National parks have an undeniable environmental impact on the very lands they seek to preserve. Yellowstone’s managers have been working on ambitious management goals to elevate it to be a world leader in environmental stewardship and become one of the greenest parks in the world by 2016.

The Yellowstone Environmental Stewardship (YES) Initiative goals (against a 2003 baseline) are to reduce greenhouse gas emissions by 30 percent (50 percent by 2025); reduce both electricity and water consumption by 15 percent; reduce fossil fuel consumption by 18 percent; and divert all municipal solid waste from landfills.
