UK halves Green Climate Fund contribution, as it spends more on security – Image for illustrative purposes only (Image credits: Pexels)
The United Kingdom has told the Green Climate Fund it will deliver only half the amount originally promised for the 2024-2027 period. The reduction forms part of a wider shift that moves resources from international development programs to higher military spending. Officials have described the change as necessary to address security threats, yet the decision has already prompted warnings that other donors may follow the same path.
The Numbers Behind the Cut
Under the previous Conservative government, Britain committed £1.622 billion to the fund for the current replenishment cycle. As of March 2026, only £655 million of that pledge had been transferred. The new total stands at £815 million, a figure confirmed directly to the fund’s secretariat.
The adjustment leaves the Green Climate Fund with roughly $10.149 billion in total resources for the four-year window. All projects already under way remain fully financed, according to a fund spokesperson. Work on new proposals scheduled for board review in 2026 and 2027 is now under reassessment.
| Category | Original Pledge | Revised Amount |
|---|---|---|
| UK contribution (2024-2027) | £1.622 billion | £815 million |
| Amount transferred so far | – | £655 million |
| GCF total resources | – | $10.149 billion |
Expert Views on the Decision
Harjeet Singh, director of the Satat Sampada Climate Foundation, described the move as “moral bankruptcy.” He noted that Britain built its economy on fossil-fuelled industrialisation and therefore carries a particular responsibility to support climate action elsewhere. Liane Schalatek, who follows board meetings for the Heinrich Böll Foundation, called the cut “an unfortunate signal” at a moment when the fund is preparing its next fundraising round.
Fund executive director Mafalda Duarte warned board members in a private note that the shortfall is “expected to have a material impact” on operations over the next two years. She linked the decision to the government’s broader choice to reduce development spending while addressing security concerns.
Why the Shift Occurred
Foreign Secretary Yvette Cooper announced the policy change in March, calling it a “hugely difficult decision” required to deliver the largest defence spending increase since the Cold War. The government has maintained that overseas development assistance will return to 0.7 percent of gross national income once fiscal conditions permit, though no timetable has been given.
Independent analysis by Carbon Brief indicates the real reduction in climate finance is closer to 50 percent once inflation and accounting adjustments are taken into account. The previous Conservative administration had already lowered the overall aid target from 0.7 percent to 0.5 percent of GNI in 2021; the latest step brings it to 0.3 percent.
Potential Ripple Effects
The United States has already withdrawn further contributions and vacated its board seat under the current administration. With the UK’s reduction now public, observers worry that other European donors facing their own budget pressures may also scale back pledges. The fund, established in 2010, has so far supported more than $15 billion in climate projects across developing countries.
Germany and Sweden have urged wealthier developing nations to increase their own contributions, an idea rejected by Saudi Arabia at a recent board meeting. The outcome of these discussions will shape how much new finance the fund can mobilise in the coming replenishment cycle.
What Comes Next
The Green Climate Fund has stated it will continue to maximise impact with existing resources and work with its wide network of partners. For now, the immediate focus remains on protecting approved projects while determining how the reduced UK contribution will affect the pipeline of new initiatives. The episode underscores the growing tension between domestic security priorities and long-standing international climate commitments.
