Trying to measure how sustainable an organization was use to be challenging undertaking. However, during the 1990s, a concept brought up by American John Elkington change the way sustainability was measured. This framework is known as the triple bottom line (TBL) and measures sustainability in relation to organizational performance and investment against the 3Ps (1) Profits (2) People (3) Planet. For example; Profit: A packaging manufacturer reinvesting its profits in State- of-the-art recycling machinery for it wasted cardboard.
People: A large privately owned call centre donate its end of life computers to a local youth clubs and social groups to help gain internet cases.
Planet: A driving instructors using only hybrid vehicles to teach her learners, thus to reducing Co2 emission.
