Climate factor briefing

The European Central Bank (ECB) will introduce a 'climate factor' on 15 June 2026 to adjust the valuation of marketable assets issued by non-financial corporations used as collateral. The factor penalizes assets tied to high-emission activities based on sector-specific stressors, issuer-specific climate scores, and asset maturity. Reclaim Finance argues the measure is a positive step but suffers from transparency gaps and a flawed annual calculation cycle that may misrepresent risks for short-term assets. The briefing recommends making climate factors public, automating calculations, and extending the framework to credit claims and other asset classes to ensure comprehensive integration of climate risks into monetary policy.

• Starting 15 June 2026, the ECB will implement a 'climate factor' to adjust the valuation of marketable assets issued by non-financial corporations and their affiliates when used as collateral in lending operations.
• The climate factor is based on an 'uncertainty score' derived from three components: a sector-specific stressor (based on ECB climate stress tests), an issuer-specific stressor (based on GHG emissions, targets, and disclosure quality), and asset-specific vulnerability (measured by residual maturity).
• The climate factor aims to make assets tied to high-emission activities less appealing for banks to hold and pledge, potentially raising funding costs for high-emitting corporations, though some estimates suggest the impact on bond yields may be as low as 0.1bps.
• The current design calculates the climate factor only once per year, meaning new assets are assigned a median factor for up to 12 months, which may misrepresent risks—particularly for commercial papers and other short-term assets.
• The ECB's current scope for the climate factor is limited, covering less than 5% of assets pledged as collateral in the Eurosystem.
• Reclaim Finance recommends extending the climate factor to credit claims (bank loans), which represented approximately 29% of pledged collateral in the last quarter of 2025, suggesting a simplified version based on sectoral data to overcome data gaps for smaller corporations.
