Columbia University advanced its strategy for clean, renewable energy with a purchase of renewable energy certificates (RECs) for off-site wind generation, continued use of hydropower, and new investment in solar power. As a result, Columbia achieved 100% renewable, zero emissions for reported electricity in 2018 for the Morningside, Manhattanville, Irving Medical Center, Lamont-Doherty Earth Observatory, Nevis, and Baker Athletics Complex campuses. With a 47% reduction in absolute GHG emissions at the Morningside campus, Columbia has exceeded its goal of cutting emissions by 35 percent over 2006 levels by 2020.
