Lord Stern from Davos2015

Lord Stern said that this year’s event in Paris aimed at reaching a deal on climate change was crucial. “This year will shape the next 20... it is the poor who are hit hardest by climate change,” he said.

Following the press conference, the Guardian caught up with Lord Stern, walking around the corridors of the conference centre. He said the current low oil price (with Brent crude trading at just above $48 a barrel today) “was a very good moment for enlightened policy”.

“If you want to put a carbon tax on now is absolutely the right moment.”
