Timothé Beaufils

Doctoral Researcher

I am a Doctoral Researcher in the research group "Data-based climate decision". I focus on the interactions between climate change and supply chains. I use Multi-Regional Input Output Tables to analyze how international trade reshuffles responsibilities for Greenhouse Gas Emissions and other externalities. I develop new approaches to assess the implications of Border Carbon Adjustments on global cooperation against climate change.

I hold a Master Degree in Engineering from CentraleSupelec (France) with a major in Energy Networks and a Master of Environmental Economics from Université Paris-Saclay (France), with a major in prospective modelling applied to Energy, Environment and Transportation. My Master's thesis focused on applications of Multi-Regional Input-Output tables for decision-making and was the result of a collaboration between Pricewaterhouse Coppers France and PIK.

I started my doctoral research at PIK in May 2020.

My current research focuses on understanding how producers, consumers and intermediate can help reduce emissions along international supply chains. I developed the Throughflow Based Accounting (TBA) framework to quantify comprehensively the externalities caused by supply chains starting from, going through and ending in a given country. I have used this framework to evaluate the exposure of middle- and low-income countries to the European Carbon Border Adjustment Mechanism (CBAM). I am currently bringing together elements of Input-Output analysis, trade economics and game theory to explore the implications of CBAMs on global climate cooperation.

During my PhD, I have developed several methods and techniques to extend and analyze Multi-Regional Input-Output tables. I developed the Scenario-based Projection of the International trade Network (SPIN) method to generate Input-Output tables aligned with simplified long-term macro-economic scenarios and the Multi-Scale Mapping (MSM) to extrapolate Greenhouse Gases inventories to developing countries with a high sectoral resolution. I am currently developing a Python package to handle and exploit Multi-Regional Input-Output tables for externality accounting.
