Key Impact Points:
- New indicator reveals 30% of ECB’s corporate bond holdings are in sectors highly exposed to nature loss
- Corporate bond tilting accounted for 25% of emission reductions in ECB monetary portfolios since 2021
- ECB sets 7% annual emission intensity reduction target for APP and PEPP corporate bond holdings
ECB Introduces Nature Exposure Metric in Climate Reporting
The European Central Bank (ECB) has released its third climate-related financial disclosure, introducing a new indicator that evaluates how ECB and Eurosystem corporate portfolios depend on or impact nature. This marks a significant step in aligning climate and biodiversity risks within financial oversight.
“Approximately 30% of the Eurosystem’s monetary policy corporate bond holdings are concentrated in the three most exposed sectors, which are utilities, food and real estate,” the ECB reported. The highest nature exposure in the ECB’s staff pension fund appeared in equity ETFs, where 40% of investments are tied to nature-dependent sectors.
Corporate Bond Tilting Cuts Emissions
Emissions from the ECB’s monetary policy portfolios and foreign reserves continued to decline both in absolute and relative terms. According to the report, the corporate bond class remains the most climate-risk-exposed. The ECB’s tilting approach — favoring issuers with better climate performance — played a major role:
“Tilting still accounted for around one-quarter of total emission reductions between 2021 and the end of 2024, when reinvestments were discontinued.”
Climate Targets and Green Bond Holdings Advance
In 2023, the ECB set interim annual emission intensity reduction targets of 7% for corporate bonds under the APP and PEPP to align with the Paris Agreement and EU climate neutrality goals. These targets remain in place and subject to review if deviations occur.
In its own funds portfolio, the ECB increased its green bond share to 28%, with a target of 32% for 2025. Over €6.4 billion has been directed toward green transition financing. It also began investing in ETFs tracking EU Paris-aligned benchmarks.
Corporate investments in the ECB’s staff pension fund saw a 20% drop in carbon footprint in 2024, maintaining alignment with climate objectives.
Data Challenges Remain
The ECB acknowledged persistent limitations in emissions data — especially related to value chain emissions and certain asset classes like covered bonds.
“Inconsistent reporting… makes it difficult to compare these emissions across issuers or over time,” the ECB noted, emphasizing the need for harmonized reporting frameworks to improve investment decisions and risk oversight.
