Swiss Re sustainability score: 55/100

Swiss Re publishes annual Sustainability Reports with KPMG limited assurance on operational GHG data. Scope 1, 2 (market-based), and selected Scope 3 categories disclosed per GHG Protocol. ~29,000 tonnes CO2e operational in-scope emissions in 2025, consistent with a ~14,900-employee services firm. Score capped at 6 because material financed/insurance emissions are not operationally owned.

Swiss Re discloses insurance-associated emissions (IAE) using PCAF Part C methodology. 2024 IAE ~1.8 million tonnes CO2e (Scope 1–2 only). Financed emissions for corporate bonds and listed equity: 1.4 million tonnes CO2e (2025). Only 21–22% of portfolio has reported company-level data; majority relies on modelled intensities. Treaty reinsurance (bulk of volume) has no IAE estimate. Scope 3 IAE unpublished due to data quality.

Business air travel GHG reduced 63–64% vs. 2018 baseline by 2023/24. Absolute Scope 1 on track for 53%-by-2030 target. However, corporate bond and listed equity financed emissions rose from 1.3 million tonnes CO2e (2024) to 1.4 million tonnes CO2e (2025). Insurance-associated emissions also revised upward. Only intensity—not absolute emissions from dominant sources—is improving.

Swiss Re has achieved 100% renewable electricity across operations since 2020 via mix of solar installations, virtual power purchase agreements (vPPAs), green tariffs, and high-quality energy certificates. Founding member of RE100 (2014). 2024 target met per Sustainability Report. Score capped at 8 due to incomplete disclosure of procurement method breakdown and limited supplier energy transition evidence.

Swiss Re is a TNFD founding member and developed Biodiversity and Ecosystem Services Index to quantify nature dependencies. Swiss Re Foundation co-funded multi-scale biodiversity scenarios with WWF and EY. ESG Risk Framework restricts high-deforestation underwriting. However, no quantified nature footprint disclosed for own operations or underwriting/investment portfolios. No TNFD-aligned disclosure for Swiss Re's own activities found.

Swiss Re tracks paper, water, and waste consumption published via additional environmental data in 2025 reporting. Waste compensated through carbon certificates in CO2NetZero Programme. Copy paper and water included in Scope 3 Category 1 via Carbon Steering Levy. No formal circularity programme with public metrics or supplier sustainability requirements beyond Vendor Emissions Programme.

Swiss Re tracks and publishes water consumption as part of additional environmental data. Water included in CO2NetZero Programme scope (Scope 3 Category 1). As a professional services firm, operational water footprint is low with no industrial discharge or pollution risk. No formal water stewardship programme, watershed engagement, or independent water verification found.

Operational targets: 53% absolute Scope 1 reduction by 2030 (base 2018); 100% renewable electricity maintained; 60% business air travel reduction by 2026–27. All 2024–25 targets met. CO2NetZero removal at 52% in 2025 (target 50%). However, Swiss Re withdrew from SBTi validation September 2025, removing external verification. Corporate bond portfolio temperature alignment stuck at 2.4°C (not 1.5°C pathway). Financed targets rely on intensity, not absolute reduction.

2024 Sustainability Report received KPMG limited assurance; 2025 report subject to consultative shareholder vote. Discloses against TCFD, GRI, SASB insurance, UN Global Compact. Board and Group Executive Committee explicitly responsible. Dedicated sustainability team and publicly available Climate Transition Plan. Score capped at 7: executive compensation linkage to sustainability targets not evidenced, and SBTi withdrawal reduces external accountability.

Swiss Re withdrew from SBTi validation September 2025 following US anti-ESG political pressure—a backward step on external accountability (−1 point). InfluenceMap shows mixed lobbying posture on sustainable finance policy (−1 point). Corporate bond portfolio temperature alignment 2.4°C (unchanged 2024–25) contradicts 1.5°C commitments (−1 point). No credible greenwashing rulings or environmental damage controversies. Continues reinsuring oil/gas producers under ESG policy.
