NYC’s 2023 benchmarking data is here! See how building energy use is changing.

Updated with latest data December 2024

More than a third of New York City’s greenhouse gas emissions come from buildings over 25,000 square feet. Thankfully, NYC has been collecting data about the energy and water used by these large buildings—referred to as benchmarking data—since 2010. This data allows us to analyze how buildings are using energy today along with changes over time.
