What should be the West's top priority for climate-change policy? This article is a revised and updated version of my talk to the Potsdam Global Sustainability Symposium (which drafted the Potsdam Declaration presented to the 2007 UN Climate Change Conference in Bali).

Vehicle taxation based on CO2 emissions is increasingly being adopted worldwide in order to shift consumer purchases to low-carbon cars, yet little is known about the effectiveness and overall economic impact of these schemes. We focus on feebate schemes, which impose a fee on high-carbon...

Climate change mitigation programs classify two types of carbon offsets: Additional and non-additional. Additional offsets are offsets that correspond to actual reductions in emissions. In contrast, non-additional offsets are offsets that do not correspond to emissions reductions. These offsets...

This paper examines future energy and emissions scenarios in China generated by the Integrated Assessment Model WITCH. A Business-as-Usual scenario is compared with five scenarios in which Greenhouse Gases emissions are taxed, at different levels. The elasticity of China’s emissions is...

There is a large consensus among international institutions and national governments to favor urban-containment policies - the compact city - as a way to improve the ecological performance of the urban system. This approach overlooks a fundamental fact: what matters for the ecological outcome of...

We design a global refunding scheme as a new international approach to address climate change. A global refunding system allows each country to set its carbon emission tax, while aggregate tax revenues are partially refunded to member countries in proportion to the relative emission reductions...

We propose a blueprint for an international emission permit market such as the EU trading scheme. Each country decides on the amount of permits it wants to offer. A fraction of these permits is grandfathered, the remainder is auctioned. Revenues from the auction are collected in a global fund...

We suggest a development-compatible refunding system designed to mitigate climate change. Industrial countries pay an initial fee into a global fund. Each country chooses its national carbon tax. Part of the global fund is refunded to developing and industrial countries, in proportion to the...

International markets for tradable emission permits (TEP) co-exist with national energy taxation. A firm trading emission permits in the international market also pays energy taxes in its host country, thus creating an interaction between the international TEP-market and national energy taxes....

This paper studies fiscal federalism when regions differ in voters’ ability to monitor public officials. We develop a model of political agency in which rent-seeking politicians provide public goods to win support from heterogeneously informed voters. In equilibrium, voter information...
