Bilateral & Multilateral Agreements

Article 8 of the Convention (Bilateral and Multilateral Co-operation) states "The Parties may continue existing or enter into new bilateral or multilateral agreements or other arrangements in order to implement their obligations under this Convention. Such agreements or other arrangements may be based on the elements listed in Appendix VI" (Elements for Bilateral and Multilateral Co-operation).
Guidance on the Practical Application of the Espoo Convention, adopted in June 2004   ENG+FRE+RUS

Regarding bilateral and multilateral agreements, the Guidance notes that there are many issues that can be agreed upon in advance by Parties that expect to have transboundary assessments on a regular basis. The Convention provides a legal basis for agreements (Article 2, para. 2, and Article 8). Appendix VI to the Convention contains elements for such agreements. These agreements are not a precondition for the application or ratification of the Convention but should be seen as a way of achieving effective application.
