Brief history of UNFCCC and COP.

In 1992, during the Earth Summit in Rio de Janeiro, the United Nations Framework Convention on Climate Change (UNFCCC) was adopted. UNFCCC is a global treaty of 198 countries and territories that sets a framework for governments to tackle issues posed by changing climate. The convention aims to stabilize atmospheric concentrations of greenhouse gases (GHGs) at a level that would shield the climate system from harmful human involvement while allowing ecosystems to naturally adjust to climate change over an appropriate amount of time.
