Long-Term Mitigation May Cost 0.1% of Average Global Annual GDP Growth - OECD [viewed]
18 September 2009: A new book titled The Economics of Climate Change Mitigation: Policies and Options for Global Action Beyond 2012, launched by the Organisation of Economic Co-operation and Development (OECD), concludes that a full-fledged global carbon market would cost just one-tenth of a percent of average world annual GDP growth between 2012 and 2050 to achieve moderately ambitious climate targets. Put differently, this would mean a 4% reduction in GDP in 2050 compared to a scenario where no policy action is taken. Over the same period, world GDP growth is projected to grow by more than 250%.
