Citigroup confirmed on 31 December 2024 that it had withdrawn from the Net-Zero Banking Alliance, the United Nations-convened industry group that requires member banks to align their lending portfolios with a net-zero emissions pathway by 2050. The departure makes Citi one of several large US lenders to exit the coalition in December, following similar moves by Goldman Sachs and Wells Fargo earlier in the month.
The exit marks a notable reversal for a bank that was among the NZBA's founding signatories when the alliance launched in April 2021. At the time, Jane Fraser — who had assumed the chief executive role just weeks earlier — made the net-zero financing target a centrepiece of her opening statement, positioning Citi's climate commitments as a strategic priority alongside its broader transformation programme.
A FOUNDING MEMBER STEPS BACK
The NZBA was established under the umbrella of the Glasgow Financial Alliance for Net Zero, the broader coalition chaired by former Bank of England Governor Mark Carney that brings together asset managers, insurers, and banks behind a shared low-carbon transition agenda. Membership of the banking sub-group carries specific obligations, including setting interim 2030 financed-emissions targets across a range of high-emitting sectors and publishing annual progress reports aligned with a 1.5-degree warming scenario.
Critics of the alliance have long argued that those obligations create legal exposure in jurisdictions where antitrust regulators scrutinise co-ordination among competitors on business decisions, including lending criteria. US Republican-led states have also intensified political pressure on financial institutions over what they characterise as the imposition of ideological climate criteria on capital allocation, adding to the reputational and legislative risk calculations that bank boards must weigh.
Citi stated that it would maintain its commitment to the Glasgow Financial Alliance for Net Zero despite withdrawing from the banking-specific sub-group. The distinction matters: GFANZ itself imposes fewer prescriptive requirements on individual members and carries a broader, more flexible mandate than the NZBA's sector-by-sector target-setting framework.
CLIMATE STRATEGY UNDER RENEWED SCRUTINY
The wave of US bank departures from the NZBA in the final weeks of 2024 raises questions about the alliance's long-term composition and influence, particularly given that several of the world's largest financiers of carbon-intensive industries are concentrated in the United States. The NZBA was designed partly as a mechanism to redirect private capital towards climate-aligned assets at the scale needed to meet international temperature goals — a task that becomes more complicated as major signatories exit.
For Citi, the practical implications of the withdrawal on its day-to-day lending and capital-markets activity remain to be clarified. The bank has published financed-emissions data and set sector-level targets in prior years, and it has not indicated whether those internal frameworks will be unwound or continued on a voluntary basis outside the NZBA's reporting infrastructure.
Climate-focused investors and non-governmental organisations are expected to press Citi and other departing institutions for detailed explanations of how their climate governance will operate absent the external accountability structure that NZBA membership provided. The broader trajectory of US bank participation in international climate coalitions will be closely watched as the incoming political environment in Washington shapes the regulatory and reputational landscape for environmental commitments across the financial sector.
