Our 2022 carbon footprint reduction surpassed our targets. We calculated the carbon footprint of 29 large offices and found that 19 had reduced greenhouse-gas emissions since 2018, our baseline year. Absolute emissions from electricity use, heating fuel, waste, commuting and business travel totaled 2,733 metric tons of CO2e, lower than in 2018.
The shift to remote work caused by COVID-19 curtailed commuting and business travel, leading to a 61% decrease in absolute emissions from 2018 to 2020. As the pandemic eased, commuting and air travel rebounded. Combined with the firm’s growth, this led to a 47% increase from 2020 to 2022. Our total reduction for 2018 to 2022, however, was 44%. We attribute that overall decrease to efforts to reduce air travel, moves to more energy-efficient office spaces, and less commuting. When purchased offsets and RECs are accounted for, we have achieved a 58% reduction in emissions.
