Experts call for new taxes on worst polluters to help poorer nations with climate crisis

Report to be discussed at Cop30 says global agreements should target carbon intensive activities and ‘ultra high net worth individuals’

The roadmap will form the basis of discussions of climate finance at Cop30. Last year’s “conference of the parties” in Baku set a goal of £1.3tn to be provided annually to poor countries by 2035, to help them cut greenhouse gas emissions and cope with the impacts of extreme weather. But there was a bitter taste for many when rich countries pledged to stump up only $300bn of that sum, leaving the rest to come from potential new taxes and levies, the private sector, and related sources.
