Swiss Re, the Zurich-based global reinsurer, has decided to discontinue its pursuit of Science Based Targets initiative (SBTi) validation for its climate targets. Despite this move, the company affirmed that its overarching sustainability strategy remains intact. It reiterated its long-term ambition to achieve net zero greenhouse gas emissions across its operations by 2050.

The decision marks a shift in Swiss Re’s external engagement on climate accountability frameworks, but not a retreat from its internal goals. The company had originally committed to the SBTi in 2019 as part of its broader effort to align with international best practices on climate action.

US Political Pressure Sparks Scrutiny of ESG Climate Commitments

Swiss Re’s decision comes at a time when SBTi itself is facing political backlash, particularly from the United States. A recent campaign spearheaded by anti-ESG lawmakers has called into question the legality of net zero coalitions. Specifically, 23 US state attorneys general issued a warning letter in August, suggesting that participation in the SBTi’s new financial sector framework could potentially violate federal and state antitrust and consumer protection laws.

This growing political pressure follows the July release of the SBTi’s Financial Institutions Net-Zero (FINZ) Standard. The new framework introduces detailed criteria for financial institutions to align their investment, lending, insurance, and capital markets portfolios with net zero objectives.

New Rules Demand Transparency on Fossil Fuel Financing

The FINZ Standard introduced a range of stringent requirements, including mandatory disclosure of fossil fuel-related financing policies. It urged financial firms to immediately halt financing for new fossil fuel expansion projects and to stop providing general-purpose funds to companies still engaged in coal and oil and gas development. These policies aim to drive a systemic shift away from fossil fuels across global capital flows.

While intended to accelerate climate action, these requirements have sparked controversy. Critics argue that they could limit the autonomy of financial institutions and may lead to regulatory risks, particularly in jurisdictions with competing political priorities.

Swiss Re Opts for Independent Route to Net Zero

Although Swiss Re has chosen to exit the SBTi validation pathway, it emphasised that its internal sustainability roadmap remains unchanged. The firm said it will continue implementing its Climate Transition Plan, which outlines interim goals and milestones for decarbonising its underwriting and insurance portfolios.

Among these targets is a commitment that by 2025, at least 50% of the company’s gross written premiums in the oil and gas sector will come from companies aligned with net zero. This share is expected to increase to 100% by 2030. The plan also includes guidelines for reducing exposure to fossil fuel risks while supporting clients in their own energy transitions.

Reaffirming Long-Term Strategy Amid a Shifting ESG Landscape

In its latest statement, Swiss Re made no direct reference to the political or regulatory pressures that may have influenced its decision. However, it maintained that stepping away from formal SBTi validation does not reflect a retreat from sustainability commitments. A spokesperson told ESG Today that the firm’s strategy is continuing “as planned.”

The company added: “With its Climate Transition Plan, Swiss Re has set interim milestones on the path to net zero. Our focus now is on further implementing our sustainability strategy and supporting our clients in their net zero journey through this highly dynamic environment.”

Broader Implications for the Insurance and Finance Sector

Swiss Re’s move highlights the growing tension within the global finance sector over how to navigate net zero commitments amid rising political scrutiny. The insurance industry, in particular, faces unique challenges in aligning underwriting activities with decarbonisation goals while avoiding legal or reputational risks.

While some institutions may continue to pursue third-party validations like SBTi, others, like Swiss Re, may seek more flexible internal pathways. The outcome could redefine how climate commitments are evaluated and communicated, especially in politically polarised environments.

As regulatory landscapes continue to evolve, Swiss Re’s approach may signal a broader trend: prioritising customised sustainability strategies over prescriptive third-party frameworks. What remains to be seen is whether this approach will maintain credibility with investors, regulators, and the broader public in an increasingly transparent ESG arena.
