In the case of co-digestion of n substrates in a biogas plant for the production of electricity or biomethane, actual greenhouse gas emissions of biogas and biomethane are calculated as follows: E / 1S_(n)(e_(ec,n)e_(td,feedstock,n)e_(l,n)e_(sca,n))e_(p)e_(td,product)e_(u)e_(ccs)e_(ccr) where E= total emissions from the production of the biogas or biomethane before energy conversion; S_(n)= Share of feedstock n, in fraction of input to the digester; e_(ec,n)= emissions from the extraction or cultivation of feedstock n; e_(td,feedstock,n)= emissions from transport of feedstock n to the digester; e_(l,n)= annualised emissions from carbon stock changes caused by land-use change, for feedstock n; e_(sca)= emission savings from improved agricultural management of feedstock n (*); e_(p)= emissions from processing; e_(td,product)= emissions from transport and distribution of biogas and/or biomethane; e_(u)= emissions from the fuel in use, that is greenhouse gases emitted during combustion; e_(ccs)= emission savings from CO_(2) capture and geological storage; and e_(ccr)= emission savings from CO_(2) capture and replacement. For e_(sca) a bonus of 45 g CO_(2)eq/MJ manure shall be attributed for improved agricultural and manure management in the case animal manure is used as a substrate for the production of biogas and biomethane.
