Vowing the India's commitment to fight global warming, Environment Minister Prakash Javadekar signed Paris climate change agreement calling it "the triumph of collective wisdom" in the global race to save the planet.
Crucial element of the agreement that UN Secretary-General Ban Ki-moon called "the covenant with the future" is a global effort to keep the rise in global temperatures below 2 degrees centigrade compared to the pre-industrial era level.
After a parade of 175 leaders signed the agreement, the largest number of nations ever to sign such a pact at one time, Ban declared, "When I look out at the horizon, I see, more clearly than ever, the outlines of a new and better world."
Speaking at the ceremony, Javadekar made a plea for "sustainable lifestyles and sustainable consumption" and for climate justice, both of which are in the agreement's preamble. "We must chalk up our action plans to implement the Paris Agreement based on these two features," he said.
"If we continue with unsustainable consumption patterns, we will require three planets," he warned. "But we don't have three, we have only one planet, which people call mother earth. We must, therefore, take care of this one mother earth."
Children representing 197 countries wearing shirts that read, "Your promise, our future," made their generation's case for the environment. US Secretary of State John Kerry held his two-year-old granddaughter Isabelle Dobbs-Higginson on his lap as he signed the agreement to emphasize the inter-generational responsibilities.
