By introducing a CHP, a reduction of 32.6 tonnes of CO₂ emissions (32,626/203,143 = 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) =(252,044 kWh x 0.519) + (334,871 kWh x 0.216) = 203,143 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) =(399,827 kWh x 0.216) + (61,956 kWh x 0.216) + (252,044 kWh x 0.519) - (115,681 kWh x 0.519) = 170,517 kg CO₂ pa
