The greenhouse gas intensity of excess useful heat or excess electricity is the same as the greenhouse gas intensity of heat or electricity delivered to the fuel production process and is determined from calculating the greenhouse intensity of all inputs and emissions, including the feedstock and CH4 and N2O emissions, to and from the cogeneration unit, boiler or other apparatus delivering heat or electricity to the fuel production process.
Is ionann déine astaíochtaí gás ceaptha teasa an fharasbairr teasa úsáidigh nó an fharasbairr leictreachais agus déine astaíochtaí gás ceaptha teasa an teasa nó an leictreachais arna sheachadadh chuig an bpróiseas táirgeachta breosla agus déantar é a chinneadh ón ríomh ar dhéine astaíochtaí gás ceaptha teasa ó gach ionchur agus gach astaíocht, lena n-áirítear an bunábhar agus astaíochtaí CH4 agus N2O, chuig agus ón aonad comhghiniúna, coire nó fearas eile a sheachadann teas nó leictreachas chuig an bpróiseas táirgeachta breosla.
