The project has delivered an overview of MRIO (Multi regional input output) databases use potential to monitor the French final domestic demand carbon footprint. Different databases have been studied. Meanwhile, the contribution of the metal sector (mining, production and retreatment) to this French footprint has been studied. Lastly, a literature review on carbon leakages and carbon border adjustment mechanisms have been done. And the macro-economic effects (on GDP and employment) in the European Union and in France of the implementation of carbon border adjustment mechanisms were also presented.
