Book excerpt: Policies that promote green growth need to be founded on a good understanding of the determinants of green growth and need to be supported with appropriate indicators to monitor progress. This book is an update of the 2014 edition. It presents a selection of updated and new indicators that illustrate the progress that OECD and G20 countries have made since the 1990s. The OECD Green Growth Strategy supports countries in fostering economic growth and development while ensuring that natural assets continue to provide the resources and environmental services on which our well-being relies.
