The Little Green Data Book 2010
The little green data book 2010 show wide disparities across regions. For example, urban air pollution declined in most countries between 2000 and 2006 (the most recent year for which data is available), with the greatest progress in low-income and lower middle-income countries. But concentration levels are still nearly three times higher in these countries than in high-income countries. The book also estimates adjusted net savings, which measures the annual changes in a country's total wealth. The literature shows that a positive adjusted net savings rate is a necessary condition although not a sufficient one for sustained growth. Unfortunately, many economies appear to be failing this practical test. The book is a knowledge resource that aids policymakers in using environmental data more effectively to support priority-setting and improved development outcomes.
