HSBC has officially withdrawn from the United Nations (UN)-backed Net-Zero Banking Alliance (NZBA), becoming the first major UK bank to do so. This decision has sparked debate across the financial world — is this a step toward climate pragmatism, or a retreat from accountability? As more banks question the value of collective climate commitments, the rise of AI in sustainability could reshape the net-zero journey altogether.
In July 2025, HSBC announced its decision to exit the NZBA. The bank cited a need to pursue an “independent, science-based approach” to climate targets, stating that the alliance’s framework no longer aligned with its operational priorities.
However, the move coincided with:
Critics argue this signals a worrying retreat. Supporters say it’s a pragmatic shift. Either way, HSBC’s exit reopens the debate on how best to manage climate accountability in finance.
Banks are leaving alliances like the NZBA because of increasing legal, political, and reputational risks. Some financial institutions believe they can pursue decarbonisation more flexibly and efficiently outside of collective frameworks — though this can lead to weaker public accountability.
HSBC’s move follows a wider trend of banks distancing themselves from climate coalitions:
The NZBA, once a gold standard for climate alignment in finance, has lost more than a dozen members in just six months. While some cite political uncertainty and litigation risks, others simply view the alliance as too rigid for global business models.
The NZBA is a UN-backed initiative that brings together global banks committed to achieving net-zero greenhouse gas emissions from their lending and investment portfolios by 2050. Members are expected to set science-based targets and regularly report progress.
HSBC is currently the only UK bank to exit the NZBA. Other major players — including Barclays , NatWest Group , Lloyds Banking Group , and Standard Chartered — remain members.
However, HSBC’s decision may embolden other banks to reconsider their climate commitments, especially as alliances loosen requirements. If more UK banks withdraw, this could:
Yes, most UK banks remain committed to net-zero goals — but strategies vary. While alliances like the NZBA provide shared standards, many banks are now developing internal frameworks and using tools like AI to guide their decarbonisation plans independently.
Unlike the UK and North America, no major EU bank has left the NZBA to date. European institutions such as BNP Paribas, ING, and Deutsche Bank continue to operate within the framework, supported by the EU Green Deal and stricter climate regulations.
But cracks are beginning to show. In April 2025, NZBA relaxed its core requirement to align with the 1.5°C target. While framed as flexibility, this could signal future defections — especially if political winds shift in key EU countries.
European banks often lead in sustainability reporting due to stricter EU regulation and public expectations. However, commitment levels vary, and ongoing policy shifts may influence future participation in alliances like the NZBA.
The NZBA’s credibility has taken a hit:
In response, the NZBA has pivoted toward:
Still, its declining membership raises the question: can alliances like NZBA still drive change, or are they becoming symbolic?
Alliances like the NZBA help set common standards and promote transparency. However, with advances in sustainability technology — especially AI — many banks now have the tools to manage climate performance independently and with greater precision.
As public frameworks like the NZBA lose members and loosen requirements, AI is quickly becoming the financial sector’s most powerful tool for meeting net-zero targets. Unlike alliances that rely on public pledges and voluntary reporting, AI enables real-time, data-driven accountability.
Net zero isn’t just about setting a target — it’s about tracking, forecasting, and acting at scale. That’s where AI shines.

AI accelerates net zero by automating emissions tracking, evaluating climate risk, and monitoring the performance of green finance products in real time. This gives banks the data they need to reduce financed emissions and prove impact — without relying solely on alliances.
HSBC’s departure from the NZBA is more than a symbolic move. It marks a shift toward individualised climate strategies, increased corporate discretion, and growing reliance on technology over policy.
Whether this leads to progress or backsliding depends on how effectively banks deploy new tools — especially AI — to uphold net-zero ambitions.
For investors, policymakers, and the public, one thing is clear: the next phase of climate finance will not be decided in UN committees alone — it will be shaped in algorithms, models, and AI-powered decisions made in real time.
HSBC’s exit may signal a broader move away from collective climate commitments and toward tech-driven, individual strategies. The future of sustainable finance will depend on how well financial institutions balance flexibility with transparency — and how effectively they use AI to stay accountable.
