Visitors to national parks expect clean air and clear panoramic views of our natural and cultural landscapes. Most pollution originates from outside the park and is created by wildfires, power plants, oil and gas development, and automobile emissions.
Glacier National Park is a Class I NPS area under the Clean Air Act which affords the park the highest level of air quality protection. In order to reduce the effects of air pollution in the park, air quality studies and monitoring programs at Glacier focus on contaminants such as mercury, nitrogen, sulfur, ozone, fine particles, and haze to assess status and trends. Park personnel work with federal, state, and local agencies, industry and the public to develop plans to reduce air pollution and protect resources within the park. The use of shuttle buses to reduce fuel use and emissions, improved energy conservation measures in park facilities, and increased public education are all steps being taken to continue to improve air quality in Glacier which at the same time improves experiences for visitors and staff.
