In their own interest, \u201ccoalitions of the willing\u201d of industrialised countries should now step up climate finance for developing countries. <\/p>\n\n\n\n

The aim: to make their climate commitments, which must be updated in 2025 according to the Paris Agreement, as ambitious as possible. Proven CO\u2082 reductions in the Global South should be rewarded with massive public grants \u2013 which would be highly profitable for donor countries due to avoided climate damage. This is the message of an article published today in the top journal Nature, co-authored by Ottmar Edenhofer and Johan Rockstr\u00f6m, scientific directors of the Potsdam Institute for Climate Impact Research (PIK).<\/p>\n\n\n\n

The article points to the inadequate results of the latest world climate summit<\/a> in Azerbaijan, and puts the necessary amount of climate financing at 500 billion dollars annually between 2025 and 2035. That is how much is needed for developing countries to reduce their CO\u2082 emissions in line with the 1.5-degree limit. The article quantifies how this would pay off for donor countries, using the example of a coalition of EU states with the United Kingdom, Norway, Switzerland, Canada, Japan, Australia and South Korea. Their fair share would total 124 billion dollars (0.3 percent of economic output) annually. Based on a conservative estimate of avoided climate damage, the annual return would be 9 percent. Using a generous, scientifically-based estimate, the figure could be over 500 percent.<\/p>\n\n\n\n

\u201cClimate finance is not foreign aid \u2013 it is a high-return investment in global economic stability and climate security for the benefit of all,\u201d the article states. In the past six months alone, climate-related damages from hurricanes Helene and Milton in the US, wildfires in Los Angeles and floods in Valencia in Spain are estimated to exceed 500 billion dollars. And there is the threat of even greater climate damage: \u201cExceeding the 1.5-degree limit makes crossing planetary tipping points more likely, including collapses of ice sheets, ocean currents, coral reefs and permafrost,\u201d warns the research team. \u201cThis would threaten the lives and livelihoods of billions of people.\u201d<\/p>\n\n\n\n
