The Johannesburg World Summit on Sustainable Development called on states to "take immediate steps to make progress in the formulation and elaboration of national strategies for sustainable development and begin their implementation by 2005". In the preparations for
the Johannesburg conference and subsequently, increasing attention has been paid to evaluating National Sustainable Development Strategies (NSDS) to ensure that they are effective in meeting national sustainable development goals and related international commitments.
Several approaches have been used for this (OECD, 2005; UNDESA, 2005). This paper reviews experience with these evaluation approaches, with the aim of identifying good practice and presenting recommendations for potential improvement.
