The New York City Carbon Challenge

About the Challenge
Recognizing the existential threat that climate change poses to New York City and the world, Mayor Bill de Blasio has set the ambitious goal to reduce citywide greenhouse gas emissions 80 percent below 2005 levels by 2050. With Mayor de Blasio’s commitment, New York City reaffirmed its continued leadership in addressing global climate change. Because buildings account for nearly three-quarters of New York City’s emissions, the Mayor also released One City: Built to Last-Transforming New York City’s Buildings for a Low Carbon Future. The plan is a comprehensive, 10-year roadmap to improve the energy efficiency of the City's buildings, and sets an ambitious goal to reduce the city’s building-based emissions 30 percent by 2025 in order to be on the pathway to 80 x 50.

We know we can’t achieve our ambitious goals without the help of partners from the private sector. Since 2007, 17 of New York City’s leading universities, the 11 largest hospital organizations, 12 global companies, 20 residential management firms, and 19 hotels have accepted the NYC Carbon Challenge, pledging to voluntarily reduce their building-based emissions by 30 percent or more over the course of ten years.

The Carbon Challenge participants have moved aggressively to cut their energy use and emissions. In fact, 10 participants have already met the 30 percent goal, and 12 universities, hospitals, and commercial offices have expanded their commitment to a 50 percent reduction by 2025. All together, participants have cut their annual emissions by 175,000 metric tons of carbon and are collectively saving almost $175 million annually in lower energy costs. By the end of the program, current participants are projected reduce citywide emissions by nearly 510,000 metric tons of carbon dioxide equivalent.

The Carbon Challenge works by inspiring a high-level commitment within organizations, creating a platform for the exchange of information and ideas, and providing simple tools to track progress along the way. As they explore new ideas and opportunities to meet the Challenge goal, participants will also reveal effective strategies for energy efficiency that can be scaled up across New York City and beyond.
