Paris climate agreement, five years on: Reasons for optimism?

Laurence Tubiana is often described as the architect of the Paris climate agreement. But five years on, is it fair to say that not enough was promised in Paris and not enough has been done since? “I am more optimistic than I was seven months ago,” Tubiana tells FRANCE 24. The CEO of the European Climate Foundation shares the reasons for her cautious optimism.
