About PCAF
The Partnership for Carbon Accounting Financials (PCAF) is a global partnership of financial institutions working together to empower their sector to measure and disclose the greenhouse gas (GHG) emissions associated with financial activities, and to support greater transparency and accountability.
PCAF signatories develop the “Global GHG Accounting and Reporting Standard for the Financial Industry” (the PCAF Standard) which is aligned with the requirements of the GHG Protocol related to Scope 3, Category 15. As well as this open-source standard, the PCAF signatories develop and maintain a range of practical resources for signatories to support them in implementing the PCAF Standard.
PCAF was founded in 2015 by 14 Dutch financial institutions and has since expanded within Europe and to North America, Latin America, Africa, and the Asia-Pacific region. As of March 2026, more than 700 global financial institutions have become PCAF Signatories, and by doing so demonstrated their commitment to measuring and disclosing on the GHG emissions related to financial activity in line with the PCAF Standard.
About the PCAF Standard
The “Global GHG Accounting and Reporting Standard for the Financial Industry”, also known as the "PCAF Standard", including its ongoing updates and expansion, is governed by the PCAF Core Team and is shaped by the needs of PCAF Signatories.
Since its first release in 2020, the PCAF Standard has expanded to include the financed emissions for ten asset classes, as well as a (re)insurance associated emissions and facilitated emissions.
