A brief description of the institution’s GHG emissions reduction initiatives:

As of January 1st, 2020 Colorado College reached its goal of Carbon Neutrality. In the first four years, as directed by the Sustainability Plan drafted in 2009, Colorado College reduced carbon emissions by more than 20% and saved $1.74 million in utility costs. Utilities management at Colorado College has become an area of increased emphasis. In FY13 CC experienced continued success in decreasing energy use and costs campus-wide. Cumulative avoided costs for utilities are estimated in excess of $5.7M since the 2008 baseline. Recent and notable accomplishments include: hiring of a full-time on Campus Energy Manager; developing the Carbon Neutrality Plan through collaboration between the Office of Sustainability, Facilities Services, and the Campus Sustainability Council; increasing renewable energy purchases via wind from Colorado Springs Utilities and solar from SunShare; introducing Sofame Heat Recovery at the Central Heating Plant, the building of various solar arrays on buildings around campus including the dean's house, Synergy house, Gaylord Apartments, The Worner Center, El Pomar Center, and Cornerstone Arts Center. The Dean's house and Synergy House are now net-zero buildings.

As of January 2015, LED lights were installed in the Honnen Ice Arena which resulted in 75% energy reduction and annual carbon savings of 100 MTCO2. In May 2015, LED lights were also installed in Schlessman Pool, resulting in 75% energy reduction and annual carbon savings of 40 MTCO2.
A water conservation project including pipe repairs at Schlessman Pool was completed in 2017. It resulted in savings of 4.1 million gallons of water saved from 2015 to 2016.
Numerous improvements have been made across campus in machine efficiency, ranging from instruments in Barnes to the steam generator in our campus cogeneration plant. Real-time energy dashboards accessible for the public were completed.
In 2018, Colorado College acquired the neighboring Fine Arts Center, which increased GHG emissions. Audits and commissioning are in the works, and RECs were purchased in 2017. Colorado College also completed renovations to Tutt Library. Tutt Library is powered using geoexchange and is a net-zero building that sets a national precedent for sustainable libraries.

The greenhouse gas inventory includes Colorado College's main campus, the Florissant CC Cabin, and the Baca Campus at Crestone, Colorado. Properties owned by the College but managed by external entities were excluded from the inventory, because the College is not responsible for the occupancy or maintenance of utilities for the associated buildings.
