For the useful heat coming from energy installations delivering heat together with electricity and/or mechanical energy: EC_(h)Eη_(h)(C_(h)η_(h)C_(el)η_(el)C_(h)η_(h)) where: EC_(h,el)= Total greenhouse gas emissions from the final energy commodity. E= Total greenhouse gas emissions of the bioliquid before end-conversion. η_(el)= The electrical efficiency, defined as the annual electricity produced divided by the annual fuel input based on its energy content. η_(h)= The heat efficiency, defined as the annual useful heat output divided by the annual fuel input based on its energy content. C_(el)= Fraction of exergy in the electricity, and/or mechanical energy, set to 100 % (C_(el) = 1). C_(h)= Carnot efficiency (fraction of exergy in the useful heat).
