Rishi Sunak will pledge to spend £1.6 billion ($2 billion) on climate projects, as the British premier arrives at the COP28 summit trying to show leaders the UK remains committed to the cause after he watered down his government’s green agenda and promised to boost oil and gas exploration.

The UK will contribute up to £40 million for the key loss and damage fund to help vulnerable countries cope with the impact of rising temperatures, £500 million to tackle deforestation and about £300 million for energy innovation projects, the government said late Thursday, confirming a Bloomberg News report. Almost half of the £1.6 billion is new funding not included in the UK’s five-year, £11.6 billion climate aid funding pledge which runs to 2026.
