It also presents stories of people affected and clear and feasible solutions to benefit our air, parks and climate.

of national parks are plagued by significant air pollution problems


Oil and gas production emits pollutants that harm our air and exacerbate climate change. The administration’s proposal to rollback methane pollution rules would increase emissions by more than 40 percent.


Federal and state governments must hold polluters accountable by advancing and strengthening regulations that require sharp reductions in air pollution from oil and gas development.

of national parks suffer from haze pollution


Coal plants muddy skies in our national parks from Rocky Mountain to Big Bend. Power plant pollution also drives climate change and can harm people and wildlife.


The administration must end its efforts to rollback and rewrite air and climate rules that favor industrial polluters over people and our planet. Instead, it should implement our nation’s clean air laws.

During the last two years, the Trump administration has systematically undermined sound science and the role of scientists in policy and rulemaking.


The administration and Congress must restore and safeguard unbiased science in the foundation of health and environmental policies.

of national parks have air that is unhealthy to breathe at times


National parks and wilderness areas suffer from haze pollution that chokes off incredible views in our national parks.


EPA must abandon efforts to excuse polluters from contributing to regional haze and instead prioritize cleaning and clearing up the air at protected public landscapes.

of national parks are significantly threatened by climate change


The Trump administration is dismantling commonsense rules that limit greenhouse gas pollution and withdrawing the U.S. from the Paris Agreement — the global climate treaty aiming to cut pollution and move to clean energy.


Congress must swiftly enact legislation to significantly cut U.S. climate emissions by 2030 and preserve and implement rules to reduce carbon and methane pollution to get our nation’s climate policies back on track.
