The United Nations provides the main framework through which states negotiate, coordinate and review global responses to climate change. Through the United Nations Framework Convention on Climate Change (UNFCCC) and Conferences of the Parties (COPs), it advances mitigation, adaptation, climate finance and accountability.
How the UN System Works
The UNFCCC is an international environmental agreement adopted in 1992. It aims to prevent dangerous human interference with the climate system. It recognizes common but differentiated responsibilities: all countries share responsibility, but historical emissions, capabilities and vulnerabilities differ.
A COP is a meeting of UNFCCC parties. It can produce decisions, rules and agreements, while national governments remain primarily responsible for implementation.
| UN role | Mechanism or example |
|---|---|
| Set negotiating framework | The UNFCCC provides a continuing forum for international cooperation. |
| Establish commitments | The 1997 Kyoto Protocol set binding targets for specified industrialized countries. |
| Coordinate national action | The 2015 Paris Agreement requires countries to submit and strengthen nationally determined contributions (NDCs). |
| Monitor progress | Reporting, transparency procedures and the global stocktake review collective progress. |
| Support implementation | Climate finance, technology transfer and capacity-building assist vulnerable countries. |
| Inform negotiations | The Intergovernmental Panel on Climate Change (IPCC) assesses evidence but does not set policy. |
The UN does not function as a world government. A common misconception is that COP decisions automatically force every state to cut emissions. Outcomes depend on state consent, domestic implementation, finance and political willingness; consensus-based negotiations may also weaken or delay action.
Exam Technique
This is HL-only content in Subtopic 6.3, Climate change mitigation and adaptation. In an ESS response, distinguish the UNFCCC framework from COP meetings, use a named agreement such as Paris, and evaluate both coordination and limitations. Link climate finance and differentiated responsibility to environmental justice, because highly vulnerable countries may have contributed least to climate change.
