The NYC Carbon Challenge for Multifamily Buildings

In 2013, New York City launched the NYC Carbon Challenge for Multifamily Buildings, engaging the City's largest residential property management companies to commit to reduce greenhouse gas emissions across selected buildings in their portfolios by at least 30 percent by making cost-saving energy efficiency improvements. To date, 22 New York City based residential property management firms have committed to the Challenge, pledging to reduce the greenhouse gas emissions from over 3,500 multifamily buildings over ten years. All together, these buildings represent over 275 million square feet, or 8 percent of the City's residential square footage. The residential sector accounts for 37 percent of New York City's total emissions, making up the largest single source of emissions in the city. In addition to reducing emissions, the energy efficiency and clean energy improvements that these buildings undertake will also help improve local air quality and increase resiliency to extreme weather events. Improving the energy efficiency of these buildings will also mitigate or reduce building operating costs, which is one of the key drivers of rising housing costs in New York City.
