3i published FY2025 Operational Emissions Assurance report with third-party limited assurance covering Scope 1 and 2 using DEFRA 2024 conversion factors. Scope 1+2 are very small (223-person office footprint). A 3.2% emissions increase from FY2023 base in FY2025 prevented a higher score. Granular methodology and independent verification justify 8/10.

3i reports own Scope 3 at 3,800.3 tCO₂e FY2025 (restated from prior methodology change). However, no aggregate absolute financed emissions disclosed for £38.7bn portfolio—the primary environmental risk channel for a PE firm. Portfolio progress tracked only via SBTi coverage % (23.3% of portfolio by invested capital), not tonnes. Material gap for a financial institution.

Own Scope 1+2 increased 3.2% from FY2023 to FY2025; no absolute financed emissions trajectory available. Portfolio progress tracked via SBTi coverage target (23.3% current, 31% by FY2028). Absence of declining operational trend and lack of absolute financed emissions trajectory cap this score at 3/10.

3i sourced 100% renewable electricity for London, Paris, Frankfurt offices in FY2025; new New York office pending state grid initiatives. Total renewable electricity consumption ~85% FY2025. London office relocated to renewable-only premises with no gas reliance. Clear landlord engagement strategy for remaining 15% justifies 6/10.

3i conducted high-level nature impact assessment of portfolio using open-source tools in FY2025, identifying hotspots for future focus. This is preliminary awareness work, not quantified assessment or formal TNFD-aligned disclosure. No deforestation commitment or verified nature policy found. Portfolio includes retail and infrastructure assets with material supply chain footprints.

3i is office-based with ~223 employees and minimal material footprint. No formal circular economy targets, supplier materials requirements, or waste reporting found for 3i's own operations. Portfolio companies (Action, BoConcept) have sustainability programmes including circularity, but 3i Group itself has not published waste or resource metrics beyond implicit GHG inclusion.

3i is an office-based investment manager with negligible direct water consumption—no industrial, manufacturing, or water-intensive operations. No formal water consumption data, water stewardship programme, or reduction targets found in any public sustainability document. Absence of water policy unsurprising given inherently minimal footprint. Score 3/10 reflects minimal impact and zero formal monitoring.

3i holds SBTi-validated near-term targets (March 2024) covering Scope 1, 2, and financed emissions. Portfolio coverage target: 31% by FY2028, 100% by FY2040 with SBTi-validated targets. Separate 68% per-MWh GHG intensity reduction target by FY2030. No net-zero validation or offset reliance. Reduction-first approach justifies 7/10; coverage approach rather than absolute financed emissions reduction prevents higher score.

3i publishes annual sustainability reports, TCFD disclosures, SASB reports, GRI content index, and Operational Emissions Assurance report with third-party limited assurance. Board oversight, dedicated Sustainability Senior Manager, UN PRI signatory since 2011. Executive compensation linkage to sustainability targets not confirmed. Governance and disclosure structure substantive for a 223-person PE firm; 7/10.

No regulatory rulings, upheld complaints, greenwashing findings, or climate-related lawsuits found. No anti-climate lobbying or membership in trade associations opposing climate policy identified. BankTrack, RAN, InfluenceMap, and DeSmog found no fossil-fuel exposure criticism. Portfolio shows no material fossil-fuel concentration; infrastructure includes renewables and biogas. No structural enablement of fossil sector; 8/10.
