Timothé Beaufils

Doctoral Researcher

I am a Doctoral Researcher in the research group "Data-based climate decision". I use Multi-Regional Input Output Tables to explore how international trade can help us mitigate climate change and its impacts. I develop innovative approaches to analyze the impact of local climate policies on foreign countries.

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. My Master thesis focused on applications of 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.

I develop 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.

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 framework to quantify comprehensively the externalities caused by supply chains starting from, going through and ending in a given country. I am now using these approaches to evaluate whether unilateral trade policies such as Carbon Border Adjustment Mechanisms could incite foreign countries to implement more ambitious climate policies.
