ability measurement is the quantitative basis for the informed management of sustainability. The METRICS used for the measurement of sustainability (involving the sustainability of environmental, social and economic domains, both individually and in VARIOUS combinations) are still evolving: they include indicators, benchmarks, audits, indexes and accounting, as well as assessment, appraisal and other reporting systems. They are applied over a wide range of spatial and temporal scales.Some of the best known and most widely used sustainability measures include corporate sustainability reporting, Triple Bottom Line accounting, and estimates of the quality of sustainability governance for INDIVIDUAL countries USING the Global Green Economy Index (GGEI), Environmental Sustainability Index and Environmental Performance Index. An alternative approach, used by the United Nations Global Compact Cities Programme and explicitly critical of the triple-bottom-line approach is Circles of Sustainability.please keep me has brainleist
