Consumption-based accounting (CBA) of emissions (also called carbon footprints) accounts for emissions associated with imported and exported goods. CBA reports the total emissions associated with final demand in each country.
Emissions physically occurring in a country are its territorial emissions. This is sometimes called production-based accounting (PBA). This is the standard reporting of GHG emissions as reported by CDIAC, IEA, the JRC EDGAR database, UNFCCC, and others.
CBA can be calculated using a global multi-region input-output (MRIO) model which traces global supply chains. This dataset uses the Eora MRIO model to calculate the CBA emissions for each country.
Emissions from fossil fuel combustion and cement production are reattributed to the countries where final demand induced the production associated with those emissions. Emissions from aviation and marine bunker fuels are not included in the CBA inventory, as no method has yet been developed to allocate emissions from bunker fuels to countries other than where the fuel is bunkered.
In this dataset, territorial emissions are taken from the PRIMAP emissions database, HISTCR scenario. Values are GgCO2eq KYOTO GHGs, excluding LULUFC. GDP data are from the World Bank. Population estimates are from the UN Population division (using the Medium Estimate projection). CBA results are from the Eora MRIO model (http://worldmrio.com) v199.82, years 1970-2017, by Daniel Moran, Keiichiro Kanemoto, and Arne Geschke.

While the above file shows the summary of a country's total footrint, the following files detail the countries (and sectors) in which that footprint originates. These files report flows of embodied CO2 from each origin/emitter country to each destination/consumer country. The first two files are are text-delimited files that can be opened as pivot tables in Excel. (Note that flows from country X to country X are domestic flows, i.e. emissions occuring in X that are allocated to final consumers in X.) The third and fourth files show the country and sector of origin of footprints in Full and Eora26 detail for 2017. Units are Gg CO2 (1 Gg = 1Kt). If you encounter any issues reading these data files please refer to the FAQ.
The following files document footprints embodied in trade at the sector level. The columns report total embodied GHG footprint due to consumption in each country, and the rows itemize the country-sector in which those embodied emissions were originally emitted. Please note that some of these results are available only with paid licenses and if a file is shown in grey it is not available with your current access.
We have linked the Eora global supply chain database to the EDGAR spatially explicit GHG emissions dataset, allowing us to better resolve within each origin country where GHG emissions are occuring upstream, for a given demand bundle.

Several MRIO models exist. There is variation in the CBA results across models, but this variation is generally considered acceptable. For more on intercomparison see:

Kander, A., Jiborn, M., D. Moran, Wiedmann, T. National Greenhouse Gas Accounting for Effective Climate Policy on International Trade. Nature Climate Change 10.1038/NCLIMATE2555
Identifies, and proposes a solution (technology-adjusted consumption-based accounting) for, a conceptual shortcoming of consumption-bsaed accounting by which individual countries could potentially game the system by taking actions that improve their carbon footprint more than their actual contribution to reducing global GHG emissions.

A comprehensive presentation of carbon footprint accounting (CBA) and the related Bilateral Embodied Emissions in Trade (BEET) concept, which measures embodied only bilateral trade, not further upstream - useful since most trade policy is set at bilateral trade borders, irrespective of additiaonl upstream or downstream countries.

Shows that shifting production and growing supply chains has mean that despite successful legislation in major economies, air pollution has grown globally. GHG emissions are following a similar trend.
