中國(guó)是世界上最大的能源消費(fèi)國(guó)和二氧化碳排放國(guó)。城市占中國(guó)二氧化碳排放總量的85％，因此城市被視為實(shí)施旨在適應(yīng)氣候變化和減少二氧化碳排放的政策的關(guān)鍵領(lǐng)域。然而，由于缺乏系統(tǒng)的統(tǒng)計(jì)數(shù)據(jù)以及現(xiàn)有數(shù)據(jù)質(zhì)量較差，中國(guó)城市的排放清單建設(shè)尚未得到很好的研究。針對(duì)這一研究差距，作者基于能量平衡表制定了一套中國(guó)城市二氧化碳排放清單的方法。新建的排放清單是根據(jù)IPCC地區(qū)排放核算方法提供的定義編制的，涵蓋47個(gè)社會(huì)經(jīng)濟(jì)部門，17個(gè)化石燃料和9種基礎(chǔ)工業(yè)產(chǎn)品，與國(guó)家和省級(jí)清單相對(duì)應(yīng)。在這項(xiàng)研究中，作者應(yīng)用這些方法編制了24個(gè)中國(guó)普通城市的二氧化碳排放清單，并檢查了清單的不確定性。了解中國(guó)城市的排放源是未來許多氣候政策和目標(biāo)研究的基礎(chǔ)。

China is the world's largest energy consumer and CO2 emitter. Cities contribute 85% of the total CO2 emissions in China and thus are considered as the key areas for implementing policies designed for climate change adaption and CO2 emission mitigation. However, the emission inventory construction of Chinese cities has not been well researched, mainly owing to the lack of systematic statistics and poor data quality. Focusing on this research gap, we developed a set of methods for constructing CO2 emissions inventories for Chinese cities based on energy balance table. The newly constructed emission inventory is compiled in terms of the definition provided by the IPCC territorial emission accounting approach and covers 47 socioeconomic sectors, 17 fossil fuels and 9 primary industry products, which is corresponding with the national and provincial inventory. In the study, we applied the methods to compile CO2 emissions inventories for 24 common Chinese cities and examined uncertainties of the inventories. Understanding the emissions sources in Chinese cities is the basis for many climate policy and goal research in the future.
