ENSAE ALUMNMI - Webinar - 2% for 2nd

ENSAE Alumni invites you to take part in this interactive Webinar

with Gaël GIRAUD

An alumnus of ENSAE (1992), ENS Ulm and Ecole Polytechnique, Gaël Giraud is a French economist and Jesuit priest. A specialist in mathematical economics, formerly Chief Economist at the Agence Française de Développement and Director of Research at the CNRS, he is currently engaged as Director of the Environmental Justice Program at Georgetown University in Washington.

Gaël Giraud's research focuses on the interaction between political science, macroeconomics and the environment, and on political theology. It bears witness to a conviction: research in silo will not enable us to develop the socially and politically useful science needed to implement ecological reconstruction. We must therefore learn to engage in genuine dialogue between disciplines, without any one of them claiming to impose its episteme on the others.

Honorary President of the Institut Rousseau, Gaël Giraud took part in drawing up the "2% for 2° C" report on the costing of energy investments. C" report, which quantified the public and private investment needed to achieve carbon neutrality in France by 2050. One might have imagined that this costing had already been carried out: indeed, how can we think of national low-carbon strategies (SNBC) or multi-year energy programs (PPE) without simultaneously addressing the question of the budgetary and financial resources needed to achieve them? Surprisingly, such a "census" did not exist, despite scattered and incomplete attempts by public and private bodies to provide data.

The result? 2%. After months of work, the 23 experts mobilized conclude that we would need to mobilize a minimum of 2% of GDP per year to limit the rise in temperature by the end of this century to the limits set out in the Paris Agreement.
