A look in to NYU's new sustainable effort: the CoGen plant. CoGen is the cornerstone of NYU’s 2010 Climate Action Plan (CAP), a comprehensive approach to reducing the University’s carbon footprint and enhancing its overall sustainability. NYU’s CAP was spurred on in part by the signing of Mayor Bloomberg’s PlaNYC Climate Challenge, which calls on all city colleges and universities to voluntarily reduce greenhouse gas emissions by 30 percent by 2017. Prior to the CoGen upgrade, NYU had made significant progress in reducing its greenhouse gas emissions, cutting them by 20-25% over just four years, from a peak of ~179,000 Metric Tons Carbon Equivalent (MTCE) in 2006 to ~125,000 MTCE in 2010. With the addition of CoGen coming on line, NYU’s total emissions are expected to drop approximately 20% more, to about ~98,500 MTCE. This not only fulfills the Mayor’s Challenge, but surpasses it by an additional ~10% reduction in greenhouse gas emissions, reaching a total of ~40%.
