Financial Services IFRS Industry Guidance
Financed emissions, credit exposure, insurance risk, and capital-market disclosure topics for IFRS reporters.
The largest carbon emitter in the financial sector is not a bank. It is not an insurance company. It is a loan portfolio — a collection of promises to repay that, if the borrowers are in carbon-intensive industries, represents a climate risk no balance sheet has ever fully captured. A commercial bank in Frankfurt lent €2 billion to a coal-fired power plant in 2015. The plant's assets are now stranded. The loan is non-performing. The bank's climate risk disclosure, filed under an older framework, mentioned "transition risk" in a single paragraph. It did not quantify the exposure.
IFRS S2's industry-based guidance for financial services changes that. Banks must disclose financed emissions — the greenhouse gas emissions associated with their lending and investment portfolios. Insurance companies must disclose their exposure to climate-related physical risks — properties in flood zones, coastal infrastructure, wildfire-prone regions. Asset managers must disclose how they integrate climate risk into investment decisions. The guidance covers commercial banks, insurance, asset management, investment banking, mortgage finance, and consumer finance.
Under IFRS S2 §27–36, financial institutions must report their financed emissions using the Partnership for Carbon Accounting Financials (PCAF) methodology. They must disclose their exposure to carbon-intensive sectors and explain how climate risk affects their credit risk models. The €2 billion coal loan — once buried in a single paragraph about "transition risk" — becomes a quantifiable, comparable, auditable disclosure. The loan portfolio is no longer invisible. It is measured.
Financial services climate risk is not on the balance sheet — it is in the loan portfolio, the investment book, and the insurance underwriting that IFRS S2 requires to be quantified.
In Plain Language
Financial institutions do not emit carbon from smokestacks — they emit it through their loan portfolios, investment books, and insurance underwriting. IFRS S2 §27–36 requires banks, insurers, and asset managers to quantify and disclose financed emissions using the PCAF methodology. Under IFRS S2 §8–24, institutions must describe how climate-related transition risks — including carbon-intensive sector exposure, stranded asset risk in lending portfolios, and physical climate impacts on insured properties — affect their business model and credit risk frameworks. The ISSB codified SASB Standards for commercial banks, insurance, asset management, investment banking, mortgage finance, and consumer finance into IFRS S2's industry-based guidance. Each sub-industry has its own disclosure topics: financed emissions measurement and methodology, credit exposure analysis across carbon-intensive sectors, climate risk integration into insurance underwriting and pricing, and ESG integration into asset management portfolio construction and stewardship. ISAE 3000 and ISSA 5000 provide the assurance framework — financed emissions data must be traceable from the loan-level PCAF calculation through portfolio aggregation to the final disclosed figure, with source evidence retained at each step. These four requirements map the specific metrics that translate financial climate exposure into investor-grade disclosure, supported by source evidence that an assurance provider can verify.
- Financial services climate risk is not on the balance sheet — it is in the loan portfolio, the investment book, and the insurance underwriting that IFRS S2 requires to be quantified.
- Financed emissions use the PCAF methodology to allocate greenhouse gas emissions across lending and investment portfolios, making invisible climate risk visible.
- The practical test is whether a bank can show an investor exactly how much climate risk sits in its loan book — not as a narrative, but as a number.
Technical Requirements
- Financed emissions (PCAF methodology) — IFRS S2 §27–36: Banks and asset managers must disclose greenhouse gas emissions associated with their lending and investment portfolios, calculated using the Partnership for Carbon Accounting Financials methodology.
- Credit exposure to carbon-intensive sectors — IFRS S2 §8–24: Financial institutions must disclose the proportion of their loan book and investment portfolio exposed to carbon-intensive industries and describe how climate risk affects their credit risk models.
- Insurance underwriting climate risk — IFRS S2 §8–24: Insurers must quantify their exposure to climate-related physical risks — properties in flood zones, coastal infrastructure, wildfire-prone regions — and disclose how climate change affects their underwriting assumptions.
- Asset management ESG integration — IFRS S1 §21–24: Asset managers must disclose how they integrate climate-related risks and opportunities into investment decision-making and portfolio construction, including stewardship and engagement policies.
