RT Journal Article SR 00 ID 10.3917/reco.741.0051 A1 Crampes, Claude A1 Léautier, Thomas-Olivier T1 Les Certificats d'Economie d'Energie entre économie et politique JF Revue Économique YR 2023 FD 2023 VO vol. 74 IS n° 1 SP 51 OP 80 K1 Economies d’énergie K1 Certificats blancs K1 Micro-politiques K1 Mécanismes incitatifs AB To encourage building renovations and the replacement of old energy-consuming equipment, some governments have introduced a system of white certificates requiring large producers and distributors of natural gas, electricity and fuel to prove that they have financed energy-saving operations. The system is proving to be much less efficient than expected because energy saving works are "credence goods", which means that their quality can be correctly measured neither before nor after their achievement. Because of this informational bias, white certificates encourage economically inefficient works. Despite this, they are favored by the public authorities because they belong to the panoply of nonpunitive, non-fiscal, decentralized and local job-creating micro-policies.
