British government said that dates for a rescheduled conference in 2021 would be announced later. Some 30,000 people, including 200 world leaders, had been due to attend the 10-day conference for crucial talks to halt rising global temperatures.
A UN panel in 2018 concluded that avoiding global climate chaos needed a major shift in society and the world economy. Global CO2 emissions needed to drop 45 per cent by 2030 and reach net zero by 2050, to limit temperature rise to the safe cap of 1.5 degrees Celsius set as a goal in the Paris accord.
UN Climate Change Executive Secretary Patricia Espinosa said postponement was unavoidable but that the pandemic should not divert the world from the climate change challenge.
