BELEM, Brazil — As United Nations climate talks bubble to a critical point, negotiators on Tuesday were pressured to ensure that oil — along with fossil fuels coal and natural gas — won’t be burned in the future. Although the conference is scheduled to run through Friday, the Brazilian presidency is pushing for an interconnected decision sooner on four issues. Meanwhile, dozens of nations banded together in a concerted call to deliver a detailed road map for the world to phase out or transition away from fossil fuels. …Much of it will come to a head on Wednesday, the deadline set by COP30 President André Corrêa do Lago for a decision on four issues that were initially excluded from the official agenda: whether countries should be told to toughen their new climate plans; details on handing out $300 billion in pledged climate aid; dealing with trade barriers over climate and improving reporting on transparency and climate progress.
