Production-based CO2 emission inventories
Cities contribute 85 % of the total CO2 emissions in China and thus are considered the key areas for implementing policies designed for climate change adaption and CO2 emission mitigation. CEADs developed a method for constructing a CO2 emissions inventory for Chinese cities in terms of the definition provided by the IPCC territorial (and sectoral) emission accounting approach. Please note this is an ongoing process, which involves data collection, compilation and verification. Here we present the first butch of inventories for 20 Chinese in the year 2010 and 18 cities in central China from the year 2000 to 2014. We will gradually upload all available inventories after we complete all validation processes. CEADs aim to advocate free, transparent, robust and can be validated dataset to non-academic users. Due to relatively low quality and availability of energy data and other information at the city level, we have our best effort to provide a most possibly robust inventory for any data we published online. We provide the full transparent process in compiling the inventory. You can find detailed methodology and data sources from the publication link below.
We welcome and call all interested parties to join us to improve the methodology in compiling city level inventories and construct a better and comprehensive dataset!

Consumption-based CO2 emission inventories
Most of China’s CO2 emissions are related to energy consumption in its cities. Thus, cities are critical for implementing China’s carbon emissions mitigation policies. In this study, we employ an input-output model to calculate consumption-based CO2 emissions for thirteen Chinese cities and find substantial differences between production- and consumption-based accounting in terms of both overall and per capita carbon emissions. Urban consumption not only leads to carbon emissions within a city’s own boundaries but also induces emissions in other regions via interregional trade. In megacities such as Shanghai, Beijing and Tianjin, approximately 70% of consumption-based emissions are imported from other regions. Annual per capita consumption-based emissions in the three megacities are 14, 12 and 10 tonnes of CO2 per person, respectively. Some medium-sized cities, such as Shenyang, Dalian and Ningbo, exhibit per capita emissions that resemble those in Tianjin. From the perspective of final use, capital formation is the largest contributor to consumption-based emissions at 32–65%. All thirteen cities are categorized by their trading patterns: five are production-based cities in which production-based emissions exceed consumption-based emissions, whereas eight are consumption-based cities, with the opposite emissions pattern. Moreover, production-based cities tend to become consumption-based as they undergo socioeconomic development.
