"Here, we provide an economic appraisal to assess the sensitivity of CDR and conventional abatement to CO2 outgassing from the oceans. We develop a theoretical framework to study the impact of the ocean-to-atmosphere transfer on the optimal mitigation strategies under different regimes that control the relationship between CO2 outgassing and the amount of CDR."

"The potential of climate engineering to substitute or complement abatement of greenhouse gas emissions has been increasingly debated over the last years. The scientific assessment is driven to a large extent by assumptions regarding its effectiveness, costs, and impacts, all of which are profoundly uncertain. We investigate how this uncertainty about climate engineering affects the optimal abatement policy in the near term."

"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 response to the unpriced carbon externality only if it equals the marginal cost of carbon geoengineering; (ii) the introduction of solar geoengineering leads to higher emissions yet lower temperatures, and, thus, increased welfare; and (iii) solar geoengineering, in effect, is a public goods version of adaptation that also lowers temperatures."

"This article examines the implications for the EU’s energy system if an 80% reduction in CO₂ emissions is to be achieved by 2050 against 1990 levels, using the European TIMES Model (ETM-UCL) to project a least-cost pathway that meets this CO₂ constraint (‘Policy Success’), along with milestone targets for 2020. A Reference scenario (no CO₂ constraints post-2020) was analysed to allow for comparison."
