Abstract In this paper a cluster analysis is applied to an input-state-output indicator framework that represents the interconnection of the three aspects of sustainability, namely environmental, social and economic. This framework is a useful and comprehensive tool for assessing country performances over time and improving guidelines for the classification of countries under a sustainability perspective. The method enables identification of trends and traps that characterize the evolution of countries over time. The analysis is performed for 83 countries in 2000 and 2008 in order to observe system behaviour and development patterns.

Abstract National economic systems are investigated in a 3-axis diagram where three different indicators are used to account for resource use, societal organization, and goods and services produced, respectively. This framework is consistent with an input-state-output (environment–society–economy) scheme based on a logical, physical and thermodynamic order between the three dimensions of sustainability. This approach highlights which input-state-output relations are realized and which relations are less common in the behavior of these systems. It assesses and overcomes major drawbacks of common representations of sustainability. Within a cube diagram, 99 national economies are ranked and grouped into 8 categories, which are labeled to reflect the main characteristics of their behavior according to the three environmental, social and economic parameters. A cluster analysis is also performed in order to statistically support the classification and strengthen the interpretation of results. Results show that no countries exhibit a dematerialization of economic activity and that non-sustainable economic activity can take place over a wide range of income distributions (Gini coefficients).
