By introducing a CHP, a reduction of 25.6 tonnes of CO₂ emissions (25,561/159,608 = 16%) could be expected relative to a conventional mains supply/gas boiler system. Notes: (a) = (electricity consumption x 0.519) + (gas consumption x 0.216) =(198,036 kWh x 0.519) + (263,089 kWh x 0.216) = 159,608 CO₂ pa (b) = (CHP gas consumption x 0.216) + (supporting boiler gas consumption x 0.216) + (electricity consumption x 0.519) - (CHP electricity production x 0.519) =(318,545 kWh x 0.216) + (44,725 kWh x 0.216) + (198,036 kWh x 0.519) - (90,945 kWh x 0.519) = 134,047 kg CO₂ pa
