The business management approach to sustainability has been largely shaped by the sustainability programs and policies of international development organizations, federal, state and local governmental regulatory organizations, consumer advocacy groups, as well as organized bodies and other environmental private organizations. The Brundtland Commission created the overall concept of sustainable development in 1987. Following the Brundtland Report, international organizations such as the Global Reporting Initiative (GRI) have established sustainability reporting guidelines on how to document and prepare a company's economic, environmental and social performance. Corporate social responsibility (CSR) is part of sustainability reporting which is prepared to document the continuing commitment by business to behave ethically and contribute to economic development while improving the quality of life of the workforce and their families as well as of the local community and society at large. In accounting, the disclosure of economic, social and environmental reports is broadly classified as triple bottom line (TBL) reports that are included in external annual accounting reports.
