About the Charter Secretariat

The establishment of the Secretariat for the Climate and Environment Charter for Humanitarian Organisations was announced at COP28 in Dubai in December 2023. The Charter Secretariat serves as a referral hub to support and connect organisations to implement the Charter commitments through its four core areas:

  1. Connect signatories to experts and resources within and beyond the Charter network to access technical guidance in implementing Charter commitments.
  2. Serve as a knowledge-sharing platform to share Charter-related resources, collaborate in developing knowledge products, and exchange lessons learned and best practices from the Charter community.
  3. Strengthen communications and engagement with Charter signatories through developing and enhancing platforms for partnership, learning, and coordination.
  4. Promote, disseminate, and advocate for the Charter, and the implementation of its commitments, within the humanitarian community.

Across these areas, the Charter Secretariat will:

  • Support Signatories to navigate existing and relevant guidance, tools and information available on the Charter website and beyond;
  • Connect Signatories with existing expertise and resource centres on a variety of strategic, technical and programmatic subjects;
  • Organise webinars and workshops to share lessons learned and best practices from organisations that have already implemented programmes or developed targets, plans of action, strategies etc. and provide support to communities of practice;
  • Co-create and develop knowledge products, informed by the needs of Charter Signatories, that will highlight case studies, best practices, and lessons learned on the implementation of commitments;
  • Share and disseminate relevant information on the latest developments, initiatives, guidance, and events related to climate, the environment, and humanitarian action; and
  • Promote, disseminate, and advocate for the Charter across the humanitarian sector

Governance and Administration

The Charter Secretariat is administered by the International Council of Voluntary Agencies (ICVA) and a Board, which serves as a governance mechanism. The board includes three permanent members: the International Federation of Red Cross and Red Crescent Societies (IFRC), the International Committee of the Red Cross (ICRC), and ICVA – who together led the development of the Charter. Two other signatory organisations and one State supporter will serve as non-permanent members on a rotating basis. The inaugural board will be announced in June 2024.
