Global Renewable and Low-Carbon Gas Report 2021

While current biogas and biomethane production is only around 35 Mtoe, total sustainable production potential is estimated to be over 20 times that level at 730 Mtoe (8,500 TWh).8 At this potential level, if all biogas were upgraded to grid quality9, biomethane could provide around 20% of today’s natural gas demand, providing a significant decarbonisation benefit reducing global emissions by around 1.5 Gt CO2 e. However, that also requires a very rapid build-up of biomethane production capacity.
