We couple a spatially homogeneous energy balance climate model with an economic growth model which incorporates two potential policies against climate change: mitigation, which is the traditional policy, and geoengineering. We analyze the optimal policy mix of geoengineering and mitigation in...

We study a dynamic game of climate policy design in terms of emissions and solar radiation management (SRM) involving two heterogeneous regions or countries. Countries emit greenhouse gasses (GHGs), and can block incoming radiation by unilateral SRM activities, thus reducing global temperature....

Having risen from relative obscurity as few as ten years ago, climate change now looms large among environmental policy issues. Its scope is global; the potential environmental and economic impacts are ubiquitous; the potential restrictions on human choices touch the most basic goals of people...

Climate negotiations have largely failed, so a change of course is required. This requires that a sizable group of experts recommend a small, clear set of policy guideposts that lead to a more cooperative treaty. This papers proposes a set of three guideposts and derives them from an analysis of...

This article examines whether a greenhouse gas emissions trading scheme has the potential to bring parties into conflict with the WTO provisions in dealing with the initial allocation of permits, non-compliance with emissions targets, emissions trading system enlargement, and trade measures...

There are increasing signals that countries that negotiate on GHG emission control are unlikely to sign and ratify a single climate protocol, even though almost all countries have subscribed the UNFCCC convention that sets the framework of international climate cooperation. In addition to the US...

As GHG emissions did not decline as anticipated early of the 1990ties Carbon Capture and Storage (CCS) recently gained more and more attention as a climate change mitigation option. However, CO2 suppressed in geological reservoirs is likely to lead to future releases of the CO2 stored. This...

Regardless of whether or not the Kyoto Protocol enters into force, the EU may decide to set itself a long-term greenhouse gas emission target and thus to continue its leadership role in international climate policy. As for the first commitment period of the Kyoto Protocol, the EU may decide on a...

The textbook economists' model of a tradable permit system cannot usually be applied perfectly at either the domestic or international scale because of the difficulty and/or expense of defining allocations to and monitoring emissions of some groups, as well as for political reasons. It may be...

Afforestation and reforestation (AR) projects in the Clean Development Mechanism are able to create emission permits that can be accounted against the industrialized countries' commitments for limiting their greenhouse gas emissions, as agreed under the Kyoto Protocol. The discussion of how to...
