11 The cost of action is still affordable for now The average GDP growth rate would slow by 0.2 percentage point between 2010 and 2050, from 3.5% to 3.3% in a context of quadrupling of world GDP. Benefits of action are not included in GDP projection Index 2010= Baseline 450 ppm core scenario GDP GHG emissions GDP -5.5% 100 GHG emissions -69.5% Source: OECD (2012), OECD Environmental Outlook to 2050, Baseline projection using ENV-Linkages model 11
