Rome, 24 July 2021 (dpa/MIA) - The G20 ministers responsible for climate, energy and environment were unable to agree on more ambitious targets for the implementation of the Paris Agreement in talks in Naples on Friday. Several countries rejected committing to keep global warming under 1.5 degrees Celsius in a joint final declaration, said Italian Minister for Ecological Transition Roberto Cingolani after the meeting ended. The countries instead only pledged to the earlier goal in the Paris Agreement of keeping global warming to well below 2 degrees and to continue efforts to reduce it to 1.5 degrees, the declaration said. The Earth has already heated up by around 1.2 degrees compared to pre-industrial times, with fatal climate consequences: Depending on the region, there are more severe weather events including heatwaves, droughts, heavy rain, thunderstorms and floods. The two-day meeting served to prepare for a G20 leaders summit in Rome at the end of October. The Group of 20 economically powerful countries stem from all continents and include the US, China, Russia and Germany. UN climate chief Patricia Espinosa warned that the G20 was responsible for 80 per cent of all global emissions. She called on countries at the COP26 global climate conference planned in Glasgow in November to show determination to succeed.
