do we present them in ways that are simple, elegant and effective, withoutcompromising the un<strong>de</strong>rlying complexity?A single indicator of sustainable <strong>de</strong>velopment is an impossible dream. The bestway to overcome this problem is to combine the indicators into indices.Assessments that do not combine their indicators into indices are extremelyhard to interpret. Assessments that do, can communicate their main findingsvery readily. When indicators are combined into indices, they can provi<strong>de</strong> a clearpicture of the entire system, reve<strong>al</strong> key relationships between subsystems andbetween major components, and facilitate an<strong>al</strong>ysis of critic<strong>al</strong> strengths andweaknesses. No information is lost, because the constituent indicators andun<strong>de</strong>rlying data are <strong>al</strong>ways there to be queried.Wellbeing Assessment combines ecosystem indicators in an EcosystemWellbeing In<strong>de</strong>x (EWI) and human indicators into a Human Wellbeing In<strong>de</strong>x(HWI), which are then combined graphic<strong>al</strong>ly into a Wellbeing In<strong>de</strong>x (WI) – theintersection of the EWI and HWI on the Barometer of Sustainability.The Dashboard of Sustainability comes in two versions. The standard versioncombines environment<strong>al</strong> indicators in an Environment In<strong>de</strong>x (EnI), economicindicators into an Economy In<strong>de</strong>x (EcI) and the soci<strong>al</strong> indicators into a Societyor Soci<strong>al</strong> Care In<strong>de</strong>x (SI), which it then combines into a Policy PerformanceIn<strong>de</strong>x (PPI). The version for the indicator set of the CSD combines institution<strong>al</strong>indicators in an Institution<strong>al</strong> In<strong>de</strong>x (II) and then combines the EnI, EcI, SI, andII in a PPI.By combining indicators into indices and displaying the indices graphic<strong>al</strong>ly, bothWell-being Assessment and the Dashboard of Sustainability show how closethe society concerned is to sustainability, the state of people (socio-economicconditions) and the ecosystem (environment<strong>al</strong> conditions), and the main strengthsand weaknesses of <strong>per</strong>formance.The last <strong>de</strong>ca<strong>de</strong> has seen consi<strong>de</strong>rable efforts by governments, NGOs andmulti-stakehol<strong>de</strong>r groups to <strong>de</strong>velop indicator-based assessments of sustainable<strong>de</strong>velopment. Some cover the full sweep of sustainability. Most tend to paymore attention either to human aspects or to the environment.
