Developers of new indicators are asked to decide if an indicator has something to do with resource use, infrastructure or society needs or if these aspects are combined. Check the categorisation of the indicator. The selection of sustainability indicators requires the consideration of different spatial structures. Indicators and evaluation criteria should be assigned to their spatial reference. If possible, the spatial reference of an indicator should be named and visualised.
Sustainable development is a long-term concept.
Indicators should not only describe the present status but also visions and future objectives. Try to estimate if the indicator points to long-term solutions. The evaluation criteria should be comprehensible and logic. Please evaluate the quality of evaluation criteria. Therefore time series data should be preferred.
