A global dataset of CO emissions and ancillary data related to emissions for 343 cities.

We present a global dataset of anthropogenic carbon dioxide (CO) emissions for 343 cities. The dataset builds upon data from CDP (187 cities, few in developing countries), the Bonn Center for Local Climate Action and Reporting (73 cities, mainly in developing countries), and data collected by Peking University (83 cities in China). The CDP data being self-reported by cities, we applied quality control procedures, documented the type of emissions and reporting method used, and made a correction to separate CO emissions from those of other greenhouse gases.
