Grid Carbon Factor
grams of CO2e/KWh
Carbon Grid Factors have fallen by more than half since 2014, and are due to halve again by 2035.
The solid blue line shows the Grid Carbon Factor in gCO2
e/KWh falling steadily between 2014 and 2035.
The dotted blue line shows the projections made a year earlier by BEIS.
Graph shows data from DEFRA for 2014 to 2016 and projections to 2035 published by BEIS in January 2018.
The case for using ground source heat pumps to limit climate change gets stronger and stronger every year.
