The Conference of the Parties (COP) has proven a valuable outlet to advance the climate agenda. The combination of high media coverage, extremely high expectations set by influential environmentalists, and unanimity rules has, however, started to limit its effectiveness. Technical issues can...

We model countries' choice of greenhouse gas (GHG) emissions as a dynamic game. Emissions generate immediate benefits to the emitting country but also increase atmospheric GHG concentrations that negatively affect present and future welfare of all countries. Because there are no international...

The European Union (EU) is implementing a Carbon Border Adjustment Mechanism (CBAM) at its borders, which will require exporters of basic materials to surrender emission permits when exporting to the EU market. Since it makes foreign producers compete under a carbon price, the EU CBAM may...

In absence of joint global climate action, several jurisdictions unilaterally restrict their domestic demand for fossil fuels. Another policy option for fossil fuel producing countries, not much explored, is to reduce own supply of fossil fuels. We explore analytically and numerically how...

Why have policies aimed at reducing the demand for carbon not succeeded in slowing down global carbon extraction and CO2 emissions, and why have carbon prices failed to increase over the last three decades? This comment argues that this is because of the Green Paradox, i.e. - (the anticipation...

According to the Framework Convention on Climate Change, global collective action is needed to stabilize "greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous [our emphasis] anthropogenic interference with the climate system." The Framework Convention thus...

In this paper we test empirically with the Nordhaus and Yang (1996) RICE model the core property of the transfer scheme adv ocated by Germain, Toint and Tulkens (1997). This scheme is designed to sustain full cooperation in a voluntary international environmental agreement by making all...
