Poorer nations need $1tn a year by 2030 in climate finance, top economists find

Study says funding to cope with climate breakdown needed five years earlier than expected

Poor countries need $1tn a year in climate finance by 2030, five years earlier than rich countries are likely to agree to at UN climate talks, a new study has found.

Waiting until 2035 to receive the funding, which is to help them cut greenhouse gas emissions and cope with extreme weather, would place damaging burdens on vulnerable countries, warned the Independent High-Level Expert Group on Climate Finance, a group of leading economists.
