西北地区居民生活碳排放结构及其影响因素

为揭示西北地区居民家庭生活碳排放现状与规律, 基于家庭生活碳排放相关数据的调查, 综合利用《IPCC国家温室气体清单指南(2006)》、《中国温室气体清单研究》、投入产出分析方法和生命周期评价方法, 对西北地区居民家庭生活碳排放情况进行了评估分析. 研究发现: 西北地区人均生活碳排放只有2.05 tCO₂/(人 年); 生活碳排放主要来源于煤炭、电力和食品消费, 化石燃料消费所产生的直接碳排放占39.29%, 电力等家庭消费活动所产生的间接碳排放占60.71%; 生活碳排放主要受地理环境、家庭规模、经济收入、年龄结构等因素影响, 不同省区和城乡人口之间的排放量存在一定差别.

Household carbon emission differences and their driving factors in Northwestern China

Based on interview survey data, we used the 2006 IPCC Guidelines for National Greenhouse Gas Inventories, the People's Republic of China National Greenhouse Gas Inventory(2007), input-output analysis, and life cycle assessment methodology to assess household CO₂ emissions in Northwestern China. The result revealed the status and patterns of household CO₂ emissions in this area: (1) average annual household CO₂ emission per capita is 2.05 tons CO₂ per year; (2) the majority of household CO₂ emissions came from coal, electricity and food consumption, in which direct CO₂ emissions (related to consumption of fossil fuel) accounted for 39.29 percent, and indirect emissions comprised 60.71 percent; (3) household CO₂ emission was mainly affected by geographic environment, family size and income, and household age structure; (4) amounts, sources and driving factors of CO₂ emission varied between urban and rural households, as well as between households in different provinces.
