Sustainable Slopes

Sustainable Slopes logo 2019

Adopted by the ski industry in 2000, Sustainable Slopes provides an overarching framework for ski areas on sustainability and enhanced environmental performance. Sustainable Slopes has two key parts - The Pledge for ski areas and the Skier Sustainability Code.

Approximately 200 U.S. ski areas have signed on to the Sustainable Slopes program, and have committed to incorporating sustainable practices into their operations.

For our member resorts: tools to help you achieve a sustainable operation.
