燃料燃烧和二氧化碳排放的高分辨率制图为污染物运输建模、制定缓解政策以及二氧化碳通量的逆建模提供了有价值的信息。以前的全球排放图只包括几种燃料类型，排放量是通过人口密度图按人均平均分配国家燃料数据在网格上估计的。这一过程扭曲了各国内部排放的地理分布。在本研究中，采用次国家分类方法（SDM）对燃料数据进行分类，以64种燃料类型为基础，建立了2007年全球0.1 × 0.1地理参考燃料燃烧（PKU-FUEL）和相应的二氧化碳排放（PKU-CO2）清单。利用蒙特卡罗方法对发射图的不确定性进行了评估。据估计，2007年包括化石燃料、生物质和固体废物在内的燃烧源的CO 2排放量为11.2 Pg C yr - 1（第5和第95百分位数分别为9.1 Pg C yr - 1和13.3 Pg C yr - 1）。其中，化石燃料燃烧的排放量为7.83 Pg C / yr - 1，这与国际能源机构的估计（7.87 Pg C / yr - 1）非常接近。在本研究中，通过用次国家数据取代国家数据分解，所有网格点的co2排放的平均95 - 5百分位范围可以从417 Mg km−2 yr−1减少到68.2 Mg km−2 yr−1。由于直接使用次国家燃料消耗数据可以更好地考虑到国家内部人均燃料消耗的不均匀分布，因此这种差距会缩小。在发展中国家，城市和农村地区的人均二氧化碳排放量存在显著差异（2.08 vs 0.598 Mg C/(cap)）。))，但在发达国家则不然（3.55毫克/毫克vs. 3.41毫克/毫克/毫克）。×年))。这意味着发展中国家的快速城市化很可能在未来推高它们的排放量。
High-resolution mapping of fuel combustion and CO2 emission provides valuable information for modeling pollutant transport, developing mitigation policy, and for inverse modeling of CO2 fluxes. Previous global emission maps included only few fuel types, and emissions were estimated on a grid by distributing national fuel data on an equal per capita basis, using population density maps. This process distorts the geographical distribution of emissions within countries. In this study, a sub-national disaggregation method (SDM) of fuel data is applied to establish a global 0.1 × 0.1 geo-referenced inventory of fuel combustion (PKU-FUEL) and corresponding CO 2 emissions (PKU-CO2) based upon 64 fuel sub-types for the year 2007. Uncertainties of the emission maps are evaluated using a Monte Carlo method. It is estimated that CO 2 emission from combustion sources including fossil fuel, biomass, and solid wastes in 2007 was 11.2 Pg C yr −1 (9.1 Pg C yr −1 and 13.3 Pg C yr −1 as 5th and 95th percentiles). Of this, emission from fossil fuel combustion is 7.83 Pg C yr −1, which is very close to the estimate of the International Energy Agency (7.87 Pg C yr −1). By replacing national data disaggregation with sub-national data in this study, the average 95th minus 5th percentile ranges of CO 2 emission for all grid points can be reduced from 417 to 68.2 Mg km −2 yr−1. The spread is reduced because the uneven distribution of per capita fuel consumptions within countries is better taken into account by using sub-national fuel consumption data directly. Significant difference in per capita CO 2 emissions between urban and rural areas was found in developing countries (2.08 vs. 0.598 Mg C/(cap. × yr)), but not in developed countries (3.55 vs. 3.41 Mg C/(cap. × yr)). This implies that rapid urbanization of developing countries is very likely to drive up their emissions in the future.
