This Washington, D.C., campus has big goals: planning to achieve carbon neutrality by 2020 and eliminate campus greenhouse gas emissions. Working with George Washington University and its hospital, American University recently entered into an agreement to source half of the school's electricity from renewable power. This is the largest non-utility solar photovoltaic (PV) power purchase agreement in the United States. Half of AU's electricity will be direct, grid-delivered solar power. Using direct solar power for half of the campus electricity needs will eliminate 15,000 metric tons of carbon dioxide from the atmosphere each year — equal to taking 3,000 cars off the road. The school also has a Green Teaching Certification Program to reward faculty members for incorporating sustainability content into their classrooms.
