This paper introduces geoengineering into an optimal control model of climate change economics. Together with mitigation and adaptation, carbon and solar geoengineering span the universe of possible climate policies. Their wildly different characteristics have important implications for climate...

This paper introduces geoengineering into an optimal control model of climate change economics. Together with mitigation and adaptation, carbon and solar geoengineering span the universe of possible climate policies. We show in the context of our model that: (i) a carbon tax is the optimal...

Ce texte porte sur la question de la réversibilité à long terme des émissions de CO2. Il donne un exemple de technologies de capture directe à partir de l'air, qui permet de borner le coût marginal de réduction du CO2 dans toute l'économie. Il exploré les aspects thermodynamiques de la...

Les combustibles fossiles peuvent être utilisés avec peu d'émissions en capturant le dioxyde de carbone et en le stockant dans des structures géologiques. Cependant, une fraction du carbone stocké pourrait fuir vers l'atmosphère, ce qui limiterait l'utilité de cette technologie. Afin...

Debates surrounding the greenhouse gas (GHG) emissions from land use of biofuels production have created a need to quantify the relative land use GHG intensity of fossil fuels. When contrasting land use GHG intensity of fossil fuel and biofuel production, it is the energy yield that greatly...
