Donald Trump said on Wednesday that if elected he would renege on a $3 billion US pledge to a global fund meant to help developing countries cut emissions and adapt to climate change.
The pledge was announced by Vice President Kamala Harris this month at the COP28 climate summit, although it is subject to the politically divided US Congress, which must authorise the release of funds.
Trump, who has made attacking the administration of President Joe Biden's investments in renewable energy a core part of his campaign message, said he was opposed to what he called "climate reparations" to other countries.
A campaign aide confirmed that Trump was referring to the $3 billion US pledge to the Green Climate Fund.
"When I am back in office all climate reparation payments will be cancelled immediately," Trump said at a campaign event in Coralville, Iowa, adding he would seek to "claw back" any payments made by the Biden administration.
Trump leads his rivals for the Republican nomination by nearly 50 percentage points in national opinion polls, meaning he is likely to face Biden, the presumptive Democratic Party nominee, in the November 2024 election.
