From the Treehugger.com website, here is a set of slides from James Hansen on economic policies to reduce greenhouse gas emissions. As the article's author notes "We need more influential academics like James Hansen to sound the alarm for a more robust alternative to the now conventional cap-and-trade approach."
This must especially be the case in New Zealand where we have emissions permit trading via our NZETS that is not even "cap-and-trade".
A blog written to explain that the New Zealand Emissions Trading Scheme will not effectively reduce greenhouse gas emissions.
