LPG: carbon footprint per litre
Live factor value
1.56 kgCO2e per litre
Source: UK DESNZ greenhouse-gas conversion factors, 2026 (revision 2). Factor set desnz-2026-r2.
LPG (liquefied petroleum gas) fuels heating and cooking in many off-grid homes and businesses. The official UK emission factor is published per litre in the DESNZ 2026 conversion factors, shown live below, so bottle sizes and tank top-ups convert straight into kgCO2e.
Per unit of heat, LPG sits between mains gas and heating oil in carbon intensity. If you buy LPG by the kilogram rather than the litre, roughly 1.96 litres make a kilogram — or use the calculator, which handles the unit for you.
Worked example
One 47 kg propane cylinder (~92 litres): 92 × 1.56 = 143 kgCO2e.

Frequently asked questions
- Is LPG lower-carbon than heating oil?
- Per kWh of heat, yes — LPG emits somewhat less CO2e than burning oil, though more than mains natural gas. The per-litre figures differ partly because the fuels have different energy densities.
