Time series of (left column) annual CO2 emissions (Gt CO2 year−1) and (right column) monthly fossil CO2 emissions (Mt CO2 day−1) as estimated by GCP-GridFED. Uncertainties in CO2 emissions are treated as 5% for Annex I nations and global, following the GCB uncertainty assessment3. (Top row) Total global emissions are disaggregated to (other rows) the top 4 emission regions. Crosses mark input data directly from GCB-NAE3,33.
