In 2007, President Michael S. Roth enthusiastically signed the Campus Leadership Campus Carbon Committment (previously the American College and University Presidents' Carbon Commitment), which committed Wesleyan to carbon neutrality by 2050. As part of this agreement, Wesleyan has:
- Wesleyan released its first Sustainability Action Plan (SAP) in April 2016. The SAP is a five-year plan that expands on the 2010 Climate Action Plan (CAP) and includes a greater focus on academics and social sustainability to move Wesleyan closer to carbon neutrality and create a sustainable campus.
- Wesleyan has completed annual greenhouse gas inventories since 2008.
- In October 2013, Wesleyan received a STARS (Sustainability Tracking, Assessment, and Rating System) Silver rating, STARS, a product of AASHE (Association for the Advancement of Sustainability in Higher Education), evaluates sustainability efforts and has been very influential in helping Wesleyan to set sustainability goals. In Spring 2014, Wesleyan released its first STARS Report.
- The College Sustainability Map, compares greenhouse gas inventory information from Wesleyan and all other ACUPCC signatory schools.
- Wesleyan maintains indoor air quality to OSHA and ANSI standards.
