The European Union's climate chief on Saturday heavily criticised an attempt by OPEC to derail a COP28 deal on phasing out fossil fuels, calling the move by the oil producers' club "unhelpful" and "out of whack". Nearly 200 countries meeting in Dubai for the U.N.'s COP28 climate summit are debating whether to agree, for the first time, to eventually end the world's use of fossil fuels, the main cause of climate change. In an unusual intervention, OPEC Secretary General Haitham Al Ghais this week urged countries in the OPEC+ group to reject any COP28 deal targeting fossil fuels, in a letter seen by Reuters.
