4 Min Read BARCELONA (Thomson Reuters Foundation) - Governments must finalise rules for the Paris Agreement on climate change at November’s COP26 summit so the pact can be fully implemented and serve as the basis for a green recovery from the pandemic, the U.N. climate chief said on Monday. As three weeks of virtual climate talks opened, Patricia Espinosa also called on rich nations to fulfil long-standing climate finance pledges to poorer, vulnerable nations in order to secure trust in the U.N.-led process. “It’s time to wrap up outstanding negotiations and implement the Paris Agreement,” said Espinosa, noting that many nations have yet to submit stronger climate action plans that were due last year under the 2015 global accord.
