CORE is a non-profit organization whose work in carbon reduction is funded by the Renewable Energy Mitigation Program known as REMP. In 2000, CORE, the City of Aspen and Pitkin County launched this groundbreaking carbon fee program— the first of its kind in the world — to mitigate the environmental impacts and greenhouse gases produced by large homes and energy-using systems. CORE distributes the REMP funds in the form of rebates and grants with oversight from the City and County. Since the program’s inception, we have awarded more than $8.2 million in REMP funds to the community.

How REMP Works

REMP is part of Aspen’s and Pitkin County’s Energy Code that applies to new construction and large remodels.  Under REMP, homeowners and commercial property owners who choose to install energy-using systems such as snowmelt, outdoor pools, spas, or large square footage have the option of installing a renewable energy system on site, or choosing a mitigation payment option instead. Those payments become the pool for CORE rebates and grants.
