The Challenge

The City of Aspen is planning and preparing for a different climate in the future. What we know:

  • Our climate is changing and will continue to change.
  • These changes affect Aspen’s community, visitors, environment and economy.
  • The spectrum and severity of changes we will see depend on our actions as a City and community, now and going forward.
  • We need to both prepare for the coming impacts of climate change, and reduce our ecological footprint now.

What is Climate Resiliency?

Preparing for climate change impacts by reducing our exposure to future risks while strengthening our capacity to respond is referred to as “climate resiliency.” Our preparations will benefit the community now and in the future.


Aspen's climate is already changing and will continue to do so. The City worked with the Aspen Global Change Institute to understand how anticipated changes are likely to affect ecosystems, recreation and tourism, public health and safety, the built environment and infrastructure, and energy and water. Climate Change & Aspen reports published in 2006 and 2014 detail likely climate impacts accompanied by adaptation strategies in key sectors.
