Scope 3 Category 15 — financed emissions — represents the greenhouse gas emissions generated by the activities that financial institutions fund through loans, investments, and underwriting. For most banks, asset managers, insurers, and development finance institutions, Category 15 typically accounts for 95–99% of their total GHG footprint, dwarfing all other Scope 1, 2, and Scope 3 categories combined.
The Partnership for Carbon Accounting Financials (PCAF), the industry standard for financed emissions accounting, estimates that global financial institutions collectively finance approximately $847 trillion in economic activity annually. If this financed activity is measured at the global average emission intensity of economic output, the implied financed emissions footprint of the financial sector exceeds 15 gigatonnes of CO₂ equivalent per year — roughly equivalent to the total annual emissions of China and the US combined.
The GHG Protocol Scope 3 Standard, revised in 2023, now explicitly requires financial institutions to calculate and disclose Category 15 emissions using asset-class-specific methodologies from the PCAF Standard: listed equity and corporate bonds (using outstanding loan/investment proportion × company emissions), business loans (production-based allocation for oil and gas; EEIO models for other sectors), project finance (contractor method or equity-share method), and commercial real estate (building emissions intensity × floor area).
The regulatory landscape is rapidly making Category 15 disclosure mandatory. The SEC Climate Disclosure Rule requires Scope 3 disclosure (including Category 15) for large accelerated filers where material. The EU Sustainable Finance Disclosure Regulation (SFDR) requires financial products to disclose principal adverse impacts including financed emissions. ISSB S2 requires disclosure of financed emissions for financial institutions. The NZBA net-zero banking alliance requires Category 15 targets across all material portfolio sectors by 2050.
The ESG Reporting System's Category 15 Module implements the full PCAF Standard v2.0 methodology for all asset classes, integrating with portfolio management systems (Bloomberg, Aladdin, eFront) to retrieve holding-level data, cross-referencing company-disclosed Scope 1 and 2 emissions from CDP and MSCI datasets, applying EEIO emission intensity models where direct data is unavailable, and generating PCAF-compliant financed emissions inventories with confidence score classifications (A through D) per holding.
