Financed emissions disclosure is no longer a purely voluntary exercise. A converging set of global and regional regulations now either explicitly require or strongly incentivise financial institutions to measure and disclose the GHG emissions associated with their lending and investment portfolios. This lesson maps the four most important regulatory frameworks and explains how PCAF data satisfies each.
TCFD: The Foundational Voluntary Framework
The Task Force on Climate-related Financial Disclosures (TCFD) was established by the Financial Stability Board in 2015. Its 2017 recommendations (and 2021 update) established the architecture now used by regulators worldwide. For financial institutions, the TCFD framework has four pillars:
- Governance: Board and management oversight of climate-related risks and opportunities
- Strategy: How climate scenarios affect the institution's strategy and business model
- Risk Management: Processes for identifying, assessing, and managing climate risks
- Metrics and Targets: The quantitative data used to monitor performance, including financed emissions
Under the Metrics and Targets pillar, TCFD explicitly recommends that banks, asset managers, and insurance companies disclose:
- Weighted average carbon intensity (WACI) of their portfolios
- Total carbon emissions associated with their portfolio holdings
- Exposure to carbon-related assets as a percentage of total portfolio
PCAF's financed emissions methodology directly produces the WACI and total carbon emissions metrics required by TCFD. Financial institutions with PCAF-aligned disclosures can satisfy the quantitative requirements of the TCFD Metrics pillar using the same dataset.
The ISSB has formally absorbed the TCFD framework. ISSB standards supersede TCFD recommendations in jurisdictions that adopt them, but the substantive requirements for financial institutions (including financed emissions disclosure) are substantially preserved under IFRS S2.
IFRS S2: The Global Mandatory Baseline
IFRS S2 Climate-related Disclosures, published by the International Sustainability Standards Board (ISSB) in June 2023, establishes the global baseline standard for climate reporting. It is designed to be adopted by national regulators, creating mandatory requirements where TCFD was voluntary.
For financial institutions, IFRS S2's most significant requirement is the disclosure of Scope 3 Category 15 (investments) emissions when material. IFRS S2 specifically requires:
- Disclosure of GHG emissions associated with the institution's loans and investments (financed emissions)
- The methodology used (financial institutions are expected to reference PCAF or a similarly robust standard)
- Coverage of relevant asset classes
- Quantitative metrics (absolute financed emissions and intensity)
IFRS S2 has been adopted by jurisdictions covering a large share of global capital markets, including Canada, Australia, Singapore, Japan, Nigeria, and the UK (with full adoption expected by 2026). The EU is implementing its own equivalent through the CSRD/ESRS framework.
PCAF as a compliance tool for IFRS S2
A Singapore-listed bank is now subject to mandatory IFRS S2 reporting as of 2025. When preparing its IFRS S2 disclosure note on Scope 3 Category 15 emissions, the bank references its PCAF-aligned financed emissions report:
"The Group has calculated its financed emissions in accordance with the PCAF Global GHG Accounting and Reporting Standard Part A (Third Edition, December 2025). The methodology, coverage, absolute emissions, data quality scores, and emission intensity metrics are presented in the Annual Sustainability Report, Annex C: Financed Emissions."
This cross-reference satisfies the IFRS S2 requirement without requiring separate calculation. One PCAF dataset serves both the regulatory and sustainability reporting obligation.
EU SFDR: Principal Adverse Impact Indicators
The EU Sustainable Finance Disclosure Regulation (SFDR) (Regulation 2019/2088) applies to financial market participants and financial advisers in the EU. It requires disclosure of Principal Adverse Impacts (PAIs) at both the entity level and the product level.
The mandatory PAI indicators most directly related to financed emissions include:
- PAI 1: GHG emissions (Scope 1, 2, and 3 of investee companies)
- PAI 2: Carbon footprint (total Scope 1+2 financed emissions / total portfolio value)
- PAI 3: GHG intensity of investee companies (Scope 1+2 / revenue)
- PAI 4: Exposure to companies in the fossil fuel sector (% of investments)
- PAI 7: Activities negatively affecting biodiversity-sensitive areas
PCAF's financed emissions methodology directly produces the data required for PAI 1, 2, and 3. Financial institutions with a PCAF-aligned reporting system can generate their SFDR PAI metrics using the same underlying emissions dataset.
SFDR requires disclosure at two levels:
Entity-level (Article 4): All financial market participants with more than 500 employees must publish a PAI Statement on their website. This covers the entity's entire investment portfolio.
Product-level (Articles 8 and 9): Products that promote environmental or social characteristics (Article 8) or have sustainable investment as their objective (Article 9) must disclose how they address PAIs in their pre-contractual (product prospectus) and periodic (annual) reports.
The PCAF financed emissions framework is most directly applicable to the entity-level PAI Statement, where the institution reports on its entire portfolio. Product-level PAI calculation for specific funds may require additional analytical layers, but draws on the same underlying emissions data.
EU Pillar 3 ESG Disclosures
Under the EU Capital Requirements Regulation (CRR/CRD), the European Banking Authority (EBA) introduced mandatory Pillar 3 ESG risk disclosures for large EU banks in 2022. These include quantitative templates specifically covering climate-related financial risks, including:
- Table 1: Qualitative information on environmental risks
- Annex I (Template 5): Financed emissions by sector
- Annex I (Template 7): Taxonomy-aligned portfolio exposures
Template 5 requires banks to disclose financed emissions by NACE sector code, broken down by Scope 1, Scope 2, and Scope 3 of the investee/borrower. PCAF's asset-class and sector-level disaggregation requirements directly enable the data needed for EBA Pillar 3 Template 5.
Connecting the Frameworks
| Framework | Scope | Status | Key FE Requirement | PCAF Produces It? |
|---|---|---|---|---|
| TCFD | Global | Absorbed by ISSB | WACI, total portfolio carbon | Yes |
| IFRS S2 | Global (by adoption) | Mandatory where adopted | Scope 3 Cat 15 disclosure | Yes |
| EU SFDR | EU | Mandatory | PAI 1, 2, 3 (GHG indicators) | Yes |
| Basel Pillar 3 | EU banks | Mandatory (EBA) | Template 5 financed emissions by sector | Yes |
| PCAF | Global (voluntary) | Voluntary (over 540 signatories) | Full financed emissions inventory | Primary standard |
The key insight is that PCAF is not one framework among many alternatives. It is the underlying measurement methodology that produces the data needed to satisfy multiple regulatory and voluntary disclosure frameworks simultaneously. Financial institutions that invest in a robust PCAF implementation are not building for PCAF alone. They are building the data infrastructure that enables compliance with IFRS S2, SFDR PAI, EBA Pillar 3, and future requirements as they emerge, all from a single, coherent financed emissions dataset.
Think of PCAF as the accounting system behind a company's financial statements. The statutory annual report, the management accounts, the tax filing, and the investor pack all draw from the same underlying accounting system, even though they present the information differently and comply with different rules. PCAF is that underlying accounting system for climate data. Once it is in place, the reporting obligations become largely a matter of formatting and presentation.
Key Takeaways
- 1PCAF data directly satisfies the quantitative requirements of TCFD Metrics and Targets (WACI, total portfolio carbon), now absorbed into ISSB standards
- 2IFRS S2 effectively mandates Scope 3 Category 15 disclosure for financial institutions - referencing a PCAF-aligned report satisfies this requirement
- 3EU SFDR PAI indicators 1, 2, and 3 (GHG emissions, carbon footprint, GHG intensity) are all producible from a single PCAF dataset
- 4EBA Pillar 3 Template 5 requires financed emissions by NACE sector code - PCAF's sector-level disaggregation directly enables this
- 5PCAF is the underlying measurement methodology that serves multiple regulatory frameworks simultaneously - one robust implementation avoids separate calculations for each obligation
