Climate change mitigation requires to replace preexisting carbon-intensive capital with different types of cleaner capital. Coal power and inefficient thermal engines may be phased out by gas power and efficient thermal engines or by renewable power and electric vehicles. We derive the optimal...

The European Union Emissions Trading System (EU-ETS), presented as the ''flagship'' of European climate policy, is subject to many criticisms from different stakeholders. Criticisms include the insufficient carbon emissions reduction, the competitiveness losses and the induced carbon leakages,...

This article constitutes a new contribution to the analysis of overlapping instruments to cover the same emission sources. Using both an analytical and a numerical model, we show that when the risk that the CO2 price drops to zero and the political unavailability of a CO2 tax (at least in the...

In addition to the already present Climate and Energy package, the European Union (EU) plans to include a binding target to reduce energy consumption. We analyze the rationales the EU invokes to justify such an overlapping and develop a minimal common framework to study interactions arising from...

Decision makers facing abatement targets need to decide which abatement measures to implement, and in which order. Measure-explicit marginal abatement cost curves depict the cost and abating potential of available mitigation options. Using a simple intertemporal optimization model, we...

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...

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...

The effect of electrified vehicles (EVs) on greenhouse gas (GHG) emissions is subject to debate. Many studies assess EV's per-mile emissions based on the current carbon content of electricity. We use a simulation model to generate contrasting scenarios of the carbon content of European...

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...
