« The World Bank published the Adjusted Net Savings (ANS) indicator for more than 200 countries in the Little Green Data Book, the World Bank’s annual compilation of environment data. Also known as genuine savings, ANS monitors whether depletion of natural capital, such as minerals or forests, is compensated for by investment in other assets, such as human capital or infrastructure. A positive ANS indicates that a country is adding to its overall wealth and that economic growth is on a sustainable path.
The Little Green Data Book 2013 is based on World Development Indicators 2013 and its online data base. It’s the result of close collaboration between the staff of the Development Data Group of the Development Economics Vice Presidency and the Agriculture and Environmental Services Department of the Sustainable Development Vice Presidency. »
