Establishing green growth indicators does not imply starting from scratch. Many of the OECD indicators come from pre-existing work and as such are a grouping and reorganization of indicators already in use, but framed to assist in monitoring of green growth. In Germany, the OECD green growth indicators were tested, and it was found that 20 of 23 indicators could be produced using existing data (Statistisches Bundesamt, 2013). Many relevant indicators for green growth may already be found with sustainable development and national development goal indicators (see Case 2)
Millennium Development Goals (MDGs) and Sustainable Development Indicators (SDIs): Indicators are reported for almost all developing countries for such Millennium Development Goals as poverty reduction, school enrollment, and maternal health while many countries report also on a broader set of Sustainable Development Indicators such as to the United Nations Commission on Sustainable Development (UNCSD, 2014). These indicators cover important social, environmental, and economic aspects of development and as such can be framed in relation to green growth for example by selecting indicators related to green growth priorities or targets. These MDG and SDI indicators will serve as an important reference for green growth assessments.
National development goal indicators: Many countries, particularly developing countries, have national development goals and related indicators to monitor progress towards achieving these goals. In many cases, these national goals and indicators take into account national situations more effectively than universal or international goals and indicators, and as such are more relevant to the country. It is possible to frame national development indicators to allow for the monitoring and evaluation of green growth.
