Frequently asked questions

Which US building emits the most carbon?

Among buildings in city benchmarking disclosures, Coresite Sv8 in California reported the most: 27,420,510 tCO₂e in its latest disclosure year.

Where do these emissions figures come from?

Each figure is the building's own reported total greenhouse-gas emissions (metric tons CO₂e) from its jurisdiction's mandatory energy-benchmarking disclosure — NYC LL84, Boston BERDO, DC BEPS, California AB 802 and every other US program with public data. Only the latest disclosure year per building is ranked.
