Financed emissions are the greenhouse gas (GHG) emissions that financial institutions indirectly cause through their lending and investment activities. When a bank provides a loan to a coal-fired power plant or an asset manager buys shares in an oil company, the emissions produced by those businesses are partially attributable to the financial institution that provided the capital.
In formal terms, financed emissions fall under Scope 3, Category 15 (Investments) of the GHG Protocol's Corporate Value Chain Standard. They represent the single largest source of emissions for most financial institutions, often accounting for more than 700 times their direct operational emissions (Scope 1 and 2 combined).
Financed emissions are not the bank's own smokestacks or electricity bills. They are the real-world emissions generated by the companies, projects, and assets that the bank chooses to fund. By measuring these emissions, financial institutions gain visibility into the climate impact of their most consequential decisions: where they allocate capital.
The "Follow the Money" Principle
The foundational logic behind financed emissions accounting is straightforward: follow the money. Every dollar, euro, or yen that flows from a financial institution to a borrower or investee creates a financial relationship. The PCAF Standard translates that financial relationship into an emissions relationship using an attribution factor.
The attribution factor determines what share of a borrower's or investee's total emissions can be associated with a specific financial institution:
Attribution Factor - General Formula
Attribution Factor
The financial institution's proportional share of a borrower's or investee's emissions, expressed as a percentage
Outstanding Amount
The capital deployed by the financial institution to the borrower or investee
Total Company Value
The full financing structure of the borrower or investee (equity plus debt, EVIC, or other denominator depending on asset class)
The outstanding amount is how much capital the financial institution has deployed. The total company value captures the full financing structure of the borrower or investee. By dividing the former by the latter, the financial institution calculates its proportional share of the underlying emissions.
Think of it like co-owning a car. If three people collectively buy a car worth $30,000 and you contributed $10,000, you are responsible for one-third of the car's fuel emissions, even though you did not personally drive it every day. The same principle applies to financed emissions: your share of the funding determines your share of the emissions.
Why Financed Emissions Matter
Financial institutions occupy a unique position in the global economy. They do not mine coal, manufacture steel, or clear forests, but they enable those activities by providing the capital that makes them possible. This role as a capital allocator creates both responsibility and opportunity.
Responsibility: If a bank's loan portfolio is dominated by high-carbon industries, the bank is effectively fueling those emissions. Regulators, investors, and civil society increasingly expect financial institutions to acknowledge and manage this indirect climate impact.
Opportunity: By understanding the emissions profile of their portfolios, financial institutions can redirect capital toward lower-carbon activities, engage borrowers on decarbonisation, and develop innovative green financial products.
Scale of financed emissions in practice
A typical large commercial bank might report Scope 1 emissions of around 50,000 tonnes of CO2 equivalent (tCO2e) from its offices and vehicles, and Scope 2 emissions of around 100,000 tCO2e from purchased electricity. Its financed emissions, however, could exceed 100 million tCO2e, making Scope 3 Category 15 the dominant category by a factor of several hundred.
This disparity underscores why operational efficiency measures alone are insufficient. A bank could achieve net-zero in its own operations while still financing vast quantities of fossil fuel extraction. Financed emissions accounting closes that accountability gap.
The PCAF Standard: A Global Framework
The Partnership for Carbon Accounting Financials (PCAF) was created in 2015 by 14 Dutch financial institutions to address the absence of a standardised methodology for measuring financed emissions. PCAF went global in September 2019, and by 2025, over 540 financial institutions across six continents had committed to the standard.
The PCAF Global GHG Accounting and Reporting Standard is organised into three parts:
| Part | Title | Focus |
|---|---|---|
| Part A | Financed Emissions | On-balance-sheet loans and investments across 10 asset classes |
| Part B | Facilitated Emissions | Off-balance-sheet capital market activities (underwriting, syndication) |
| Part C | Insurance-Associated Emissions | Emissions associated with re/insurance underwriting portfolios |
The Third Edition of Part A (December 2025) covers 10 distinct asset classes, each with its own attribution methodology, data quality scoring system, and worked examples. This course will explore each of these in depth.
What This Course Covers
This course provides a complete guide to financed emissions for sustainability professionals, risk managers, portfolio analysts, and compliance officers working in or with the financial sector. By the end, you will understand:
- How financed emissions are defined and why they are classified under Scope 3, Category 15
- The PCAF methodology for attributing emissions to financial institutions
- All 10 asset class methodologies, from listed equity to sovereign debt
- Facilitated and insurance-associated emissions, which extend the framework beyond lending and investing
- Data quality challenges and practical strategies for improving emissions estimates
- Disclosure requirements, including the PCAF checklist, SBTi alignment, and regulatory expectations
The PCAF Standard is not a voluntary label or aspiration. It is a detailed, technically rigorous accounting framework that is increasingly referenced by regulators (including under IFRS S2, EU SFDR, and Basel Pillar 3 ESG disclosures). Understanding financed emissions is now a core competency for anyone working in sustainable finance.
