Furthermore, while structural change is not an end in itself, it has been shown to be a key driver of productivity growth. Finally, an improved measurement of sustainable productivity growth needs to account for the use of natural resources, including common pool resources such as fresh water and the emission of GHGs and other pollutants. The development of related indicators, including in the context of the OECD work on Green Growth, such as the Environmentally Adjusted Multifactor Productivity, is of key importance for this.
