Re: Comments on Reconsideration of 2009 Endangerment Finding and Greenhouse Gas Vehicle Standards (Docket ID No. EPA–HQ–OAR–2025–0194)
Dear Administrator Zeldin:
On behalf of Appalachian Mountain Club, the Coalition to Protect America’s National Parks and National Parks Conservation Association, we submit the following comments strongly opposing the Environmental Protection Agency’s (EPA) proposed Reconsideration of the 2009 Endangerment Finding and Greenhouse Gas Vehicle Standards (Proposal).
Collectively, our organizations represent the interests of America’s most beloved public lands and treasured natural and cultural resources. These public lands and cultural sites offer wondrous beauty, recreational opportunities, ecosystem services, and historic preservation, while providing experiences that improve visitors’ health and support local economies.1Danielle Buttke, Diana Allen, and Chuck Higgins, Benefits of Biodiversity to Human Health and Well-Being, 31 Park Science (2014), https://perma.cc/HQC2-4VTK, (“Benefits of Biodiversity”) (Attached as Ex. 1). 1
We are particularly concerned about the impacts of climate change and air pollution on our national parks, national forests and other federal public lands, and how the proposal could permanently end all federal efforts to mitigate greenhouse gas (GHG) pollution. America’s public lands, especially its national parks and forests, are among the places most endangered by climatic change, which is driven by greenhouse gas pollution.
