We derive the optimal contributions to global climate policy when countries differ with respect to income level and pollution intensity. Countries' growth rates are determined endogenously, and abatement efficiency is improved by technical progress. We show that country heterogeneity has a...

China’s unilateral pledge to cut its carbon intensity by 40-45 percent by 2020 relative to its 2005 levels raises both the stringency issue, and given that China’s pledge is in the form of carbon intensity, reliability issues concerning China’s statistics on energy and GDP. Moreover, as...

This article analyzes the international emissions trading regime at the heart of the world's effort to address global warming as a means of exploring broader international governance issues. The trading regime seeks to marry two models of global governance, market liberalism, which embraces...

This article discusses how different climate policy instruments such as CO2 taxes and renewable energy subsidies affect the profitability of fossil fuel production, given that a fixed global climate target shall be achieved in the long term. Within an intertemporal framework, the model analyses...

Climate financing and compensation have emerged as key themes in the international climate mitigation debate. According to one argument in support of compensation, advanced economies (AEs) have used up much of the atmosphere’s absorptive capacity, thus causing global warming and blocking a...

Land use and land use change are determined as much by economic and institutional drivers as they depend on bio-physical conditions. Future pathways of socio-economic and environmental systems can only be assessed with scenarios which describe possible future paths of development. For this...

In this study, cost-effective technological options to stabilize CO2 concentrations at 550, 500, and 450 ppmv are evaluated using a world energy systems model of linear programming with a high regional resolution. This model treats technological change endogenously for wind power, photovoltaics,...

At present, oil markets appear to be behaving in a fashion similar to that in the late 1970s and early 1980s when oil prices rose sharply over an extended period. Furthermore, like at that time, analysts are split on whether such increases will persist or reverse, and if so by how much. The...
