When French energy minister Ségolène Royal stepped onto the conference stage yesterday, she was visibly proud when she pointed out that the Paris Agreement will come into force today.

But after briefly congratulating herself for the achievement (she was the president of last year’s COP21 where the deal was agreed), she then proceeded to point out that the much-lauded agreement is little more than a template in which most of the text still needs to be written.

Or as she put it: “The agreement set down ambitions, principles and goals; we [now] need to translate them into detailed provisions.”
