JHU has committed to reducing emissions 51 percent below 2008 levels by 2025, and has reduced emissions by 17,000 tons over three years despite campus growth. The Sustainable Hopkins Infrastructure Program funds campus efficiency projects, and the university has several peer-to-peer education programs to encourage behavioral change. Efficiency initiatives include the installation of 20 megawatts of cogeneration facilities, lighting and equipment upgrades, building occupancy schedule adjustments, temperature setbacks, and peak demand management.
