SSI by TH Köln
The SSI shows at a glance the level of sustainability of countries along three dimensions:
Human wellbeing (HUW)
Environmental wellbeing (ENW)
Economic wellbeing (ECW)
The SSI is structured along the lines of the Triple Bottom Line of social (HUW), environmental (ENW) and economic (ECW) sustainability. HUW consists of three categories based on nine indicators. ENW consists of two categories based on seven indicators. Finally, ECW consists of two categories based on five indicators.All scores are given on a sustainability scale of 1(weakest) to 10 (strongest). There is no overall sustainability score, which would combine the three dimensions.
