Triple Bottom Line
Triple bottom line is John Elkington's term for three separate bottom lines - financial, social, and environmental - of companies. He had coined this term in 1994 to measure the economic value of a company in terms of "people account" and "planet account". People account measures the company's degree of social responsibility, while the planet account measures the company's environmental responsibility. Elkington argued that companies should prepare triple bottom line rather than focusing solely on their finances.
