US public companies are increasing disclosure of their scope 3 emissions, the indirect emissions coming from the upstream and downstream parts of their supply chain. In 2023, 77% of S&P 500 companies disclosed scope 3 emissions, as did 43% of Russell 3000 and 38% of S&P MidCap 400.
With regulatory disclosure regimes in the European Union and California targeting even medium-sized companies, more firms should prepare for disclosing their scope 3 emissions. They should also prepare for assurance in their reporting: the EU Corporate Sustainability Reporting Directive (CSRD) requires third-party assurance in relation to companies’ CSRD disclosures, including on scope 3, and the California Climate Corporate Data Accountability Act requires companies to obtain limited third-party assurance for their scope 3 emissions reporting by 2030.
