ROME—The world’s leading economies made no major progress on Sunday over how to cut greenhouse gas emissions, showing how difficult it will be to achieve a breakthrough at United Nations climate talks in Glasgow over the next two weeks.
During a two-day summit in Rome, leaders of the Group of 20 major economies, which includes the U.S., India and China, struggled to find a consensus on how best to adhere to the 2015 Paris climate agreement. The agreement aims to achieve net zero emissions by midcentury, meaning that enough greenhouse gases are removed from the atmosphere to match any new emissions.
