Heat pumps
Building emissions may be mitigated by transitioning to heat pumps.
Back to the solutions
- 1/2
- Almost half of building energy use comes from space and water heating.
Emissions
Global greenhouse gas emissions – share of total (2019)
Background
Heat pumps can lead to 50%+ in energy savings compared to conventional heating systems (i.e., commercial electric).
- 50%+
- energy savings with heat pumps.
Up to 3x energy is produced compared to energy consumed by heat pumps.
- 3x
- energy production vs. consumption.

Current State
In 2021, heat pumps supplied only ~10% of heating for all building types.
Global heat pump sales have grown at 11-13% p.a. the past two years, with Europe in particular seeing significant growth as natural gas prices increased.
Policy support has driven significant uptake in countries such as Norway, Sweden, and Finland.
