The world will need more than 10 billion new cooling appliances by 2050, according to a recent estimate. That would take the total up to around 14 billion such machines in a warming world. An estimated 3.6 billion appliances are currently in use. This number, however, is increasing by up to 10 cooling appliances every second, said the Cooling Emissions and Policy Synthesis Report: Benefits of cooling efficiency and the Kigali Amendment report released July 17, 2020. At this rate, the world will have four times more or at least 14 billion cooling appliances by 2050, contributing significantly to rising temperatures, the report by the UN Environment Programme (UNEP) and the International Energy Agency (IEA) pointed out.
