Hi,
I am wondering how the factor for emissions displaced by AD (Coprods, Cell A45) is calculated. Is there a reference available for the value of 20kgCH4/manure utilized? As this seems to drive RNG from AD emissions it would be helpful to understand how this value was determined.

Also could you confirm that avoided landfill emissions are only calculated for organic waste and no other feedstocks (for RNG)?

There is not a lot of information on this topic. The California Air Resources Board has they values which drive hugely negative emissions for AD RNG but the data in Canada is sparse.

Two references that I have found are
