Implementing energy-efficient cooling appliances could avoid nearly eight years of emissions, which is as much as 460 billion tonnes of greenhouse gases. That’s one of the findings of a new report by the United Nations Environment Programme (UNEP) and the International Energy Agency (IEA), which suggests a doubling in energy-efficient air conditioners could bring a saving of $2.9 trillion (£2.3tn) in reduced electricity generation by 2050.
