Nontechnical SummaryNational sustainability indices provide a one-dimensional metric to valuate country-specific information on the three holistic dimensions of sustainable development: economic, environmental, and social conditions. At the policy level, they suggest an unambiguous yardstick against which a country's development can be measured and even a cross-country comparison can be performed. However it remains questionable whether we can meaningfully speak from unambiguousness in the holistic subject of sustainability development.This paper reviews the consistency and meaningfulness of eleven sustainability indices that We find that -although the sustainability indices are imputed to be concise and transparentthey fail to meet fundamental scientific requirements with respect to the three central steps of indices formation: normalization, weighting, and aggregation. Normalization and weighting of indicators -which in general are associated with subjective judgments -reveal a high degree of arbitrariness without mentioning or systematically assessing critical assumptions.As to aggregation, there are scientific rules which could guarantee consistency and meaningfulness of composite indices. Yet, these rules are often not taken into account. As a consequence, sustainability indices currently employed in policy practice are doomed to be useless if not misleading with respect to concrete policy advice. Abstract. Sustainability indices for countries provide a one-dimensional metric to valuate country-specific information on the three dimensions of sustainable development: economic, environmental, and social conditions. At the policy level, they suggest an unambiguous yardstick against which a country's development can be measured and even a cross-country comparison can be performed. This paper reviews the explanatory power of various sustainability indices applied in policy practice. We show that these indices fail to fulfill fundamental scientific requirements making them rather useless if not misleading with respect to policy advice.
