UNFCCC provides the central global forum for normative work on climate change. The mandates it issues, together with relevant mandates issued by other intergovernmental bodies across the UN system, set the goals and standards towards which multilateral action on climate change aims.

Climate knowledge developed or disseminated by UN system entities provides the scientific basis for decision making. Public information activities increase awareness of governments and the broader public and contribute to strengthening the international consensus for decisive action.
