The Global Carbon Project's fossil CO2 emissions dataset

The Global Carbon Project (GCP) has been publishing estimates of global and national fossil CO2 emissions since 2001. In the first instance these were simple re-publications of data from another source, but over subsequent years refinements have been made in response to feedback and identification of inaccuracies. In this article (PDF document) we describe the history of this process leading up to the methodology used in the 2024 release of the GCP's fossil CO2 dataset.

The fossil CO2 emissions dataset is included in both its standard, absolute form, and per capita, with associated metadata files in JSON format. A file indicating the source(s) of each data point is also provided.

This is a very minor update that is consistent with the GCB2024 release.
