Nepal became a party of UNFCCC in 1992 and adopted Kyoto protocol in 1997 at the 3rd Session of the Conference of the Parties (COP) along with many other nations. After eight years the government formally endorsed this decision. In the year 2003, a small group of civil society organization based in capital started a dialogue with the government about the benefit of being party to climate change convention and its associated protocol. The main attraction at that time was Clean Development Mechanism under the Kyoto protocol. This small group was successful to convince the government and as a result the government endorsed the Kyoto protocol on December 2005.
 
The group with its first success in establishing the climate change issue at the national level, was later formally named itself as “Climate Change Network Nepal (CCNN)”.  This makes CCNN one of the oldest and pioneer networks on Climate change in Nepal. The network in its initial phase was very active in supporting the government as and when required. Gradually, the group expanded and ultimately it succeeded in bringing unique strengths of different agencies together.

At present, CCNN is working as a semi-formal network with its guiding document endorsed by its general consensus on 2009. It receives voluntary support from its member agencies in order to meet their operational and other incidental expenses. In-spite of their shapes and forms, this network is successful in establishing the ‘climate change’ issue in Nepal.
