Swiss banking giant UBS will withdraw from the Net‑Zero Banking Alliance (NZBA) after an annual review of its sustainability and climate‑related memberships, joining a string of major lenders that have recently left the UN‑convened initiative. The move, announced as part of the bank’s routine reassessment of external partnerships, follows high‑profile exits by Barclays and HSBC and comes amid a broader reshaping of how large financial institutions approach collective climate commitments. According to Reuters, UBS framed the decision as a reflection of its own evolved capabilities rather than a repudiation of net‑zero aims.

The NZBA was launched in 2021 under the auspices of the UN Environment Programme Finance Initiative as part of the Glasgow effort to marshal private finance behind the goal of limiting global warming. The alliance’s founding cohort—43 banks from 23 countries—committed to align lending and investment portfolios with pathways to net‑zero by 2050 and to set interim 2030 targets. In April 2025 the NZBA membership voted to renew and refocus its mandate, signalling a shift away from purely prescriptive target‑setting towards practical support for banks to finance decarbonisation in the real economy. UNEP FI described that strategic change as intended to bolster implementation tools, sectoral engagement and capacity building, especially for emerging‑market lenders.

UBS’s departure is the latest in a year of high‑profile withdrawals that have dramatically thinned NZBA’s roster. Reuters and other reports list major global banks—including several large US names such as JPMorgan Chase, Citigroup and Morgan Stanley, as well as Macquarie and Bank of Montreal—among those that have left or signalled moves away from the coalition in 2025. Observers and the banks themselves have linked the exodus in part to intensifying political and regulatory scrutiny in some jurisdictions, where elected officials have questioned whether collective climate initiatives overly constrain banks’ commercial responsibilities. Several banks have said they will continue climate work independently while prioritising client and shareholder interests.

The alliance has pushed back against any suggestion that departures undermine its purpose. An NZBA spokesperson said the initiative’s “strength lies in the commitment of its member banks to lead the net zero transition” and emphasised the long‑term nature of the work, which requires “courage, consistency and true leadership.” At the same time, the NZBA has loosened some membership requirements and reconfigured its mandate to remain attractive to a broader and more diverse set of banks, acknowledging the slow pace of change in the real economy and the need for practical implementation support.

UBS itself said the NZBA played a useful role in the early stages of setting targets but that the bank has since “bulked up” its in‑house sustainability capabilities and no longer requires the alliance’s frameworks. The bank’s decision coincides with recent changes in its sustainability leadership: Michael Baldinger stepped down as chief sustainability officer in July 2025 and Christian Leitz was named to add the CSO title to his existing role. UBS said its sustainability strategy and impact are overseen by a board‑level executive, signalling that the firm intends to continue pursuing its net‑zero commitments through internal governance and bespoke client engagement.

Campaigners and some industry analysts warned that the fragmentation of collective mechanisms such as NZBA risks weakening transparency and the comparability of banks’ climate plans. Reuters reported concerns that, without shared standards and reporting expectations, it will be harder to track finance flows and hold firms to account for real‑world emissions outcomes. Proponents of the NZBA’s refreshed approach argue the alliance’s pivot to implementation support and capacity building could nonetheless preserve its relevance by helping smaller and emerging‑market banks to mobilise capital for decarbonisation.

UBS’s exit underlines a broader tension in banking climate policy: the interplay between multilateral, sector‑wide frameworks and individual banks’ desire to set and execute strategies under their own governance amid shifting political pressures. The NZBA and UNEP FI appear to be betting that practical tools, targeted sectoral engagement and support for implementation will keep the alliance useful even as membership evolves. Whether that refocusing will be enough to stabilise confidence in collective standard‑setting and deliver the scale of finance needed for real‑economy decarbonisation remains an open question.
