Graph | The environmental issue in the US | C. Billard, A. Creti and A. Mandel
In November 2020, the U.S. federal government formalized its withdrawal from the Paris Agreement, which aims to reduce global greenhouse gas emissions.
Following this, some American governors decide to take action against global warming through the adoption of environmental policies at the state level.
This graph by Anna Creti, Côme Billard and Antoine Mandel illustrates the diffusion of environmental policies between American states.
Côme Billard is in charge of European negotiations at the Ministry of Agriculture and Food Sovereignty. His doctoral research at the University Paris Dauphine-PSL (Climate economics Chair) focused on the economics of the environment, the economics of networks, and the dynamics of dissemination of environmental policies. His most recent work focuses on the climate economy and energy transition.
Anna Creti is professor at the University of Paris Dauphine, director of the Climate Economics Chair at Dauphine and of Economics of Gas Chair (Dauphine, Toulouse School of Economics, IFPEN, Ecole des Mines). She is a research fellow at the École Polytechnique and external affiliate with the Siebel Institute, Berkeley. Anna holds a PhD from the Toulouse School of Economics and a post-doc from the London School of Economics. She has extensively studied the competition and regulation of network utilities (telecommunications, baks, gas, electricity...), as well as the link between energy, climate and environmental regulation.
Antoine Mandel is professor at Paris School of Economics and at the University Paris 1 Panthéon-Sorbonne. He is also research fellow at the CNRS.
