The regional technical assistance (TA) RETA 7566: Strengthening and Use of Country Safeguard Systems (CSS) included a review of Papua New Guinea (PNG) environmental legislation with regard to equivalence with the environment safeguards covered in Asian Development Bank’s Safeguard Policy Statement 2009 (SPS). The overall CSS assessment procedures to be adopted in subprojects implemented under the RETA were presented in a workshop in November 2011. The second phase reviewed the implementation of CSS procedures within the PNG context and adopting the energy sector as the area for case study. The Department of Environment and Conservation (DEC) was identified as the responsible agency at the national level and PNG Power (PPL) was chosen as the implementing agency at the sector level. The third phase is the preparation of an Action Plan (AP) which addresses the gaps identified and which would improve the application of CSS within PNG. This report provides the final AP as elaborated with DEC and PPL following the workshop held in August 2012.
