The Global Carbon Project's fossil CO2 emissions dataset

  • 1. CICERO Center for International Climate Research

Description

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 2026 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 the initial release of the 2026 dataset.
