The word sustainability is derived from the Latin sustinere (tenere, to hold; sus, up). However, since the 80s sustainability as a term is being used more with respect to human sustainability on planet Earth. Although, the word sustainability is applied mainly to human sustainability on Earth, it is often used in many other situations and contexts.
From small local ones to the global balance of production and consumption, it implies responsible and proactive decision-making and innovation that minimizes negative impact and maintains a balance between social, environmental, and economic growth.
A universally accepted definition of sustainability remains elusive because it is often linked with other concepts such as “sustainable development”.
At the 2005 World Summit on Social Development, it was noted that this requires the reconciliation of environmental, social equity and economic demands – the “three pillars” of sustainability or the 3 E’s.
