The Amazon Rainforest is a global public good. As such, and given that 15 percent of the original Amazon forest area has already been lost, households worldwide might be willing to pay to reduce or avoid additional losses. A full elicitation of global preferences for valuing preservation of the...

The Amazon rainforest, the world's largest and most biodiverse, represents a global public good of which 15 percent has already been lost. The worldwide value of preserving the remaining forest is today unknown. A"Delphi"exercise was conducted involving more than 200 environmental valuation...

The international aviation and maritime sectors today enjoy relatively favorable tax treatment, as their fuels are not taxed and the sectors are not subject to any value-added tax or turnover tax. Nor are these fuel uses subject to any global measures to reduce their associated CO2 emissions,...

This paper provides a primer on the fiscal implications of climate change, in particular the policies for responding to it. Many of the complicated challenges that arise in limiting climate change (through greenhouse gas emissions mitigation), and in dealing with the effects that remain (through...

This paper provides a first analysis of optimal offset policies by a"policy bloc"of fossil fuel importers implementing a climate policy, facing a (non-policy) fringe of other importers, and a bloc of fuel exporters. The policy bloc uses either a carbon tax or a cap-and-trade scheme, jointly with...

Energy-intensive infrastructure may tie up fossil energy use and carbon emissions for a long time after investments, making the structure of such investments crucial for society. Much or most of the resulting carbon emissions can often be eliminated later, through a costly retrofit. This paper...

This paper surveys the current state of knowledge concerning the value of the Amazon rainforest, including a survey of work to date to quantify changes in economic values when the rainforest cover changes. The focus is on local and regional impacts of forest loss or protection, including both...

This paper studies interactions between a"policy bloc's"emissions quota market and an offset market where emissions offsets can be purchased from a non-policy"fringe"of countries (such as for the Clean Development Mechanism under the Kyoto Protocol). Policy-bloc firms enjoy free quota...

This paper develops a global model of climate policy, focusing on the choice between tax and cap-and-trade solutions. The analysis assumes that the world can be split into two regions, with two fuels that both lead to carbon emissions. Region A consumes all fuels, and is responsible for defining...

This paper uses some simple conceptual models to draw out various implications of infrastructure investments with long lifetimes for the ability of societies to reduce their future greenhouse gas emissions. A broad range of such investments, related both to energy supply and demand systems, may...
