Reconciling Development and Environmental Goals : Measuring the Impact of Policies Policy coherence is increasingly in the interest of OECD countries and developing countries alike given their growing economic social and environmental interdependence. This report presents scenarios showing numerical results of changes to individual policies as well as policy packages implemented simultaneously by OECD and developing countries. The results can be used to anticipate the outcomes of decisions and implement the appropriate set of policies. The scenarios also show how policy combinations could substantially improve both economic and environmental outcomes together confirming the need for policy coherence.
