It is a vicious cycle – as the climate grows hotter, demand for air conditioning is booming and that is helping make the climate even hotter.
Air conditioning accounts for about a fifth of the total electricity used in buildings around the world. Much of that electricity comes from power stations giving off greenhouse gases, and to make matters worse, air conditioners can also leak hydrofluorocarbon refrigerants, greenhouse gases thousands of times more powerful than carbon dioxide over a 20-year period.
