Eligible technologies

Projects eligible under this methodology are the anaerobic digestion sites where feedstock inputs are collected, anaerobic digestion occurs, and biogas/energy is generated. The Project Developers are the operators of the anaerobic digestion sites.

The only use of biogas eligible in the current version of the methodology is purifying biogas to biomethane and direct injection into the gas grid. Other uses may be considered on a case by case basis, if Project Developers provide sufficient proof that they 1) still adhere to the eligibility criteria and 2) have a rigorous, conservative GHG reduction quantification method for components that differ from the method described in the present document.

The only use of digestate eligible for carbon credits under this methodology is application to agricultural soils as an organic amendment and fertilizer. Such activities shall be credited with avoided synthetic mineral fertilizer production and use. If digestate is used in a different application, the project is still eligible for credits on the basis of their energy production activities.

Project Scope

One project corresponds to one anaerobic digestion site. It is not possible under this methodology to group multiple sites together as one project.

An anaerobic digestion site is defined as a site with one operations permit and shared infrastructure (e.g. digestion tanks, storage, and treatment facilities).

Only the activities at the biogas site that are deemed additional are part of the project scope.
