世界主要CO2排放国家和地区的排放状况及对比分析

 通过对国际能源机构（IEA）最新公布的各国CO2排放量进行分析对比，结果显示，1990-2005年世界按购买力平价计算的CO2排放量整体呈下降趋势，降幅较大，而且在2000年之后基本保持稳定。经济合作与发展组织（OECD）国家按购买力平价计算的CO2排放量也有不同程度的减少，非OECD国家按购买力平价计算的CO2排放量与1990年相比整体上也呈现负增长，但各国情况相差较大。在人均排放量方面OECD国家普遍高于世界平均水平，而大多数非OECD国家则低于世界平均水平。

Comparisons of CO2 Emission from Fuel Combustion Among Major Countries and Regions

Based on latest national CO2 emissions data released from the International Energy Agency (IEA), using the statistical method, the CO2 emission trends for different countries and regions were analyzed. The results show that the CO2 emission of the whole world based on purchasing power parity (PPP) decreased from 1990 to 2005, with larger reduction amplitude; and after 2000, the emission amount kept basically constant. The CO2 emission from OECD countries also decreased to different extent. The CO2 emission from non-OECD countries overally had a negative growth rate, but differences in CO2 emissions were still very large from country to country. The per capita CO2 emissions from OECD countries were generally higher than the world average level, while those from most of non-OECD countries were lower than the world average level.
