Regulation of environmental externalities like global warming from the burning of fossil fuels (e.g., coal and oil) is often done by capping both emission flows and stocks. For example, the European Union and states in the Northeastern United States have introduced caps on flows of carbon...

Nous analysons l’impact de deux politiques américaines sur la production et les échanges d’éthanol (biocarburants de première génération) et d’éthanol ligno-cellulosique (biocarburant de seconde génération) aux Etats-Unis et au Brésil ainsi que sur les émissions directes et...

In this paper, we show that the potential for endogenous technological change in alternative energy sources may alter the behaviour of resource-owning firms. When technological progress in an alternative energy source can occur through learning-by-doing, resource owners face competing incentives...

We study how the availability of an abatement technology affects the optimal use of polluting exhaustible resources, and optimal climate policies. We develop a Romer endogenous growth model in which the accumulated stock of greenhouse gas emissions harms social welfare. Since the abatement...

Carbon capture and sequestration (CCS) can help to mitigate the climate change transition. Usually, in models where the atmospheric carbon stock is constrained by an institutional stabilization cap and under constant average CCS cost, the use of CCS must be delayed up to the time at which the...

We study in this report a model of optimal Carbon Capture and Storage in which the reservoir of sequestered carbon is leaky, and pollution eventually is released into the atmosphere. We formulate the social planner problem as an optimal control program and we describe the optimal consumption...

Using a standard Hotelling model of resource exploitation, we determine the optimal consumption paths of three energy resources: dirty coal, which is depletable and carbon-emitting; clean coal, which is also depletable but carbon-free thanks to an abatement technology (CCS: Carbon Capture and...
