CO_2 emissions embodied in international trade: evidence for Spain

摘要

The objective of this paper is to analyse the sectoral impacts that Spanish international trade relations have on present levels of atmospheric pollution using an input-output model. We try to evaluate the exports and imports of the Spanish economy in terms of the direct and indirect CO_2 emissions (CO_2 embodied) generated in Spain and abroad. The results show a slightly exporting behaviour in the Spanish economy which, nevertheless, hides important pollution interchanges. Moreover, the sectors transport material, mining and energy, non-metallic industries, chemical and metals are the most relevant CO_2 exporters and other services, construction, transport material and food the biggest CO_2 importers, and those whose final demands also embody more than 70% of the CO_2 emissions.
