India signed and ratified Kyoto protocol in which year?

Year 2002

The correct answer is Option 2 - Year 2002

India signed and ratified the 1997 Kyoto Protocol in August 2002. India, China and other developing countries were exempt from the requirements of the Kyoto Protocol because their contribution to the emission of greenhouse gases during the industrialisation period (that is believed to be causing today’s global warming and climate change) was not significant.
