This paper uses a Ramsey model with two types of capital to analyze the optimal transition to clean capital when polluting investment is irreversible. The cost of climate mitigation decomposes as a technical cost of using clean instead of polluting capital and a transition cost from the...

The optimal timing, sectoral distribution, and cost of greenhouse gas emission reductions is different when abatement is obtained though abatement expenditures chosen along an abatement cost curve, or through investment in low-carbon capital. In the latter framework, optimal investment costs...

Green industrial policies can be defined as industrial policies with an environmental goal -- or more precisely, as sector-targeted policies that affect the economic production structure with the aim of generating environmental benefits. This paper provides a framework to assess their...

Decision makers facing abatement targets need to decide which abatement measures to implement, and in which order. This paper investigates the ability of marginal abatement cost (MAC) curves to inform this decision, reanalysing a MAC curve developed by the World Bank on Brazil. Misinterpreting...

This paper compares the temporal profile of efforts to curb greenhouse gas emissions induced by two mitigation strategies: a regulation of all emissions with a carbon price and a regulation of emissions embedded in new capital only, using capital-based instruments such as investment regulation,...

Despite the inextricable link between oil scarcity and climate change, the interplay between these two issues is paradoxically an underworked area. This article uses a global energy-economy model to address the link between future oil supply and climate change and assesses in a common framework...

This paper investigates the optimal implementation schedule of the measures listed in a Marginal Abatement Cost Curves (MACC). Costs and abating potentials of each measure, provided by a MACC, are completed with a maximum implementation speed. We find that, when coping with a carbon budget, it...

La pertinence des véhicules électrifiés (VE) pour diminuer les émissions de gaz à effet de serre (GES) est sujette à débat. De nombreuses études fondent le calcul des émissions kilométriques des VE sur le contenu carbone de l'électricité contemporaine. Nous proposons une évaluation...

Climate mitigation is largely done through investments in low-carbon capital that will have long-lasting effects on emissions. In a model that represents explicitly low-carbon capital accumulation, optimal marginal investment costs differ across sectors. They are equal to the value of avoided...

Les politiques de sécurité énergétique et les politiques climatiques sont souvent considérées comme les deux faces d'une même pièce, leurs objectifs étant identiques, ou tout au moins complémentaires. Pourtant, si ces politiques partagent indéniablement une cause commune, la demande...
