Net Zero Insurance Alliance exodus
Mass departure of major insurers and reinsurers from the Net Zero Insurance Alliance in 2023, under perceived US antitrust pressure.
Between March and June 2023, Munich Re, Zurich, Hannover Re, AXA, Allianz, SCOR and Swiss Re walked out of the Net Zero Insurance Alliance one after another, stripping it of nearly all its major members less than two years after its July 2021 launch. The NZIA pooled commitments to align underwriting portfolios with a net zero pathway, modeled on the investor-side alliances. The trigger is on the record. In the United States, several state attorneys general threatened antitrust action against climate coalitions that bring competitors together around coordinated commitments, and members judged that exposure out of proportion to the reputational upside of staying in. The leavers cited competition law, not any quarrel with the target itself. Hence a fragility specific to voluntary commitments that direct competitors make jointly. Once they can be read as concerted action on market terms, they carry a legal risk distinct from the reputational risk that justified them in the first place. Since 2023, insurers have published more individual climate commitments and coordinated far less in public.
Between March and June 2023, most of the major members of the Net Zero Insurance Alliance left one after another: Munich Re, Zurich, AXA, Allianz, SCOR and Swiss Re, which had founded it in July 2021, and Hannover Re, which joined later. All cited antitrust legal risk rather than any disagreement with the climate objective itself.
