A NEW SUT CONSOLIDATION METHOD TESTED BY A DECOMPOSITION OF VALUE ADDED AND CO₂ EMBODIED IN EU27 EXPORTS

This paper develops a method to consolidate national supply-use tables (SUTs) into a single supra-regional SUT. The method deals with mirror trade statistics problems, such as the different valuation of imports and exports, and it corrects for double-counting re-exports. The method is tested by means of a decomposition of value added and CO₂ emissions embodied in EU27 exports to third countries. When the national SUTs for the period 2000-2007 are used, neglecting intra-European Union spillover and feedback effects results in an underestimation of the embodied value added of 12-15%. Not consolidating the national tables properly leads to a further underestimation of 11-16%. With these underestimations removed, EU27 foreign exports still only explain around 11% of EU27 Gross Domestic Product, whereas they explain 17% of the EU27 CO₂ emissions. Hence, the income benefits of these exports are, in relative terms, considerably smaller than their CO₂ emission cost.
