Global Carbon Budget
Data

Data Sources

The annual update of the Global Carbon Budget is possible thanks to many institutions, observation networks and modeling groups around the world.

All datasets and modeling output to complete the Global Carbon Budget 2017 are described in detail in Le Quéré et al. (2017) https://doi.org/10.5194/essd-2017-123.

All datasets contributing to the Global Carbon Budget 2017 have been integrated in to two Excel files, global budget and national emissions. They are archived in ICOS: https://doi.org/10.18160/GCP-2017. Previous years are stored at CDIAC and in The Global Carbon Budget Archive. The data is also available in CSV form courtesy of Robert Gieseke.

Data Sources and Terms of Use

The use of data is conditional on citing the original data sources. Full details on how to cite the data are given at the top of each page. For research projects, if the data are essential to the work, or if an important result or conclusion depends on the data, co-authorship may need to be considered. The Global Carbon Project facilitates access to data to encourage its use and promote a good understanding of the carbon cycle. Respecting original data sources is key to help secure the support of data providers to enhance, maintain and update valuable data. For further details, check Governance, Appendix A: Fair use policy for model data.
