Aspen’s Greenhouse Gas (GHG) Reduction Targets

Since 2004, Aspen has compiled GHG inventories at regular intervals. Tracking GHGs provides insights about whether we are moving in the right direction, and which initiatives have been most effective. Government operations GHG inventories are compiled annually and community-wide inventories are published every 3 years. This tracking has revealed that:

Climate Action Planning

Understanding what’s worked and what hasn’t sets the context for deploying new initiatives and strengthening existing ones. In collaboration with a diverse group of community stakeholders, the City of Aspen is updating Aspen's Climate Action Plan (CAP). Aspen’s original CAP covered the years 2007 through 2009 (view this plan document (PDF)). Aspen’s new CAP (anticipated publication date December 15, 2017) covers the years 2018 through 2020 and was compiled with input from numerous community stakeholders.


The GHG Reduction Toolkit

In partnership with the Community Office Resource Efficiency, Aspen published the GHG Reduction Toolkit (PDF) in late 2017. Culminating a year-long effort with subject matter experts and organizational leaders, the Toolkit is a comprehensive resource for municipalities interested in reducing GHGs while generating a host of co-benefits. Aspen’s 2018 CAP draws priorities from the Toolkit and future CAP updates will likely continue to do so.
