The uncertainty surrounding both costs and benefits associated with global climate change mitigation creates enormous hurdles for scientists, stakeholders, and decisionmakers. A key issue is how policy choices balance uncertainty about costs and benefits. This balance arises in terms of the time...

We give theoretical, partial equilibrium comparisons of a tax with thresholds, tradable targets ('emissions trading' or ET), and non-tradable targets, as mechanisms to abate well-mixed ('global') emissions from many parties, under independent uncertainties in both future business-as-usual...

If one nation damages another, what are its obligations? This question can be approached and understood in diverse ways, but it is concretized in debates over the social cost of carbon, which is sometimes described as the linchpin of national climate policy. The social cost of carbon, meant to...

In its ideal form, arbitrariness review is an instrument for promoting “deliberative democracy” – a system that combines reason-giving with political accountability. Under arbitrariness review in its current form, courts tend to embrace the “hard look doctrine,” which has a procedural...

China had been singled out by Western politicians and media for dragging its feet on international climate negotiations at Copenhagen, the accusations previously always targeted on the U.S. To put such a criticism into perspective, this paper provides some reflections on China's stance and...

In what format and under what timeframe China would take on climate commitments is of significant relevance to China because it is facing great pressure both inside and outside international climate negotiations to exhibit greater ambition and is being confronted with the threats of trade...

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...

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...
