This paper describes how, over the past two decades, the usefulness of U.S. tactical nuclear weapons that are forward-deployed in Europe has gradually declined, and it explains the logic behind their decreased importance.

This article considers whether coal must depart or whether it may still dominate power production during the 21st century, in view of the challenges implied by regional pollution reduction and global warming mitigation.

The adoption of carbon dioxide capture and storage (CCS) technologies is increasingly considered a potentially significant contributor to the energy infrastructure changes required to stabilize atmospheric carbon dioxide (CO2) concentrations for the mitigation of climate change. 

The Economics of Reprocessing Versus Direct Disposal of Spent Nuclear Fuel

How large is the social cost penalty if one makes the wrong choice because of uncertainties in the estimates of the costs and benefits of environmental policy measures? For discrete choices there is no general rule other than the recommendation to always carefully compare costs and benefits when introducing policies for environmental protection.

This paper gives an overview of uncertainties related to endogenous learning as observed in integrated assessment models (IAMs) of global warming, both for bottom-up and top-down climate-energy-economic models.

This paper analyses the optimal timing and macro-economic costs of carbon emission reductions that mitigate the global average atmospheric temperature increase.

What is the impact of carbon taxes on emission levels, when niche markets exist for new carbon-free technologies, and when these technologies experience "learning-by-doing" effects?

The problem of global climate change will be solved by meeting stringent, long-term policy targets that are much more ambitious than the short-term, greenhouse gas emissions reductions that some countries currently attempt to reach.
