Concept
Sustainability measurement
Résumé
Sustainability measurement is a set of frameworks or indicators to measure how sustainable something is. This includes processes, products, services and businesses. Sustainability is difficult to quantify. It may even be impossible to measure. To measure sustainability, the indicators consider environmental, social and economic domains. The metrics are still evolving. They include indicators, benchmarks and audits. They include sustainability standards and certification systems like Fairtrade and Organic. They also involve indices and accounting. And they can include assessment, appraisal and other reporting systems. These metrics are used over a wide range of spatial and temporal scales. Sustainability measures include corporate sustainability reporting, Triple Bottom Line accounting. They include estimates of the quality of sustainability governance for individual countries. These use the Environmental Sustainability Index and Environmental Performance Index. Some methods let us track sustainable development. These include the UN Human Development Index and ecological footprints.
Two related concepts to understand if the mode of life of humanity is sustainable, are planetary boundaries and ecological footprint. If the boundaries are not crossed and the ecological footprint is not exceeding the carrying capacity of the biosphere, the mode of life is regarded as sustainable.
A set of well defined and harmonized indicators can help to make sustainability tangible. Those indicators are expected to be identified and adjusted through empirical observations (trial and error). The most common critiques are related to issues like data quality, comparability, objective function and the necessary resources. However a more general criticism is coming from the project management community: "How can a sustainable development be achieved at global level if we cannot monitor it in any single project?".
Sustainable development has become the primary yardstick of improvement for industries and is being integrated into effective government and business strategies.
