United Nations Framework Convention on Climate Change (UNFCCC)

Core objectives and principles

At its heart the UNFCCC aims to reduce the risk of human activities causing harmful climate change by promoting mitigation, adaptation and international cooperation. The Convention embodies key principles such as common but differentiated responsibilities and respective capabilities, reflecting the idea that developed and developing countries have different historical contributions to emissions and differing abilities to respond. The concept of climate as an interconnected system is central to negotiations and action: climate.

Parties, meetings and institutions

Nearly every country is a Party to the UNFCCC, forming a global membership that meets annually at the Conference of the Parties (COP). The COP reviews implementation, adopts decisions, and provides political direction. The treaty is supported by a permanent secretariat located in Bonn and by subsidiary bodies that handle scientific, technical and financial issues. Current membership details and resources are available here: membership.

Mechanisms and related agreements

The Convention itself establishes reporting, review and information-sharing processes. Over time it has been complemented by legally and politically important instruments negotiated under its framework, including the Kyoto Protocol and the Paris Agreement. These instruments created mechanisms such as emissions targets for some Parties, market approaches, and the nationally determined contributions (NDCs) central to the Paris architecture. Parties coordinate policy responses to reduce global warming and increase resilience: policy meetings and global warming.

• National communications and greenhouse gas inventories
• Adaptation planning and finance
• Transparency frameworks and periodic reviews

Since its inception the UNFCCC has shaped international climate diplomacy, provided a platform for scientific guidance, and mobilized finance and technology transfer. While it does not prescribe a single path for every country, it remains the central arena where states negotiate collective responses to the global challenge of climate change.
