Although the concept of sustainable development may be clear enough at a sufficiently high level of abstraction, not so clear are its practical, day-to-day, policy implications. In the preparations for UNCED this was clearly understood. The action programme of UNCED, Agenda 21, thus calls for the development of indicators for sustainable development, rather than for precise measurement. In fact, Agenda 21 argues that ‘Indicators of sustainable development need to be developed to provide solid bases for decision-making at all levels and to contribute to a self-regulating sustainability of integrated environment and development systems’ (UNCED, 1992). Indicators are bits of information that highlight what is happening in the large system; they are small windows that provide a glimpse of the ‘big picture’ (Sustainable Seattle, 1996).
