IBM emissions by source 2021

IBM's Scope 2 market-based indirect greenhouse gas emissions totaled 411,211 metric tons of carbon dioxide equivalent (tCO2e) in 2021. The main source of IBM's scope 2 emissions in 2021 was electricity use in managed locations, though emissions from this category have fallen considerably in recent years. Meanwhile, the use of fossil fuels for operations was the largest source of Scope 1 direct emissions in 2021, at 69,634 tCO2e.
