COP26 summit:Global leaders promise to end deforestation by 2030

More than 100 world leaders have promised to end and reverse deforestation by 2030, in the COP26 climate summit's first major deal. Brazil, where stretches of the Amazon rainforest have been cut down, was among the signatories on Tuesday. The pledge includes almost $19.2bn of public and private funds. The countries who have signed the pledge - including Canada,Russia, China, Indonesia, the Democratic Republic of the Congo, the US and the UK among others - cover around 85% of the world's forests. Governments of 28 countries also committed to remove deforestation from the global trade of food and other agricultural products such as palm oil, soya and cocoa. More than 30 of the world's biggest financial companies have also promised to end investment in activities linked to deforestation..

England Prime Minister Boris Johnson, who is hosting the global meeting in Glasgow, said,more leaders than ever before, a total of 110, had made the landmark commitment. "We have to stop the devastating loss of our forests," he said - and "end the role of humanity as nature's conqueror, and instead become nature's custodian". Experts welcomed the move, but warned a previous deal in 2014 had failed to slow deforestation at all and commitments needed to be delivered on. Felling trees contributes to climate change because it depletes forests that absorb vast amounts of the warming gas CO2.The two-week summit in Glasgow is seen as crucial if climate change is to be brought under control.
