The United Nations Framework Convention on Climate Change (UNFCCC) is an international government treaty first adopted at the Earth Summit in Rio de Janeiro in 1992. The framework's objective is to prevent dangerous interference with the global climate through stabilising the levels of greenhouse gas found in the atmosphere. The UNFCCC has 197 parties With no legal enforcement mechanisms of its own, the UNFCCC helps negotiate treaties that drive countries to take action on climate change that will help achieve the framework's objective of stabilising global emissions. The parties of the convention have met annually since 1995. The most recent COP took place in Paris 2015 where 197 parties signed a landmark agreement to tackle climate change collectively and keep global temperature rise below 2 degrees. Find out more.
