Abstract:

According to survey data of 72 heating enterprises in Shenyang city, the carbon emission of heating enterprises was calculated by using the methodology of IPCC greenhouse gases inventory. The results show that the carbon emission intensity was significantly different in various heating sources during the 151 d heating period. The carbon emission intensity in scattered small boiler room, regional boiler room, combined heat and power generation (CHP), combined heating sources (coal-fired boiler and heat pump), and clean energy heating was 58.25 kg CO₂/m², 53.42 kg CO₂/m², 49.87 kg CO₂/m², 34.49 kg CO₂/m² and 21.58 kg CO₂/m², respectively. Based on the carbon emission intensity of different heating sources and baseline determination methods recommended by clean development mechanism (CDM), six kinds of baseline scenarios were set, including actual emission, historical emission, >40 t/h regional boiler room emission, CHP emission, and the emission from the top 30% and 40% enterprises on the technical level. Through comparing various carbon emission baseline values, combining economic and technological development level, and carbon trading market plan, the carbon emission of the top 40% enterprises on the technical level (46.57 kg CO₂/m²) was recommended as the carbon emission baseline of heating industry in 2013 in Shenyang city. The carbon emission baselines from 2014 to 2020 were also forecasted.
