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 EDGAR emissions database. Population and GDP data are from the World Bank. CBA results are from the Eora MRIO model (http://worldmrio.com) v199.82, years 1970-2015, 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 in which that footprint originates. These files report flows of embodied CO2 from each origin/emitter country to each destination/consumer country. These are text-delimited files that can be opened as pivot tables in Excel. Flows from country X to country X are domestic flows, i.e. emissions occuring in X that are allocated to final consumers in X.
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:

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.
