In the absence of significant greenhouse gas (GHG) mitigation, many analysts project that atmospheric concentrations of species identified for control in the Kyoto protocol could exceed 1000 ppm (carbon-dioxide-equivalent) by 2100 from the current levels of about 435 ppm. This could lead to...

Because of the global commons nature of climate change, international cooperation among nations will likely be necessary for meaningful action at the global level. At the same time, it will inevitably be up to the actions of sovereign nations to put in place policies that bring about meaningful...

Policies aimed at reducing emissions from fossil fuels may increase climate damages. This 'Green Paradox' emerges if resource owners increase near-term extraction in fear of stricter future policy measures. Hans-Werner Sinn (2008) showed that the paradox occurs when increasing resource taxes are...

China, from its own perspective cannot afford to, and from an international perspective, is not allowed to continue on the conventional path of encouraging economic growth at the expense of the environment. The country needs to transform its economy to effectively address concern about a range...

Emissions of greenhouse gases linked with global climate change are affected by diverse aspects of economic activity, including individual consumption, business investment, and government spending. An effective climate policy will have to modify the decision calculus for these activities in the...

China has realized that for its own sake and from the international community's perspective, it cannot afford to continue along the conventional path of encouraging economic growth at the expense of the environment. Accordingly, the country has placed ecological goals at the same level of...

The mismatch between actions to combat climate change, which are based on voluntary national initiatives of limited effort, and the recognition of the importance of global warming is growing. Climate engineering via solar radiation management has been proposed as a possible complement to...

The outcome of the December 2011 United Nations climate negotiations in Durban, South Africa, provides an important new opportunity to move toward an international climate policy architecture that is capable of delivering broad international participation and significant global CO2 emissions...

There is growing impetus for a domestic U.S. climate policy that can provide meaningful reductions in emissions of CO2 and other greenhouse gases. In this article, I propose and analyze a scientifically sound, economically rational, and politically feasible approach for the United States to...

There is growing impetus for a domestic U.S. climate policy that can provide meaningful reductions in emissions of CO2 and other greenhouse gases. I describe and analyze an up- stream, economy-wide CO2 cap-and-trade system which implements a gradual trajectory of emissions reductions (with...
