About CORE

CORE is a 501(c)(3) nonprofit dedicated to leading the Roaring Fork Valley to a carbon-free, net zero energy future.

Under the guidance of a Board of Directors–made up of elected officials, utility representatives, and committed citizens–CORE helps people, businesses, municipalities, facilities and nonprofit organizations save natural resources and lower energy bills while reducing their carbon footprint.

This work is accomplished by providing grants, rebates and energy advising for residential and commercial energy upgrades, energy benchmarking for buildings, groundbreaking local projects, and climate action planning support for communities.

Since establishing a new tracking system in 2011, CORE has distributed nearly $10M in grants and rebates and prevented more than 29,721 MTe of carbon from being emitted into the atmosphere.

In 2000, CORE, the City of Aspen and Pitkin County worked together to form the nation’s first Renewable Energy Mitigation Program (REMP) as a revolutionary way to offset energy-intensive projects like large homes and snowmelt systems. Funding for CORE initiatives comes from a combination of REMP funds, local governments, private donations and grants. To learn more about the REMP program, visit the City of Aspen or Pitkin County’s websites. 

The organization was built on the principle that problems the size of a global climate crisis require local innovation to overcome. CORE’s impact on the Roaring Fork Valley’s climate and economy continues to grow as large-scale, mission-driven projects like community solar planning and methane capture for abandoned coal mines are added to the repertoire of climate-saving initiatives.

Giving Thought: Collaboration at the heart of addressing the climate crisis

The Community Office for Resource Efficiency (CORE), a local non-profit, believes that effectively taking on a problem the size of the climate crisis requires innovation and collaboration at a local level to overcome.

Hopeful Huts

CORE (Community Office for Resource Efficiency) conducted an energy assessment of the 10th Mountain’s employee housing unit in Aspen, providing $36,000 in rebates for a PV solar system, mini-split heat pumps, and air sealing/insulation, which will lower the building’s carbon emissions.
