SDPI was founded in August 1992 on the recommendation of the Pakistan National Conservation Strategy (NCS), also called Pakistan's Agenda 21. The NCS placed Pakistan's socio-economic development within the context of a national environmental plan. This highly acclaimed document, approved by the Federal Cabinet in March 1992, outlined the need for an independent non-profit organization to serve as a source of expertise for policy analysis and development, policy intervention, and policy and program advisory services. SDPI is registered under the Societies Registration Act, XXI of 1860.
