A new post on the U.S. Law’s environmental law blog site reports that Australia’s Labor government has dropped its Carbon Pollution Reduction Scheme until at least the next election, or possibly the one after that. It’s the second discouraging legislative setback this week, with the Kerry-Graham-Lieberman bill in the United States imperiled by Senate Graham’s withdrawal from sponsorship of the bill over his pique about the Democrats’ decision to take up immigration legislation first (though it looks like the Democrats may cave on this). These developments could lead to a good discussion with students about whether the pledges made under the Copenhagen Accord are chimerical given these developments. What is Plan B in Australia and the U.S.? What is the potential impact on the ever-fading prospects for a breakthrough at COP16 in Cancun?
