The following is data currently in the IEA database for agreement actions. Agreement actions (signature, ratification, entry into force) can change frequently. The IEA Database Project updates this data approximately once a year and tries to ensure it is current and accurate. You are encouraged to visit the Ozone Secretariat website to look for the most accurate and up-to-date membership information. If you have questions about this data or notice inaccuracies, please contact the Project Director.
This amendment was adopted under a provision of the agreement being amended that allows for entry into force via their “tacit acceptance,” for all countries that do not object in a specified period of time. The membership information here has been inferred based on membership in the agreement being amended.

Membership status is coded as follows:

  • Countries listed are those that have signed and/or ratified the IEA in question.
  • Legend:
    • 0 (pink): Signer: country signed but did not ratify IEA. Status is 0 for all countries until IEA enters into force.
    • 1 (yellow): Ratifier: country signed and ratified IEA but IEA had not entered into force. Status is 1 for countries that have ratified until IEA enters into force.
    • 2 (green):Member: country signed and ratified IEA and IEA has entered into force for that country.
    • Ratifier row is count of states that have ratified.
    • Membership row is count (not sum) of members.
  • If membership data source lacks entry into force date, membership is inferred from year of ratification, if that year occurs after entry into force year of IEA.
  • Status can return to 0 if an IEA is terminated or if a country withdraws. In rare cases, countries later re-join IEAs, with their status returning to 2.
  • Action tab: membership by Action, Country, Year, Month, Day.
  • Wide tab: Annual status data (countries as rows, years as columns).
  • Long tab: Annual status data in Stata format (Country, Year, Membership Status).
