Cambodia ratified to become a Party to the Stockholm Convention (SC) on 25th of August 2006, and commits to fulfilling its obligations under this treaty by taking various measures in order to meet objectives of the Convention. The Article 7 of the Convention requires Parties to update their National Implementation Plans (NIPs) to address old and new POPs as they are listed to the Convention annexes. Article 15 requires Parties to provide regular updates on progress in implementation of the SC through submission of National Reports every four years. Although national progress was made in implementation of Stockholm Convention, there are number of challenges facing the country in fulling its obligations under Article 7 and 15 due to limited data and quantitative information on the production of POPs available in the country as well as the difficulty in filling requested data and information under the Article 15 in report format online to be submitted to the Secretariat of Stockholm Convention. Thus this report will identify and present the overlaps and gaps between data and information requested under the reporting pursuant Article 15 and other reporting obligations under the Stockholm Convention and the data and information generated during the NIP development and/or update process, as well as conclusions and recommendations on modalities to correlate the processes of reporting under Article 15 and other reporting obligations under the Stockholm Convention with the process of developing and updating the NIPs.
