Constructing an environmentally-extended multi-regional input-output table using the GTAP database


Abstract

The use of Multi-Regional Input-Output Analysis (MRIOA) for understanding global environmental problems is growing rapidly. Renewed interest in MRIOA has led to several large research projects focused on constructing detailed and accurate MRIOTs. However, very few researchers have made use of the already available and regularly updated database produced by the Global Trade Analysis Project (GTAP).

We demonstrate and discuss how the GTAP database can be converted into an MRIOT without the need for additional balancing. An illustrative example uses the GTAP-MRIO to reallocate carbon dioxide emissions from producing to consuming countries. We suggest that an MRIOT that treats international transport exogenously is adequate until more reliable data on international transport margins and emissions are available.

To focus resources and refine methods, a concerted research effort is needed to compare the results of the GTAP-MRIO model with the new MRIO datasets under development.

A synthesis of carbon in international trade

In this comprehensive and up-to-date overview of the analysis of carbon embodied in international trade, Glen Peters and colleagues bring together treatments of some of the key issues, and introduce important new analyses. Learn more »

Approximating MRIO

Because of the cost and perceived difficulty of using full multi-regional input–output (MRIO) models to calculate emissions embodied in international trade, many researchers use simpler approaches, making key assumptions and approximations. In this study, Robbie Andrew and colleagues investigate the effects of these approximations and provide advice on their use. Learn more »

Sharing responsibility

The two prevalent approaches to allocating responsibility for greenhouse gas emissions – production and consumption perspectives – push responsibility to either end of the supply chain. In this study, Robbie Andrew and Vicky Forgie present the first national-level application of the shared responsibility perspective. Learn more »
