The Commission on the measurement of economic performance and social progress has been created at the beginning of 2008 on French government's initiative. Increasing concerns have been raised since a long time about the adequacy of current measures of economic performance, in particular those based on GDP figures. Moreover, there are broader concerns about the relevance of these figures as measures of societal well-being, as well as measures of economic, environmental, and social sustainability. Reflecting these concerns, President Sarkozy has decided to create this Commission, to look at the entire range of issues. Its aim is to identify the limits of GDP as an indicator of economic performance and social progress, to consider additional information required for the production of a more relevant picture, to discuss how to present this information in the most appropriate way, and to check the feasibility of measurement tools proposed by the Commission. Commission's work is not focused on France, nor on developed countries. The output of the Commission will be made public, providing a template for every interested country or group of countries."
