																The remaining carbon budgets defined by the IPCC refer to cumulative anthropogenic CO₂ emissions, i.e. fossil and industrial CO₂ plus emissions from land-use change. For consistency with this definition, back-calculations from remaining budgets should use GCP’s fossil-plus-LUC series (or the nearly identical IGCC total excluding LULUCF). EDGAR’s LULUCF data are unsuitable because they include large management-related sinks and follow UNFCCC inventory accounting rather than the IPCC budget framework.
