能源部门是重要的温室气体排放源。据估算,全球化石燃料燃烧排放的CO_2量占人类活动引起的CO_2总的净排放量的60%以上;约占总排放量50%的NO_x和26%的CO也来自化石燃料的燃烧。同时,在煤矿开采和油气生产过程中,还排放了约占全球总排放量20%左右的CH_4。因此,未来世界能源的发展对全球温室气体的排放将起着重要的作用。
The energy sector is an important source of greenhouse gas emissions. It has been estimated that the amount of CO2 emitted from global fossil fuel combustion accounts for more than 60% of the total net CO2 emissions from human activities; about 50% of the total NOX emissions and 26% of CO also come from the combustion of fossil fuels. At the same time, CH_4, which accounts for about 20% of the total global emissions, was also emitted during coal mining and oil and gas production. Therefore, the future development of world energy will play an important role in the global greenhouse gas emissions.
