Joseph E. Stiglitz has international carbon taxing including enforcement with trade sanctions as advocated here and taught us about the WTO precedent for using such sanctions. In January 2010 he published and op-ed advocating "a commitment by each country to raise the price of emissions (whether through a carbon tax or emissions caps) to an agreed level." This aligns him with Cooper. William D. Nordhaus has long advocated harmonized global carbon taxes. Scott Barret's critique of the Kyoto treaty is very similar to the one presented here and has substantially influenced the way we view the contribution of global carbon pricing. See his two books: Why Cooperate?: The Incentive to Supply Global Public Goods (2007), and Environment and Statecraft: The Strategy of Environmental Treaty-Making (2006). See also a number of quotes from those with similar critiques of the Kyoto approach (quotes). |
