When you donate to CORE, you champion community health and resilience. You help us bridge the gap between aspiration and action, empowering everyone to reduce their energy consumption. This leads to cleaner air and water, lower energy costs, and a stronger local economy for generations to come.
In 2024, CORE advanced 145 projects that lower carbon emissions in the built environment. We awarded nearly $1 million in grants, rebates, and assessments to make these projects happen and change the landscape of our community.
We make sure that your contributions toward sustainability stay here in your own backyard, leaving a lasting legacy for generations to come.
Donate today to fund immediate climate action, curb the pace of climate change, and protect the beauty and viability of our precious home. You can make a one-time gift, or streamline your giving with a recurring monthly donation.
"We need people to to see CORE as one of the pivotal organizations of our time - an organization that has the potential to save the planet."
- Bill Stirling, CORE Founder & Former Mayor of Aspen
CORE founder and long-time board member, Bill Stirling, devoted 30 years to CORE, our community, and the environment. He represents altruism, giving back, and making climate action possible for everyone, for a better tomorrow.
The Stirling Giving Society honors Bill’s legacy and gives CORE a platform to recognize our most loyal donors, allowing us to continue the work Bill started. With a gift of $2,500 or more, you can be a part of this high-level network of donors that provides CORE with the essential support needed to conserve our region’s natural resources, cut carbon emissions to mitigate climate change, and continue the work that Bill started.
