Low carbon heat

A strategic approach to decarbonising heat
Low carbon heat
Heat is responsible for nearly half of UK carbon emissions yet it is often overlooked. Green Alliance's work has raised awareness of the need for a more strategic approach. Reducing emissions from heat must be a priority for policy makers.

Our November 2016 report with our NGO partners highlights that government progress on heat has lagged behind that of low carbon power, with the potential for policy to drive investment, despite this being at a very early stage.

Switching the UK on to heat pumps
Whilst there is a range of views about how to achieve the deep cuts needed in carbon emissions from heating, all future scenarios indicate there will have to be a significant rise in the uptake of heat pumps.

Our presentation Switching the UK on to heat pumps shows what the government needs to do to encourage more householders and businesses to choose heat pumps. It demonstrates how clever regulation and improving the reputation of heat pumps would be necessary to achieve a mass roll out across the UK.

A manifesto for sustainable heat
Between 2007 and 2010 Green Alliance led a large and unique coalition of businesses, trade associations and parliamentary bodies, concerned about  the need to use and produce heat more sustainably. The resulting 2007 report Manifesto for sustainable heat,, set out solutions supported by 30 organisations.

Advocacy over the three years following the publication of this manifesto influenced the government to launch the Renewable Heat Incentive in 2011.

*Please note that the figures on heat pump performance in the UK on slide 26 refer to system efficiency, not seasonal performance factor (SPF) so are not directly comparable with the German and Swiss trials.
The following SPFs were achieved by domestic heat pumps in a UK field trial:
  • ASHP: 60% of installations with SPFs 1.7 – 2.2 and 30% of installations with SPFs 2.3 – 3.2.
  • GSHP achieved SPFs in the range of <2.0 – 3.2 with 30% of installations with SPFs 2.3 – 3.2.
