UBS Exits Climate Alliance Despite Maintaining Green Pledge
The world of sustainable finance is undergoing a significant transformation, as several major banks are distancing themselves from collective climate initiatives while maintaining their strong environmental commitments.
The Great NZBA Exodus
Throughout 2025, prominent financial institutions including UBS have been withdrawing from the United Nations-backed Net Zero Banking Alliance (NZBA). This trend has sparked considerable debate about the future of coordinated climate action within the banking sector.
Despite these high-profile departures, the banks involved maintain that their dedication to sustainability hasn't waveredâthey're simply changing their approach.
UBS Charts Its Own Course
UBS became the latest major bank to leave the alliance, but the Swiss giant insists its sustainability leadership remains intact.
The bank has built its environmental strategy around three key areas: protect, grow, and attract. This framework integrates climate considerations throughout its global operations while putting clients at the centre of its approach to supporting low-carbon transition.
As one of the NZBA's founding members in 2021, UBS joined during the early days when the finance industry was still developing frameworks for measuring financed emissions. Now, with stronger internal capabilities and established groundwork, the bank has decided to go it aloneâfollowing the lead of several industry peers.
"With that work advanced and with our in-house capabilities strengthened, we have decided to withdraw from the NZBA, like a number of our global peers," UBS stated officially. "Our commitment to sustainability remains unchanged and we recognise the importance of an orderly transition to a low-carbon economy."
Rather than retreating from environmental goals, UBS views this as a strategic shift towards greater independence and operational flexibility. The bank continues to focus on long-term climate impact through informed investments and comprehensive stress-testing.
As UBS Chairman Colm Kelleher and Group CEO Sergio P. Ermotti explained in the bank's 2024 Sustainability Report: "Our sustainability and impact strategy is based on three strategic pillars: Protect, Grow and Attract."
Barclays Takes a Similar Path
Barclays has also departed the NZBA while reaffirming both its net zero by 2050 commitment and ambitious goal to mobilise US$1tn in climate finance.
"With the departure of most of the global banks, the organisation no longer has the membership to support our transition," Barclays explained in its formal statement.
Even after leaving the alliance, Barclays continues to prioritise several key areas:
- Supporting client decarbonisation strategies
- Financing clean energy and climate innovation
- Scaling transition finance solutions
- Enabling secure, sustainable energy systems
The bank's commitment appears to be paying off financially too. In 2024, Barclays reported approximately ÂŁ500,000 in revenue from sustainable and transition finance activitiesâa sign of both growing demand and profitability in green finance.
Understanding the Alliance's Decline
The NZBA launched in 2021 as part of the Glasgow Financial Alliance for Net Zero (GFANZ), initially bringing together 43 institutions committed to aligning their banking portfolios with the Paris Agreement. At its height, membership swelled to 144 banks controlling US$42tn in assets.
However, the alliance's recent decision to weaken its requirementsâshifting from mandatory interim targets to non-binding recommendationsâhas triggered a mass exodus. Critics argue this change has seriously damaged the NZBA's credibility and ambition.
Triodos Bank captured this sentiment perfectly: "Remaining a member under these less stringent guidelines and seeing what we have achieved over the years being watered down, would not align with our own climate ambition and commitment to combatting climate change."
A Sector at the Crossroads
The wave of departures from global climate alliances exposes a fundamental tension in sustainable finance: the balance between collaborative governance and operational independence, between public accountability and strategic flexibility.
HSBC, another 2025 departure, cited the need to concentrate on its internal net zero roadmap—though this came alongside delays to key climate targets and changes to executive incentives. The situation has been further complicated by political pressure, including pushback from US lawmakers and renewed support for fossil fuel expansion.
The Path Forward
What's becoming clear is that leading banks aren't abandoning their climate commitments—they're simply recalibrating how they deliver them.
Whether through developing their own frameworks or enhancing stakeholder engagement, institutions like UBS and Barclays are pursuing more customised, agile approaches. They remain committed to helping clients transition to a net zero economy, but they want to do it on their own terms.
The question now is whether this shift towards individual action will prove more effective than collective efforts, or whether it signals a broader retreat from coordinated climate action in the financial sector.
