Displaying the CO2 released from different heating technologies. GSHP values are for 2 typical levels of efficiency; 320% (COP=3.2) & 400% (COP=4). Grid carbon intensity uses real-time data. The value reflects the decline in generation from coal & the growing contribution from renewable power technologies.
