"What we need is a global people's movement to bring about behavioural change," Modi said at the Climate Action Summit convened by UN Secretary General Antonio Guterres.

"Not enough is being done to combat climate change. We need a comprehensive approach through education, values, lifestyle approach and behavioural change, which should be turned into a mass movement," he said.

Guterres, who said that "around the world, nature is striking back with fury", said that "the ticket to entry" at the summit "is not a beautiful speech, but concrete action".

He said: "And you are here with commitments. Governments are here to show you are serious about enhancing Nationally Determined Contributions under the Paris Agreement."

Modi was third speaker among the first batch of four.

President Donald Trump, who was boycotting the Climate Action Summit and holding a parallel meeting on religious freedom, unexpectedly dropped in while Modi was speaking.

Taking up Guterres's challenge Modi said: "Need not greed has been our guiding principle and therefore India is here today not just to talk about the seriousness of this issue, but to present a practical approach and a roadmap."

Modi said: "We believe that an ounce of practice is worth more than a ton of preaching."

Outlining India's commitments, he said that India will increase its share of non-fossil fuel in its fuel mix and "increase by 2022 our renewable energy capacity to 175 gigawatts, and we are committed to further increasing this to 450 gigawatts".

"We are encouraging e-mobility in our transport sector. India is also looking to considerably increase the percentage of the biofuel blended in petrol and diesel."

India is also leading action at the international level against climate change, he said.

"About 80 countries have joined our International Solar Alliance initiative and very pleased that India and Sweden together with other partners are launching the leadership group within the industry transition track by bringing the governments and the private sector together this initiative will play an important role in developing low carbon pathways for industry," he said.

He had won the youth pitch initiative aimed at industry leaders with his proposal for system of crowdsourcing weather agriculture data for farmers.
