The Triple Bottom Line

The triple bottom line (abbreviated as "TBL" or "3BL", and also known as "people, planet, profit") captures an expanded spectrum of values and criteria for measuring organisational (and societal) success: economic, ecological and social. With the ratification of the United Nations and ICLEI TBL standard for urban and community accounting in early 2007, this became the dominant approach to public sector full cost accounting. Similar UN standards apply to natural capital and human capital measurement to assist in measurements required by TBL, e.g. the ecoBudget standard for reporting ecological footprint.

In the private sector, a commitment to corporate social responsibility implies a commitment to some form of TBL reporting. This is distinct from the more limited changes required to deal only with ecological issues.
