Avoided annual COâ‚‚ emissions from heat pump sales worldwide 2019-2023, by country
The United States is the largest contributor to heat pump-related emission reductions, with ** MtCO₂ avoided annually over the five-year period from 2019 to 2023. In total, heat pumps for space and water heating installed since 2019 avoid around ** MtCO₂ annually. In 2023, global heat pump sales decreased by three percent year-on-year.
