Members of the United Nations-supported Net-Zero Banking Alliance voted to immediately cease operations and move to a guidance-based approach, the group confirmed. 

Banks will help determine how the work continues over the next six to twelve months, with further plans expected after that review.

The decision makes the alliance the second U.N.-aligned climate coalition to halt activities in 2025, after the Net Zero Asset Managers initiative suspended operations earlier this year. 

That followed the departure of the world’s largest asset manager in January, accelerating questions about the durability of voluntary net-zero clubs.

The vote was telegraphed in late August when the alliance proposed abandoning its membership model after an industry exodus that began in the U.S. and spread to Canada and Europe. 

Six major U.S. banks left between late December and early January, ahead of the presidential inauguration. 

Canada’s six largest banks followed before the end of January, and the departures crossed the Atlantic in July and early August as leading U.K. lenders exited, with a Swiss giant withdrawing before the vote was announced.

In April, after the North American departures, the alliance issued a third version of its climate target-setting guidance that no longer required banks to strictly align with a 1.5 degrees Celsius pathway. 

The group said its focus is to establish that guidance as a framework for the industry, allowing individual banks worldwide to use the resources to develop and deliver their own transition plans.

The alliance’s website now redirects to a consolidated resource page that includes a fourth version of its target-setting guidance.

The latest iteration removes references to the alliance and its signatories, positioning the materials as sector-wide resources for banks rather than membership obligations.

Investor advocates called the vote a setback. A co-director at a responsible investment nonprofit said it was disappointing to see the largest banks step away from accountability, arguing that public support for climate action remains high and that many investors recognize the economic risks of a worsening climate.

Supporters of the shift contend that public guidance without membership could broaden adoption while reducing political friction. 

Critics counter that dropping a formal membership model erodes transparency and comparability, complicating efforts to judge progress and to differentiate leaders from laggards.

What happens next will hinge on whether the industry-led guidance gains traction inside banks’ credit, capital and client-facing policies. 

The transition from a club to an open framework may keep technical tools alive, but it also transfers responsibility back to individual institutions and their regulators.
