Naderev "Yeb" Sano -- a former envoy to UN climate talks who came to world attention in 2013 by fasting to highlight the threat of global warming -- said he hopes his "People's Pilgrimage" will put pressure on delegates to reach agreement at the UN Conference on Climate Change in December.
"It will take a huge amount of effort and an unprecedented amount of political will to arrive at an agreement in Paris," Sano told AFP.
Asked if he was hopeful of a climate deal this year, Sano said: "I don't think we can gauge that today. Our fate is in the hands of a few people. The challenge is to make them listen."
Delegates to the conference will try to achieve, for the first time in over 20 years of UN negotiations, a binding and universal agreement on climate climate.
