A new programme to boost the climate resilience of drought-hit farmers in Iraq. Electricity installations that would give millions across Southern Africa access to clean energy. The conservation of critical ecosystems in Honduras to help local communities improve their livelihoods at home instead of needing to migrate to countries like the United States.

These and hundreds more climate programmes funded by the US government risk disappearing as an administration led by President Donald Trump and tech billionaire Elon Musk threatens to shutter the state aid agency, USAID, and slash overseas development assistance.

“I think this is the end of US [government] climate funding,” predicted Karen Mathiasen, a project director with the Center for Global Development, a Washington-based think-tank. In an interview with Climate Home, she described as “shocking” the speed and brazenness with which the government is attempting to dismantle its foreign aid arm.

Aid organisations and contractors have been grappling with an unprecedented crisis since, on his first day in office, Trump ordered a 90-day funding freeze during which a programme-by-programme review would be carried out.

As the world’s largest bilateral development assistance agency, USAID is a major provider of grant-based finance for climate action in the Global South. Its climate programmes – amounting to close to half a billion dollars in 2024 – help countries cut greenhouse gas emissions and protect their citizens from the escalating effects of global warming.

Secretary of State Marco Rubio – who is now in charge of USAID’s work – said last week that only projects that make “America safer, stronger or more prosperous” will survive the cull, without explaining which criteria would be used for the assessment.

‘Devastating’ consequences

The sudden move has thrown the development world into disarray, with organisations forced to halt their operations overnight and furlough or lay off staff without being able to obtain clear information or guidance from US officials.

Speaking to Climate Home, aid workers involved in USAID-funded climate projects in the Global South painted a picture of bewilderment and confusion.

“We are no longer able to transfer funds to our local partners – and it will be really hard for them to manage costs,” explained one senior official at a global humanitarian group, underscoring the “devastating” consequences of the funding freeze for frontline organisations.

Working in conflict-afflicted regions, the aid group supports projects to build climate resilience that struggle to attract any financing outside of development money, said the official, adding “that has all gone away now”.

“For many programmes a 90-day pause is as good as a cancellation because you lose all momentum, you lose community connection, you lose the trust you built up with communities which is vital to success,” they warned, speaking anonymously due to the sensitivity of the situation.

Separately, in Malawi, Climate Home has learned that all USAID-funded projects have been halted, with staff members being told to remain at home, just as the country was hit by deadly floods last week.

Climate aid powerhouse

Climate Home analysed USAID’s portfolio of climate projects before its website went offline late last week, soon after Trump-ally Musk, the world’s richest man, labelled the agency as “a criminal organisation”, without providing evidence – and called for its closure.

One of USAID’s single largest climate projects supports the large-scale roll-out of clean energy facilities across Southern Africa. With total budgeted funding of $84.5 million up to 2028, the programme aims to set up 3 million new electricity connections and avoid 14 million tonnes of planet-heating emissions – equivalent to the annual carbon footprint of Ivory Coast.

Other large US-backed renewable energy projects target Central Asia, Eastern Europe, Ecuador, Colombia and Bangladesh. The vast majority of these are implemented by profit-making American corporations that would be financially hit by any funding cuts.

Climate adaptation also features prominently in USAID’s portfolio. In the last year alone, the agency committed $22 million to boost the ability of farming communities in Iraq to deal with climate-related drought and $18.5 million to help the adoption of climate resilience measures in Palestine. Similar initiatives have been in place in dozens more countries across the Pacific, South Asia, sub-Saharan Africa and Latin America.

Many other USAID projects include climate-related activities – even if they are not explicitly labelled as such – especially in very fragile and conflict-affected regions.

Adaptation set to suffer

It is impossible to predict what will happen to USAID and its thousands of programmes in what is a fast-changing situation – although many staff are due to be placed on administrative leave at the end of this week amid rumours it will be be folded into the State Department. Any fundamental reforms of the agency, and especially its touted abolition, would legally need to be approved by the Republican-controlled Congress.

But, as far as climate action is concerned, some experts believe the writing is already on the wall.

Along with the wider funding freeze, on his January 20 inauguration day Trump explicitly ordered federal agencies to explain how they would “revoke or rescind” policies implemented to support his predecessor Joe Biden’s international climate finance plan.
