Seven long-term prospective studies representing the energy trajectories consistent with a Factor Four, i.e. a 75% reduction of greenhouse gases emissions in 2050 in France have been identified. We analyze their methodology and the high dispersion of results. Then we discuss the role of...

This article considers the usefulness of low-carbon scenarios in public decision-making. They may be useful as a product-oriented trajectory. The scenarios on the agenda of the 2013 Energy Debate in France belong to this category. But a scenario may also be process-oriented, in the sense that...

The implementation of climate policies is often hindered by a lack of acceptability as well as the lack of long-term vision of stakeholders. Mitigation scenarios exercises allow the debate; however the scenario design process lacks transparency and stakeholders' (and citizens') involvement, which...

Cet article trouve son origine dans un double constat : le déficit d'acceptabilité des politiques climatiques d'une part et le déficit de crédibilité, de légitimité et d'appropriation des scénarios de réduction d'émission de gaz à effet de serre d'autre part. Pour répondre à ces...

Plusieurs exercices de prospective de long terme ont été élaborés pour définir les trajectoires énergétiques permettant de respecter le Facteur 4 en France. Sept ont été identifiés et sont analysés à la fois du point de vue méthodologique et des résultats. Une réflexion est alors...
