Working Paper 10-17 - Belgium’s Carbon Footprint - Calculations based on a national accounts consistent global multi-regional input-output table

The traditional attribution of responsibility for greenhouse gas (GHG) emissions to producing countries may be distorted by international trade flows as importing emission-intensive commodities contributes to reducing a country's production-based emissions. This has motivated the calculation of carbon footprints that measure the amount of domestic and foreign GHG emissions (directly and indirectly) embodied in commodities intended for final consumption by a country's residents. In thisworking paper, we present carbon footprint estimations for Belgium based on global multi-regional input-output (MRIO) tables that have been made consistent with detailed Belgian national accounts. According to our calculations, Belgium's carbon footprint is substantially higher than its productionbased emissions, which means that Belgium is a net importer of GHG emissions. Moreover, our results show that consistency with detailed national accounts does matter for MRIO-based carbon footprint calculations, in particular for a small open economy like Belgium.
