This report is the result of collaborative work between the Stockholm Environment Institute and ISA, commissioned by Defra UK. It describes the development of a time series of input-output tables for the UK by using an automated data optimisation procedure that allows the construction of national input-output and environmental databases in greatest possible sector disaggregation, and that can be used for compiling multi-region environmental input-output models. Thus the work sets the basis for the routine calculation of carbon footprints for any country, enabling multi-regional analyses of environmental impacts associated with international trade flows, including the provision of a robust indicator for embedded emissions. The report has three parts: the Executive Summary, the main report, and a sensitivity and uncertainty calculation.
