Financed emissions are the greenhouse gas emissions linked to a financial institution’s lending, investment, and underwriting activities. Classified under Scope 3 Category 15 of the Greenhouse Gas (GHG) Protocol, they represent the indirect emissions generated by the companies, projects and assets being financed. For banks, insurers, and asset managers, financed emissions typically account for the vast majority of their reported carbon footprint, often exceeding 90% of total reported emissions, according to the Global GHG Accounting and Reporting Standard by Partnership for Carbon Accounting Financials (PCAF) and financial-sector climate disclosures.
What Are Financed Emissions and Why They Matter for Banks
Unlike manufacturers or industrial companies, banks and financial institutions generate relatively few operational emissions from their offices, branches, and data centres. Their largest climate impact comes from the activities they finance. This distinction is reflected in Scope 1, 2, and 3 framework, where financed emissions are reported under Scope 3 Category 15.
Definition and Boundary
Financed emissions are the greenhouse gas emissions produced by borrowers, investees, project counterparties, and insured entities that are attributed to a financial institution in proportion to its share of financing. Although the institution does not directly generate these emissions, they are attributed to it because its financing enables those activities to take place. As a result, capital allocation has become an important lever for driving real-economy decarbonisation.
Why Financed Emissions Dominate the Bank Footprint
Financial institutions typically report relatively low Scope 1 and Scope 2 emissions arising from office operations, electricity consumption, and business travel. In contrast, emissions associated with lending and investment portfolios are often several orders of magnitude larger, commonly accounting for more than 90% of an institution’s total reported emissions.
Since they dominate the overall emissions profile, financed emissions have become the single most material climate disclosure category for banks and other financial institutions. Growing investor expectations, evolving regulatory expectations from bodies such as SEBI and the Reserve Bank of India (RBI), and increasing climate-risk assessments have elevated financed emissions from a reporting metric to a strategic board-level consideration.
Financed Emissions as Scope 3 Category 15
The GHG Protocol divides the indirect emissions into fifteen Scope 3 categories, covering emissions that occur across an organisation’s value chain. For financial institutions, Category 15 of Scope 3 is by far the most significant category. It includes emissions associated with corporate loans, project finance, listed and private equity investments, corporate bonds and debt holdings, residential mortgages, motor vehicle loans, commercial real estate financing, and sovereign debt holdings.
Rather than being based on operational control, financed emissions are attributed according to the financial institution’s economic interest or share of financing in each asset. As reporting frameworks continue to evolve, off-balance-sheet activities such as underwriting and capital market facilitation are also receiving greater attention, reflecting the broader climate impact of financial intermediation.
How Financed Emissions Are Measured
Financed emissions are calculated by combining a borrower’s greenhouse gas emissions with an attribution factor that reflects the financial institution’s share of financing.
The Partnership for Carbon Accounting Financials (PCAF) has developed the globally recognised methodology for measuring financed emissions across different asset classes. The standard provides harmonised accounting approaches, a data quality scoring system, and guidance for improving reporting accuracy as borrower-level emissions data becomes more readily available.
PCAF Methodology Basics
The PCAF Standard provides asset-class-specific guidance covering:
- Listed equity and corporate bonds,
- Business loans,
- Project finance,
- Residential mortgages,
- Commercial real estate, and
- Motor vehicle loans.
Each asset class has its own attribution formula and recommended data quality hierarchy, ranging from borrower-reported emissions (highest quality) to industry-average estimates and proxy data where primary information is unavailable. Institutions are expected to improve data quality progressively over successive reporting cycles.
Calculation Components
| Element | Explanation |
| Attribution factor | Financial institution’s proportional share of financing relative to the borrower’s total capital or outstanding debt, depending on the applicable PCAF methodology |
| Financed activity | Loans, equity investments, bonds, project finance, mortgages, motor vehicle loans, sovereign exposure |
| Emissions data | Primarily the borrower’s Scope 1 and Scope 2 emissions, and Scope 3 emissions where required by the applicable asset class methodology |
| Output | Proportional greenhouse gas emissions attributed to the financial institution’s portfolio |
Asset Classes Covered in Financed Emissions
Financial institutions hold a wide range of assets, each requiring a distinct accounting methodology under the PCAF Standard.
| Asset Class | Examples |
| Corporate lending and equity | Listed and private companies across sectors |
| Project finance | Infrastructure, energy generation, mining projects |
| Mortgages | Residential housing portfolios |
| Commercial real estate | Offices, malls, industrial assets |
| Motor vehicle loans | Auto financing, fleet portfolios |
| Sovereign exposure | Government bonds and treasury holdings |
In practice, the largest absolute financed emissions for most diversified banks come from corporate lending to high-emission sectors (steel, cement, power, oil and gas). Project finance can also contribute significantly, particularly where financing supports high-emission infrastructure. Commercial real estate, motor vehicle loans, mortgages, and sovereign debt typically contribute smaller but still material portions of portfolio emissions. Because each asset class follows a different accounting approach, comprehensive financed emissions reporting generally evolves over multiple reporting cycles.
Challenges and How Financial Institutions Reduce Financed Emissions
Reducing financed emissions is significantly more challenging than reducing Scope 1 or Scope 2 emissions because the financier does not directly control the activities that generate them. Instead, they must work with borrowers and investees, support credible transition plans, and align capital allocation with long-term decarbonisation pathways. Accurate emissions data is essential for measuring progress and setting portfolio-level targets.
Measurement Challenges
- Data availability: many borrowers, particularly small and mid-size enterprises, do not yet disclose emissions, forcing reliance on sector averages and estimation techniques.
- Inconsistent disclosures: emissions definitions and boundaries vary across jurisdictions and reporting frameworks, complicating portfolio aggregation.
- Estimation and proxy use: lower data quality reduces the credibility of reported financed emissions and limit comparability across institutions.
- Portfolio complexity: different asset classes require different methodologies, data sources, and attribution approaches, making portfolio-wide reporting resource-intensive.
Strategies for Reducing Financed Emissions
- Portfolio rebalancing: gradually shifting exposure towards lower carbon and transition-aligned sectors while managing exposure to high-emission activities over time.
- Engagement with high-emission borrowers: Working with carbon-intensive clients such as those in the steel, cement, power, and oil and gas sectors to support credible transition plans and emissions reduction initiatives.
- Sustainable finance products: Green loans, sustainability-linked loans, transition finance and other financing that incentivise borrowers to achieve decarbonisation milestones.
- Net zero alignment: aligning lending and investment decisions with science-based pathways to support long-term portfolio decarbonisation.
Conclusion
Financed emissions have fundamentally reshaped climate accountability for the financial sector. Because lending, investment, and underwriting decisions influence real-economy emissions, financed emissions represent the largest component of the carbon footprint for most banks, insurers, and asset managers.
Reducing financed emissions requires financial institutions to engage with borrowers, support credible transition plans, and align capital allocation with long-term decarbonisation pathways For residual emissions that remain after these efforts, high-integrity voluntary carbon credits, such as Cercarbono-certified ELV carbon credits generated through authorised Registered Vehicle Scrapping Facilities (RVSFs), can complement broader climate strategies. However, they should support, and not replace, efforts to reduce financed emissions through portfolio decarbonisation and responsible capital allocation.
FAQs
Are financed emissions part of Scope 3?
Yes. Financed emissions are classified under Scope 3 Category 15 (Investments) of the Greenhouse Gas Protocol. They cover emissions from loans, investments, bonds, project finance, mortgages, and underwriting exposure, attributed to the financier in proportion to its share of financing.
Why are financed emissions so high for banks?
Banks report low Scope 1 and Scope 2 from offices and branches, but their lending and investment portfolios enable activities across the real economy. Borrower and investee emissions often account for more than 90% of a bank’s total, making financed emissions dominant component of its carbon footprint.
Who is responsible for reporting financed emissions?
Financial institutions report their own financed emissions under Scope 3 Category 15. The borrower or investee reports its own Scope 1 and Scope 2 emissions, which the financier uses as inputs alongside the attribution factor. Responsibility is shared but distinct: each entity reports its own perspective.
How are financed emissions calculated?
Financed emissions are calculated by combining a borrower’s greenhouse gas emissions with an attribution factor representing the financial institution’s share of financing. The PCAF Standard provides asset-class-specific methodologies, with the emissions boundary varying by asset class. Data quality is scored from 1 to 5, with primary borrower data receiving the highest score and estimated data the lowest.
Are financed emissions mandatory to report?
Disclosure requirements are becoming more stringent globally. In the European Union, institutions within the scope of the Corporate Sustainability Reporting Directive (CSRD) are required to report climate-related information. In India, climate-risk disclosure expectations for banks are evolving under the Reserve Bank of India (RBI), while voluntary frameworks such as PCAF, CDP, and the TCFD have helped establish financed emissions as an important climate disclosure metric.
What sectors contribute most to financed emissions?
The sectors with the largest absolute emissions also generate the largest financed emissions footprint for their financiers: power and utilities, oil and gas, steel, cement, chemicals, automotive manufacturing, and aviation. Real estate and motor vehicle loan portfolios also contribute materially, particularly for retail-oriented banks.
Can voluntary carbon credits help financial institutions address financed emissions?
High integrity voluntary carbon credits can complement broader climate strategies by helping organisations address residual emissions that remain after portfolio decarbonisation efforts. For instance, Cercarbono-certified ELV Carbon Credits (Carboncers) generated through authorised Registered Vehicle Scrapping Facilities (RVSFs) integrating digital monitoring, reporting, and verification systems, provide a high-integrity voluntary carbon credit that may support broader climate commitments. However, they should complement, not replace, efforts to reduce financed emissions through portfolio engagement and responsible capital allocation.
