Samenvatting
A key to sustainability in cities has been identified as all three pillars of environmental sustainability (stewardship), social equity and economic efficiency working together. Therefore an effective sustainability performance requires all three pillars to achieve complementary outcomes rather than simply individual outcomes. This paper discusses a sustainability challenge for cities and introduces some visualisation methods for sustainability performance assessment.
