* The United Nations Framework Convention on Climate Change (UNFCCC) is the main international treaty on climate change. The UNFCCC requires countries to submit national climate plans, known as Nationally Determined Contributions (NDCs), every five years. These NDCs are then assessed by the UNFCCC Secretariat, which publishes a report on their adequacy and progress.
* The Intergovernmental Panel on Climate Change (IPCC) is a scientific body that provides assessments of the scientific, technical and socio-economic aspects of climate change. The IPCC does not assess individual countries' climate plans, but its reports can be used to inform the development and assessment of these plans.
* Climate Action Tracker (CAT) is an independent scientific analysis produced by two research organizations tracking government climate action and measuring it against the internationally agreed Paris Agreement goals. CAT tracks the emission reduction pledges made by countries and assesses the progress made by each country towards meeting their goals.
* The World Resources Institute (WRI) is a global think tank that provides research and analysis on climate change and other environmental issues. WRI publishes a number of reports and tools that assess countries' climate plans, including the Climate Policy Tracker and the Global Climate Index.
These are just a few of the many different mechanisms through which countries' climate plans are assessed and evaluated. The purpose of these assessments is to help countries track their progress towards meeting their climate goals and to identify areas where they can improve their efforts.
