India is to push for a second extension of Kyoto Protocol -- the legally binding framework on reducing emissions by developed countries -- at forthcoming climate change summit in South Africa, local media reported Friday.

"One of the important principles enshrined in the UN Framework Convention on Climate Change is the principle of common but differentiated responsibility and a concrete manifestation of this principle is the Kyoto Protocol... Our endeavour is to strive for developed countries to agree to extension of it," Indian Environment Minister Jayanthi Natarajan was quoted as saying Thursday.

The minister also said that all developing countries have been looking forward for operationaliztion of decisions taken at the climate change conference in Mexico last year.

Kyoto Protocol expires in December 2012.
