Analyzing CO2 emissions flows in the world economy using Global Emission Chains and Global Emission Trees
Because of the increasing international trade, monitoring tools are required that quantify and analyze CO2 emissions at a global level. This paper contributes to this literature by adopting a consumer-oriented approach and using two tools based on Multi-Regional Input-Output tables, i.e., the Global Emissions Chains (GECs) and the Global Emissions Trees (GETs). The GEC is proposed with an industry-level perspective so as to provide detailed information about the extent to which the final demand of an industry of a country drives indirect CO2 emissions by any industry of any other country.
