Yosemite National Park
The seventh Climate Friendly Parks workshop was held at Yosemite National Park in April 2006. Visitors receive a strong message about reducing greenhouse gases (GHG) when they enjoy the free shuttle service on Yosemite National Park's hybrid buses. Operating since spring of 2005, the buses significantly increase fuel efficiency, and reduce particulate matter and nitrous oxide emissions. Benefits include an absence of exhaust smells and noise associated with the old diesel-only buses, along with reduced traffic in the park.
Established as a national park in 1890, Yosemite National Park (NP) rests in the Sierra Nevada Mountain Range, 150 miles east of San Francisco. The seventh Climate Friendly Park, Yosemite has implemented monitoring programs, conducted a visitor vehicle criteria air pollutant (CAP) emissions study, and purchased hybrid-electric buses in an effort to address CAP emissions. As Yosemite NP's efforts to reduce emissions broadened to include GHG emissions, the park also installed photovoltaic systems, solar cells, and fuel cells.
Yosemite NP's Environmental Management System, known as the Yosemite Environmental System (YES) program, has established YES teams that identified areas of environmental impact within the park. In the spring of 2004, The YES teams condensed these environmental impact areas into eight categories. Of the eight identified, three relate directly to Yosemite's GHG and CAP emissions. With 3.5 million visitors annually, the park is addressing greenhouse gas emissions seriously within the park and sharing its successes with visitors, Yosemite NP will help mitigate climate change far beyond its boundaries.
The Yosemite Criteria Air Pollutant and Greenhouse Gas Emissions Inventory was developed to provide an understanding of park emission sources and a baseline by which future emission reductions can be measured. The Yosemite Climate Action Plan includes this inventory and identifies the strategies the park intends to implement in order to achieve these reductions.
