The decision to dissolve the Net-Zero Banking Alliance (NZBA) on 3 October has been viewed as a setback for efforts to mobilise private capital for climate-related investment, including the financing of low-carbon infrastructure, clean technology and energy-efficient equipment.

Formed in 2021 under the UN Environment Programme Finance Initiative, the NZBA brought together more than 140 banks at its peak, aiming to align lending and underwriting portfolios with net-zero emissions targets by 2050.

The group’s closure, confirmed after a formal vote by its remaining members, follows months of departures and growing political pressure in the US, where lawmakers questioned whether coordinated climate commitments breached competition laws.

A spokesperson said the NZBA would “cease operations immediately,” though its Guidance for Climate Target Setting for Banks and related tools would remain publicly available for individual institutions to use.

For equipment financiers and asset-based lenders, the move raises questions about how banks will now frame their commitments to green investment and emissions reduction targets.

The NZBA’s framework had helped to standardise climate-aligned finance principles and provide a common language for assessing portfolio emission, useful for sectors such as construction, manufacturing and transport, where decarbonisation requires significant capital investment.

Industry observers warned that the loss of the alliance could slow progress towards scaling finance for the energy transition. Jeanne Martin, co-director of corporate engagement at ShareAction, described the decision as “bitterly disappointing,” saying that “senior bankers need to use their influence to push up standards for accountability on climate.”

Lucie Pinson, director of Reclaim Finance, said she “won’t mourn” the alliance’s demise, arguing that “it brought little – if anything – to the climate.” She added that the closure “clarifies the need for policymakers and regulators to intervene if the reallocation of capital toward green solutions is to happen at the necessary scale.”

BankTrack said the dissolution “puts an end to a sad spiral of decline” but warned that it “underscores the urgent need for regulation to force banks to align finance with global climate targets.” The organisation added that the NZBA had “shifted the discussion away from the immediate need to halt financing for fossil fuel expansion,” a move it said was “plainly inconsistent with its stated goals.”

The NZBA’s collapse comes as the equipment finance and project finance sectors look for clearer policy signals to support investment in renewable energy, electric transport, and industrial decarbonisation technologies. With the alliance gone, lenders are expected to rely more heavily on internal frameworks or national-level guidelines to determine what qualifies as green finance.

Analysts said the NZBA’s disbandment could reinforce the case for stronger regulation or tax incentives to support sustainable asset financing. For now, the absence of a unified banking platform leaves a gap in the global coordination of climate finance, one that industry participants say could make mobilising private capital for the “green revolution” more difficult in the short term.
