This study presents a comprehensive dataset of China's CO₂ emissions from 1997 to 2015, compiled using the Intergovernmental Panel on Climate Change (IPCC) method. The dataset includes energy-related emissions from 17 fossil fuels across 47 sectors and process-related emissions from cement production. It provides nationally and provincially detailed emission inventories, along with energy data, to support further research and policy-making. The dataset is updated annually and includes both sectoral and reference approaches for estimating emissions. The sectoral approach calculates emissions based on fossil fuel consumption in specific sectors, while the reference approach uses energy supply data. The study highlights the significant increase in China's CO₂ emissions due to rapid economic growth and industrial expansion, with China accounting for 30% of global emissions. The dataset addresses discrepancies in previous estimates, which were often higher than official figures due to the use of IPCC default emission factors. The study also discusses uncertainties in the data, including variations in emission factors and fossil fuel consumption data, and provides a detailed analysis of these uncertainties. The dataset is available for download and includes detailed information on emissions by sector and fossil fuel type. The study emphasizes the importance of accurate emission data for effective climate policy and mitigation strategies.This study presents a comprehensive dataset of China's CO₂ emissions from 1997 to 2015, compiled using the Intergovernmental Panel on Climate Change (IPCC) method.
