Every three years, CITES hosts a meeting of the Conference of the Parties (COP). At each COP, the Parties consider and vote on proposals to add or delete species from the Appendices I and II and interpret the treaty language by adopting Resolutions and Decisions.

For each COP, SSN prepares the 'CITES Digest', an invaluable guide to the species proposals and working document to be considered at the COP. In addition, SSN produces a helpful series of factsheets on the meeting's key topics.
