Key recommendations

  • Before speaking with a member of the press or posting information on social media, please ensure that the information you are about to share can be made public.
  • For some sessions, the President of the CGPM may ask delegations to refrain from sharing updates about the discussions with the press or on social media.
  • Please refrain from directly quoting other delegates or taking their photographs without their consent.
  • Ensure that any photographs shared on social media can be made public, and if so, that any photograph not taken by you includes the necessary credit/copyright information.
