Heat pumps are a proven way to provide secure and sustainable heating 

Heat pumps, powered by low‐emissions electricity, are the central technology in the global transition to secure and sustainable heating. Heat pumps currently available on the market are three‐to‐five times more energy efficient than natural gas boilers. They reduce households’ exposure to fossil fuel price spikes, which has been made all the more urgent by the ongoing global energy crisis. Over one‐sixth of global natural gas demand is for heating in buildings – in the European Union, this number is one‐third. Many heat pumps can provide cooling, too, which eliminates the need for a separate air conditioner for the 2.6 billion people who will live in regions requiring heating and cooling by 2050. Heating in buildings is responsible for 4 gigatonnes (Gt) of CO2 emissions annually – 10% of global emissions.

Installing heat pumps instead of a fossil‐fuel‐based boilers significantly reduces greenhouse gas emissions in all major heating markets, even with the current electricity generation mix— an advantage that will increase further as electricity systems decarbonise.
