Calcul économique et valeur carbone " conference, November 21 

The introduction of global climate policies has led to the emergence of prices for reducing emissions of the main greenhouse gas, carbon dioxide. These prices can be explicit - like those appearing on emissions permit markets - or they can be implicit - in the sense that they can be deduced from the choices made. Today, they are highly heterogeneous, both between countries and between sectors within a single country.
Should we now recommend displaying a uniform carbon value, or differentiated values, to guide choices and in particular public choices in France ?

This question echoes the work undertaken by the Energy Commission set up by the public authorities last June.
