Top 50 Buildings by Greenhouse Gas Emissions
These buildings are the biggest emitters of greenhouse gases in Chicago, both directly (like by burning natural gas on site for heating) and indirectly (by using electricity that is still produced with some fossil fuels).
Many of these buildings are very large, which is a big part of why they use so much energy and have such high emissions. Several of these buildings, however, are not that large, but are instead incredibly inefficient - they use a lot of energy to heat and cool relatively small buildings.
Curious to see buildings sorted by their emissions intensity instead? Check out the homepage!
Note: Data includes large Chicago buildings with data from 2022, unless explicitly stated otherwise.
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.” This dataset is also then filtered to only buildings with
reported emissions > 1,000 metric tons CO2 equivalent.
The latest year of data is from 2022, 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.
