Financed emissions account for around 95% of banks’ CO₂ footprint. They arise from loans and investments and fall under the Scope 3 category of the Greenhouse Gas Protocol. This article shows how banks and family offices can measure, manage, and reduce these emissions—a challenge that is rapidly moving to the top of the financial sector’s agenda as regulatory and stakeholder pressures mount. Here are the key points:
- Definition: Financed emissions are indirect emissions caused by loan and investment portfolios, and are often far greater than banks’ direct operational emissions. According to the PCAF 2022 Annual Report, these emissions can be up to 700 times higher than a bank’s own footprint.
- Regulations: EU directives such as CSRD, EU Taxonomy, and SFDR require expanded reporting and sustainable strategies, pushing institutions toward greater transparency and action.
- Measurement: The PCAF standard provides methods for accurate calculation, e.g., for equities, loans, real estate, and vehicles. This standardized approach is now widely adopted by leading banks and asset managers globally.
- Data sources: Verified emissions reports (Level 1) to industry averages (Level 4) are crucial, with data quality directly impacting the credibility of disclosures and the effectiveness of reduction strategies.
- Steps to reduction: Portfolio analysis, emissions measurement, and integration into ESG reports are essential for meeting both regulatory and market expectations.
Quick comparison of key regulations:
| Regulation | Main aspects | Impacts |
|---|---|---|
| CSRD | Reporting obligations for non-financial information | 15,000 companies affected in Germany |
| EU Taxonomy | Defines sustainable economic activities | Introduction of the Green Asset Ratio (GAR) |
| SFDR | Transparency requirements | Disclosure of sustainability risks |
This guide offers concrete approaches to managing financed emissions and meeting regulatory requirements. Start with a portfolio analysis and leverage specialized tools for data management and ESG reporting. As the UNEP Finance Initiative notes, tackling financed emissions is now seen as the “next frontier” for banks on climate.
PCAF Standard Measurement Guide
PCAF Basics
The Partnership for Carbon Accounting Financials (PCAF) Standard is the leading method for measuring and reporting financed emissions. More than 550 financial institutions worldwide use this standard, which provides a clear framework for assessing climate risks in the financial sector. The PCAF approach is endorsed by the UN-convened Net-Zero Asset Owner Alliance and is increasingly referenced by regulators and investors alike.
The standard covers seven asset classes:
| Asset Class | Valuation Approach | Special Features |
|---|---|---|
| Listed equities & bonds | Enterprise value-based | Emissions allocated proportionally by ownership share |
| Corporate loans | Loan volume-based | Considers loan maturity |
| Project finance | Project-specific | Total project emissions are allocated |
| Commercial real estate | Area-based | Incl. energy consumption data |
| Mortgages | Property-based | Assessment of building energy efficiency |
| Vehicle finance | Vehicle-specific | CO₂ emissions per vehicle are considered |
| Sovereign bonds | Country-based | National emissions data used |
Calculation Methods
The PCAF standard uses a bottom-up approach to enable detailed assessment at the client level. This granular method helps financial institutions pinpoint high-emission assets and prioritize decarbonization efforts.
Basic formula for calculation:
"Financed emissions = Attribution factor × Emissions of the company/project"
The attribution factors vary by asset class:
- Listed equities: Investment share of enterprise value
- Loans: Ratio of loan amount to total company debt
- Project finance: Emissions calculated according to financing share
Reliable emissions data are essential for accurate calculations. As highlighted by the CDP, access to high-quality, verified data is a growing expectation from both regulators and investors.
Obtaining Emissions Data
The quality of emissions data is rated using a 5-level system, with Level 1 being the highest and Level 5 the lowest quality. According to Bain & Company, banks that invest in higher-quality data not only improve compliance but also gain a competitive edge in sustainable finance.
| Data Source | Quality Level | Application |
|---|---|---|
| Verified emissions reports | 1 | Directly measured and audited data |
| CDP database | 2 | Standardized climate reports |
| Sustainability reports | 2–3 | Company-specific information |
| Industry averages | 4 | Estimates based on sector data |
| PCAF data portal | 3–4 | Standardized estimates |
For German retail banks and family offices, the PCAF methodology is particularly relevant as it is compatible with the EU Taxonomy and CSRD requirements. This data forms a solid foundation for ESG reports and further analysis, and is increasingly expected by stakeholders across Europe and beyond.
3-Step Approach to Emissions Management
1. Portfolio Analysis
The first step in capturing financed emissions is a thorough portfolio analysis. Studies show that emissions within a portfolio often far exceed a company’s direct emissions. For example, McKinsey reports that for many European banks, financed emissions can be more than 100 times greater than their operational emissions.
A structured approach to portfolio analysis could look like this:
| Analysis Step | Methodology | Result |
|---|---|---|
| Sectoral assessment | Use of industry averages and proxy data | Identification of high-emission sectors |
| Client-specific analysis | Evaluation of individual emissions data and CDP reports | Determination of detailed emissions profiles |
| Risk classification | Application of PCAF quality scale | Prioritization of measures |
Based on this analysis, precise measurement of emissions can take place in the next step.
2. Emissions Measurement
Emissions are measured according to the PCAF methodology, which ensures a structured and consistent approach. Certain key figures play a central role in accurate measurement:
Key metrics:
- CO₂ equivalents per euro invested
- Absolute emissions, broken down by asset class
- Emissions intensity compared to sector-specific benchmarks
The quality of the underlying data is crucial. A study from March 2023 shows that 373 financial institutions worldwide are already applying the PCAF methodology, reflecting its growing acceptance and the urgency of climate disclosure (PCAF 2022 Annual Report).
3. Integration into the ESG Report
After accurate measurement, emissions data must be integrated into the ESG report to meet regulatory requirements. With the introduction of CSRD, the number of reporting companies in Germany will rise from 550 to around 15,000, making robust ESG reporting a business-critical process.
"The various reporting regimes should be synchronized so that each data point only needs to be reported once. Every CFO could tell stories about how the same data is reprocessed multiple times. More fundamental regulations with less micromanagement are needed. In addition, European and international regulations must be interpreted and aligned consistently."
An ESG report should cover the following core aspects:
| Report Component | Requirements | Relevant Standards |
|---|---|---|
| Emissions metrics | Absolute and relative CO₂ values | GRI 305, CSRD |
| Risk assessment | Evaluation of climate-related risks in the portfolio | ISSB, Pillar 3 |
| Targets | Science-based reduction targets | Paris Agreement |
| Action plan | Concrete steps for decarbonization | EU Taxonomy |
Integrating this data requires a central platform that consolidates information from various sources and ensures seamless documentation. It is especially important to consider double materiality as required by CSRD. This demands assessment of both the impact on the company and the company’s impact on the environment and society. The concept of double materiality is now seen as a cornerstone of credible sustainability reporting.

FAQs
How can retail banks and family offices analyse and reduce their financed emissions?
Retail banks and family offices can better understand and assess their financed emissions by applying the PCAF methodology (Partnership for Carbon Accounting Financials). This approach provides a clear method for calculating the greenhouse gas emissions resulting from financing activities. The focus is especially on Scope 3 emissions (Category 15), which are caused by the activities of borrowers and investments. A detailed analysis of the portfolio makes it possible to measure and disclose these emissions transparently.
To effectively reduce emissions, it is crucial to develop sustainable financing strategies. This includes targeted investment in low-carbon and environmentally friendly projects as well as integrating ESG objectives into the decision-making process. These approaches not only help achieve climate goals but also strengthen the long-term stability and sustainability of portfolios.
What are the benefits of the PCAF standard for measuring and reporting financed emissions?
The PCAF standard (Partnership for Carbon Accounting Financials) provides financial institutions with a unified method to calculate and disclose the greenhouse gas emissions of their investment and credit portfolios. This facilitates comparison between institutions and strengthens accountability within the sector.
Furthermore, the standard helps banks and family offices to set science-based climate targets aligned with the Paris Agreement. Thanks to specific approaches for different asset classes, the PCAF standard enables precise reporting that meets both regulatory requirements and supports ESG objectives.
What is the importance of the EU Taxonomy and CSRD for the regulation of financed emissions, and how can financial institutions practically implement these requirements?
The EU Taxonomy and the CSRD (Corporate Sustainability Reporting Directive) play a central role in the regulation of financed emissions. The EU Taxonomy defines which economic activities can be classified as sustainable and obliges financial institutions to assess and disclose their investments and loans accordingly. The main objective: to create greater transparency and direct capital towards sustainable projects.
The CSRD expands these requirements by obliging financial institutions to provide detailed reports on their financed emissions. To meet this obligation, companies should rely on standardised methods such as the PCAF standards (Partnership for Carbon Accounting Financials). These standards provide a unified basis for measuring and disclosing emissions. At the same time, they support the achievement of ESG objectives and compliance with regulatory requirements. Accurate data and transparent reporting are indispensable in this context.
