The Government of Sri Lanka launched the Sustainable Cities Programme (SCP) under the auspices of UN-HABITAT & UNDP in December 1999. The initial objective was to help three municipal councils located in the Greater Colombo Core Area to experiment with and develop institutional mechanisms and approaches to build participatory processes to environmental planning and management (EPM).
The three municipal councils selected for the programme were Colombo, Sri Jayawardenapura-Kotte and Dehiwala-Mount Lavinia.
