Sectoral input-output models and environmental policy – a state of play

The guiding question of this presentation is : how can we obtain a structured understanding of the environmental pressures that come along with the functioning of our current economic structure, in order to design viable pathways that help to mitigate environmental pressures? 

To solve this question, multiple methodological frameworks are at our disposal (integrated assessment models or IAMs, energy system models, system dynamics or dynamical systems, life cycle analysis or LCA, sectoral input-output models, etc..). This presentation will focus specifically on input-output models, as they are closely linked to the existing institutional set-up in terms of data gathering and are able to start from a detailed sectoral breakdown of our current economic structure (System of National Accounts SNA and System of Environmental-Economic Accounting SEEA).
First, a basic overview of the structure and functioning of different types of input-output models will be discussed (monetary, hybrid or physical; static or dynamic). Secondly, the main databases that are currently at our disposal will be highlighted: what kind of data is available and what type of data could be interesting to compile in the future? Thirdly, we will explore some applications of the methodological framework in historical and contemporary environmental policy.
For further exploration, a textual and visual overview of key authors and methodological schools of thought (in particular input-output models) can be found on pdf pages 19-22 and 245 in
