“…D'un côté, les CGE néo-classiques qui supposent que la parfaite flexibilité des prix et des quantités assure à tout moment le plein emploi des facteurs de production. Parmi ces modèles, on peut citer (de manière non exhaustive) les modèles multi-pays de l'OCDE ENVLinkages (Chateau et al, 2014) GTAP (Center for Global Trade Analysis -GTAP, 2014), GEM-E3 (Capros et al, 2013), IMACLIM (Crassous et al, 2006 ;Sassi et al, 2010) ou le modèle multirégional RHOMOLO (Brandsma et al, 2015). D'autres modèles retiennent des hypothèses d'inspiration néo-keynésienne en introduisant des frictions : les ajustements des prix, du capital et du travail sont supposés lents du fait des rigidités et des coûts d'ajustement observés empiriquement.…”

Pour une large part, la macroéconomie environnementale se développe à l'écart des débats théoriques qui agitent les autres champs d'étude de la macroéconomie appliquée. En témoigne la faible représentation des questions environnementales dans les revues d'économie généralistes ou dans les manuels de macroéconomie avancée. Si l'environnement n'est jusqu'ici pas considéré comme un thème à même de faire progresser la connaissance en macroéconomie, il est depuis les années 1990 au moins un sujet important d'application des modèles macroéconomiques. En particulier, ces derniers sont utilisés pour analyser et quantifier les effets économiques de la transition vers un système de production et de consommation soutenable. Nous proposons d'apporter un éclairage sur l'état de l'art en macroéconomie environnementale appliquée. Plus particulièrement, nous nous attacherons à identifier les spécificités de cette thématique de recherche, qui expliquent les choix théoriques et empiriques qui y sont pratiqués.Mots clés : macroéconomie environnementale, modélisation macroéconomique, IAM, CGE.Il convient tout d'abord de souligner que dans la grande majorité des cas, la macroéconomie environnementale est avant tout une macroéconomie climatique. Les autres grandes thématiques de l'économie de l'environnement -limitation des externalités néga-tives, gestion des communs, exploitations des ressources renouvelables et non-renouvelables -relèvent d'autres branches de la discipline économique, telle que la microéconomie, l'économie

Rethinking the role of scenarios: Participatory scripting of low-carbon scenarios for France

2015

Abstract: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 its scripting process helps build consensus and a minimum level of agreement. We have scripted scenarios using a codevelopment method, involving about 40 stakeholders from the private and public sectors, and from the state: NGOs, consumer groups, trade unions, banks and local authorities. They selected policies they considered acceptable for achieving 75% greenhouse gases emission reductions in 2050. These policies were then integrated in the Imaclim-R France technicoeconomic simulation model, as part of a high or moderate acceptability scenario. In the first case emissions were cut by between 58% and 72% by 2050; in the second case by between 68% and 81%, depending on the energy price assumptions. All these measures benefited jobs and economic growth, swiftly and durably cutting household spending on energy services. This offers a solid basis for gaining acceptability for low carbon trajectories; the process constitutes also a framework for consolidating collective learning centring on the acceptability of climate policies.

“…IMACLIM-R (IMpact Assessment of CLIMate policiesRecursive version) is a dynamic recursive computable general equilibrium model specifically built to interface with bottom-up expertise on energy systems [Crassous et al, 2006]. The version that produced the scenarios commented upon in this paper projects the world economy every year up to 2050.…”

The impacts of long-term CO2 objectives on short-term transportation trends in the European Union

In 2001, the Sustainable Development Strategy was formulated by the European Union and, for the first time, a framework aimed at incorporating methods of sustainable development into European policy-making was adopted. In 2004, the European Union launched a review of the strategy and it has since been strengthened in a renewed strategy launched in 2006. Central to the renewed strategy is a commitment to cap global temperature rises to 2º C over pre-industrial levels by the end of this century. The EU has recently agreed on a target of reducing greenhouse gases by between 60 and 80 % by 2050 in order to achieve this goal. There has been little research on how the achievement of such a target would impact on European transportation trends. Given the new policy reality, this research develops projections simulating the impact of such a long-term target on road transportation growth in the European Union, and assesses how much of specific interim transport targets are implied by the presence of this long-term target. The projections are based on harmonised energy-economy simulations of the IMACLIM-R and POLES models. They cover the EU-27 disaggregated into 23 zones and track emissions of CO2 for a range of vehicles and technologies. The results indicate that while mobility trends are only marginally altered by the presence of a stringent climate change mitigation policy, energy efficiency in transport is improved significantly. However, we also find that the presence of an overarching climate change objective is not enough to guarantee meeting a number of interim transportation sub-targets.
