This call for evidence will inform the Green Gas Support Scheme’s annual tariff review 2024. It's open from 29 April to 27 May 2024. 

We're seeking views on the outlook of the biomethane industry and whether costs and revenues for biomethane plants have changed over the past year.

We invite responses from industry, investors, trade associations and other stakeholders.

Your evidence will help to ensure that tariffs are set an appropriate level.
