Abstract:
We developed a bottom-up emission inventory for Chinese rural residential sector. Emissions are estimated with an empirical model which established the relationship between solid fuel-use pattern and meteorological, geographic, and income factors for rural residential households in China using the ~17,000 samples collected by questionnaire survey in 2010. At the same time, an improved emission factors database is also compiled in this work by collecting most recent local measurements. Driven by the increase of income, household residents prefer to choose fossil fuel than biofuel. The estimated aggregated consumptions of coal and crop residues for rural residential are higher by 58% and lower by 47% compare to the official energy statistics, respectively. Emissions from China’s rural residential sector in 2010 are estimated to be 2.2 Tg SO2, 0.4 Tg NOx, 40.0 Tg CO, 2.1 Tg NMVOC, 3.1 Tg PM2.5, 0.5 Tg BC and 1.2 Tg OC respectively. The developed inventory improves the fuel consumption data availability for rural residential and represent the differences in fuel use patterns among provinces. This work is important to understand the characteristics of rural residential fuel activities and emissions by providing the valuable first-hand solid fuel-use pattern data for rural residential in China and will be helpful to improve the accuracy of bottom-up emission inventory over China.
