摘要: 通過(guò)對國際能源機構(IEA)最新公布的各國CO2排放量進(jìn)行分析對比,結果顯示,1990-2005年世界按購買(mǎi)力平價(jià)計算的CO2排放量整體呈下降趨勢,降幅較大,而且在2000年之后基本保持穩定。經(jīng)濟合作與發(fā)展組織(OECD)國家按購買(mǎi)力平價(jià)計算的CO2排放量也有不同程度的減少,非OECD國家按購買(mǎi)力平價(jià)計算的CO2排放量與1990年相比整體上也呈現負增長(cháng),但各國情況相差較大。在人均排放量方面OECD國家普遍高于世界平均水平,而大多數非OECD國家則低于世界平均水平。

Abstract: 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.
Key words: purchasing power parity, OECD, CO2 emission
