CU has enhanced its ongoing carbon emissions inventory as part of its emissions reduction plan. CU–Boulder compensates for 10 percent of the campus’s electricity use by purchasing renewable energy credits. CU–Boulder has committed to spending an additional $50,000 per year for the purchase of renewable wind energy, and students, faculty, and staff can sign up to purchase wind power. In March 2007, CU–Boulder’s student government funded a $500,000 energy and climate revolving fund for energy projects in student-run buildings.
