摘要: Environmentally extended input output (EE IO) analysis is increasingly used to assess the carbon footprint of final consumption. Official EE IO data are, however, at best available for single countries or regions such as EU27. This causes problems in assessing pollution embodied imported products. The popular “domestic technology assumption (DTA)” leads errors. Improved approaches based on Life Cycle Inventory data, Multiregional tables, etc. rely unofficial research and modeling, making them difficult implement by statistical offices. DTA can lead errors three main reasons: exporting have higher impact intensities; may use more intermediate inputs same output; sell products lower/other prices than those produced domestically. last factor relevant sustainable consumption policies importing countries, whereas first factors are mainly a matter production eco-efficient. ...
