World Bank – “Welcome to The Little Green Data Book 2015. For 15 years, we have been taking the pulse of development and the environment using more than 50 indicators for more than 200 countries. We strive to update and improve the indicators provided in The Little Green Data Book, so that it continues to be a relevant knowledge resource that aids policy makers in using environmental data more effectively to support priority-setting and improve development outcomes. This year the Sustainable Development Goals (SDGs) are expected to replace the Millennium Development Goals (MDGs), placing more emphasis on monitoring the environment. The in creasing importance of environmental statistics highlights the need to invest in improving environmental data.”
