Climate Change and Carbon Footprint

人类活动所产生的CO2和其他温室气体的排放,导致全球变暖,其实质就是碳足迹日益增大所致。本文通过介绍气候变化、引起气候变化的原因,综述了碳足迹概念、类型、计算方法、边界确定,介绍了PAS2050标准(2008标准),提出了减少碳足迹的措施,旨在了解碳足迹,倡导低碳生活,加强节能减碳的环境意识,实现社会可持续发展。

The emission of CO2 resulting from human activities and other greenhouse gases leads to global warming, the essence of which is the increased carbon footprint. The paper analyses climate change, the reason of climate change, reviews the definition, types, calculation and terms scope of carbon footprint and introduces PAS 2050 standard（2008 standard）. The author then provides measures to reduce carbon footprint, so as to let readers know carbon footprint, advocate low-carbon life, strengthen the belief of saving energy and reducing carbon. By so doing, a society of sustainable development can be realized.
