Key Findings

  • Global GHG emissions totaled 49.7 tCO₂e in 2019, and Fortune 500 companies accounted for 13.15 tCO₂e of that amount.

  • Actual reported emissions from Fortune 500 companies equalled 8.04 billion tonnes CO2e in 2018 and 7.56 billion tonnes CO2e in 2019.

  • Fortune 500 aggregate Scope 3 emissions totalled 5.68B tCO₂ in 2019

  • The combined GHG footprint for Fortune 500 companies is estimated to have been 13.34 billion tonnes CO2e in 2018 and 13.15 billion tonnes CO2e in 2019.

  • Corporate emission footprints publicly disclosed to stakeholders often cite lower volumes of emissions than what is disclosed to CDP.

  • A combination of carbon removal and renewable energy deployment are the only solutions currently available that have the potential to match the GHG reduction needed, based on estimated emission rates, however their efficacy is dependent on the ability to scale these two industries at an urgent pace.

  • Stronger governmental regulation and oversight is likely required to ensure both emission reporting and emission reductions accelerate on schedule with science-based targets.
