Governing and subsidiary bodies
The Convention, the Kyoto Protocol, and the Paris Agreement established three governing bodies: the COP for the Convention, the CMP for the Kyoto Protocol and the CMA for the Paris Agreement. The Bureau of the COP, the CMP and the CMA supports the work of the governing bodies. The UNFCCC secretariat provides organizational support and technical expertise.
Two permanent subsidiary bodies – the SBSTA and the SBI – assist the governing bodies.
The COP, the CMP and the CMA furthermore establish other ad hoc subsidiary bodies as deemed necessary to address specific issues.

About the secretariat

The UNFCCC secretariat provides organizational support and technical expertise to the UNFCCC negotiations and institutions and facilitates the flow of authoritative information on the implementation of the Convention, the Kyoto Protocol and the Paris Agreement. This includes the development and effective implementation of innovative approaches to mitigate climate change and drive sustainable development.

The secretariat is institutionally linked to the United Nations without being integrated into any programme and is administered under United Nations rules and regulations.
Subsidiary bodies
Subsidiary Body for Scientific and Technological Advice (SBSTA)

The SBSTA assists the governing bodies through the provision of timely information and advice on scientific and technological matters as they relate to the Convention, the Kyoto Protocol and the Paris Agreement. In addition, the SBSTA cooperates with relevant international organizations on scientific, technological and methodological questions.
Subsidiary Body for Implementation (SBI)

The SBI assists the governing bodies in the assessment and review of the implementation of the Convention, the Kyoto Protocol and the Paris Agreement. In addition, the SBI considers the biennial work programmes for the secretariat, which provide the strategic direction on how the secretariat can best serve the Parties and the UNFCCC process.
