NYC Carbon Challenge

View of New York City buildings

The NYC Carbon Challenge is a voluntary leadership initiative and public-private partnership between the Mayor's Office of Climate & Environmental Justice and leaders in the private, institutional, and non-profit sectors who have committed to reduce their greenhouse gas emissions by 30% or more over ten years. The Mayor's Office provides support, resources, and recognition as participants pursue different energy efficiency improvements, efficient on-site generation, and sustainability initiatives.

Over 125 participants have taken the NYC Carbon Challenge pledge, including the City's largest universities, hospitals, commercial owners and tenants, residential property management firms, hotels, and retail organizations.21 participants have already met the 30 percent goal, and 19 universities, hospitals, and commercial offices have expanded their commitment to a 50 percent or greater reduction by 2025. Others have made even greater commitments: during Climate Week 2021, 13 leading participants have committed to achieving Carbon Neutrality in select buildings within their NYC portfolios by 2030. Partners in this program expansion include Barclays, Credit Suisse, Deutsche Bank, Empire State Realty Trust Inc, Google, InterContinental New York Barclay, JB&B, Lowes Regency Hotel, Marion Scott Real Estate Inc, RiseBoro Community Partnership, StuyTown Property Services, The Westin New York at Times Square, and Yeshiva University.

Altogether, participants have cut their annual emissions by more than 600,000 metric tons of carbon and are collectively saving over $200 million annually in lower energy costs. By the end of the program, current participants are projected to reduce citywide emissions by nearly 1,500,000 metric tons of carbon dioxide equivalent– the equivalent of taking more than 300,000 cars off the roads – and result in an estimated $700 million in energy cost savings.
