International trade, pollution, and economic structure: evidence on CO2 emissions for the North and the South

This study investigates the mechanics of international trade and CO2 emissions in two blocs of countries (North' and South') by analyzing data from the World Input-Output Database. We adapt the Miyazawa technique to estimate the linkages between international trade and the environment at a global scale. Therefore, this study is in line with the idea of highlighting the role of feedback effects as well as the nature and extent of extra-regional influences on an economy in response to an additional stimulus. This is a contribution that, to our best knowledge, has not yet appeared in the literature. Our results suggest that both the North and the South have become less pollution-intensive (technique effect) over the years. Interestingly and in contrast to much of the literature, we also find support to the hypothesis that the South has specialized in relatively more pollution-intensive activities (composition effect).
