Registered participants will receive quarterly payments over a period of 15 years. Payments are based on the amount of eligible biomethane that a participant injects into the gas grid. For more information please see the webpage for the Green Gas Support Scheme. 

Greenhouse gases trap heat in the atmosphere. The release of greenhouse gases into the atmosphere is the primary human activity affecting the amount and rate of climate change. The sustainability criteria give a limit on greenhouse gas (GHG) emissions which participants must operate below to remain compliant.
