All Buildings By Greenhouse Gas Intensity

These are the Chicago's benchmarked buildings that reported the highest greenhouse gas intensity i.e. emissions per square foot. Large, efficient, buildings can perform much better than very inefficient small buildings on this metric.

Note: Data From Large Buildings in 2023

Note: This data only includes buildings whose emissions are reported under the Chicago Energy Benchmarking Ordinance. According to the City “As of 2016, this list includes all commercial, institutional, and residential buildings larger than 50,000 square feet.”

The latest year of data is from 2023, but we update the site regularly when new data is available, and some buildings may have failed to report that year, and only have older data available.

Additionally, note that all tons specified are metric tons.
