United Nations Framework Convention on Climate Change

The UNFCCC is one of the three Rio Conventions, adopted at the 1992 Rio Earth Summit and in force since 21 March 1994.

The UNFCCC now has 198 Parties — near-universal membership. Its ultimate goal: stabilize greenhouse gas concentrations at a level that prevents dangerous human interference with the climate system. This means achieving a balance that allows ecosystems to adapt naturally, safeguards food production and supports sustainable economic development. The Convention has facilitated significant global agreements such as the Kyoto Protocol and the Paris Agreement.

What UNFCCC does

  • Recognizes the problem – Even in 1994, with less scientific certainty than today, Parties committed to act in the interests of human safety
  • Sets a clear objective – Prevent dangerous climate change within a timeframe that protects ecosystems, food security and economies
  • Mobilizes finance and technology – Industrialized countries provide funding, technology transfer, and capacity-building to help developing nations take climate action
  • Tracks progress – Developed countries report regularly on policies, measures, and greenhouse gas emissions; developing countries share actions taken, supported by available resources
  • Addresses adaptation – The Convention acknowledges all countries’ vulnerability to climate change, with special focus on those lacking resources to adapt

UNFCCC and Rio Synergies

The UNFCCC’s mandate directly intersects with biodiversity and land management. Through the Joint Liaison Group, the Rio Conventions work together on shared priorities like drought resilience, food security and ecosystem restoration.

The UNFCCC supports integrated solutions that tackle climate change, biodiversity loss and land degradation together, including:

  • Nature-based solutions – Protecting and restoring ecosystems to absorb carbon, conserve biodiversity and enhance resilience
  • Sustainable land use – Ensuring agriculture, forestry and other land uses maintain ecosystem health
  • Ecosystem-based adaptation – Using natural systems to help communities adapt to climate impacts

Key UNFCCC processes — Nationally Determined Contributions (NDCs), National Adaptation Plans (NAPs) and the Global Stocktake — increasingly promote these cross-cutting approaches.

By fostering collaboration among national focal points, aligning science and policy, and mobilizing finance, the UNFCCC helps Parties deliver climate strategies that provide multiple environmental and social benefits.
