Embodied Emissions in Inputs and Outputs: A Value-Added Approach to National Emissions Accounting

We present a consumption-based greenhouse gas (GHG) accounting model for Canada, based on a multi regional input-output formulation. The outputs resulting from this model comprise a set of detailed input-output tables displaying trade in embodied emissions across regions and sectors (in contrast to the usual financial value input-output tables). After a complete exposition of our embodied GHG emission accounting model, we provide a brief analysis of production- and consumption-based GHG emission footprints and the related interregional trade in embodied emissions across Canadian provinces for 2004-2011. Our initial analysis is intended to present the model and illustrate general conclusions to highlight the utility of the resulting detailed GHG input-output tables as a resource for future research.
