There's a contradiction here at the U.N. climate summit in Paris. And it's been bugging me.
So I stopped a woman at random, Liz Hanson, from Whitehorse, Yukon, in Canada, and asked her about it.
She flew a long way to get here — 12 or 13 hours.
"Big carbon footprint for that, right?" I asked her.
"I would say there probably really is," she said.
