Reports, research and evidence

The UK does research and analysis to inform our work and to manage the risks posed by POPs. You can find previous research published on Defra Science Search.

The Stockholm Convention requires the UK to:

  • develop, review and periodically update a National Implementation Plan (article 7)
  • report statistical data on its total quantities of production, import and export of each of the chemicals listed in Annex A and Annex B (article 15)

Read the UK National Implementation Plan on the Stockholm Convention website.
