The countries participating in the UN Climate Change Conference (COP30), currently taking place in Brazil, must cancel fossil fuel concessions in order to keep the Paris Agreement alive. This is the main message of a paper published in the journal Nature and signed by experts Martí Orta, Gorka Muñoa and Marcel Llavero, from the Faculty of Biology and the Biodiversity Research Institute (IRBio) of the University of Barcelona, and Guillem Rius, from the Barcelona Institute for Global Health (ISGlobal).
Committing to renewable energy
As the experts point out in Nature magazine, the Paris Agreement requires countries to work to limit global warming to well below 2°C and to make efforts to limit it to 1.5°C, in order to avoid climate tipping points with devastating consequences.
"This latter objective requires drastic action, even if we assume a temporary overshoot 1.5°C and later reduce atmospheric carbon concentrations to lower temperatures, the most optimistic scenario for most climate scientists," says the team, which also participated in COP29 in 2024, held in Azerbaijan.
