Abstract
Despite China’s emissions having plateaued in 2013, it is still the world’s leading energy consumer and CO2 emitter, accounting for approximately 30% of global emissions. Detailed CO2 emission inventories by energy and sector have great significance to China’s carbon policies as well as to achieving global climate change mitigation targets. This study constructs the most up-to-date CO2 emission inventories for China and its 30 provinces, as well as their energy inventories for the years 2016 and 2017. The newly compiled inventories provide key updates and supplements to our previous emission dataset for 1997–2015. Emissions are calculated based on IPCC (Intergovernmental Panel on Climate Change) administrative territorial scope that covers all anthropogenic emissions generated within an administrative boundary due to energy consumption (i.e. energy-related emissions from 17 fossil fuel types) and industrial production (i.e. process-related emissions from cement production). The inventories are constructed for 47 economic sectors consistent with the national economic accounting system. The data can be used as inputs to climate and integrated assessment models and for analysis of emission patterns of China and its regions.
Highlights
Background & SummaryChina’s economic development, energy consumption and associated emissions have entered a “new normal” stage[1] after a period of rapid development
Economic growth has slowed slightly in recent few years, while more attention has been paid to the optimization and upgrade of economic structures and drivers
After the United States withdrew from the Paris Agreement, China is playing an increasingly important role in global climate change mitigation and emission reduction and has set a series of reduction targets, such as peaking its emissions by 2030 ref. 4 and reducing emission intensity by 60%–65% compared with 2005 ref
Summary
China’s economic development, energy consumption and associated emissions have entered a “new normal” stage[1] after a period of rapid development. Some global emission datasets, such as Emissions Database for Global Atmospheric Research (EDGAR), Carbon Dioxide Information Analysis Center (CDIAC), British Petroleum (BP), and the U.S Energy Information Administration (EIA), cannot provide sufficiently accurate data estimates for China’s emissions as well. These datasets adopt different accounting scopes, methods, data sources, and parameters, leading. These global datasets only provide estimates for China’s overall emissions or at most for a few sectors and fuels They do not provide detailed emission inventories by sectors and fuels for subnational administrative units in China. All data have been uploaded to our open-access dataset: China Emission Accounts and Datasets www.ceads.net for free download
