New Years resolutions
... It's just like you go to the gym, and then on your way home you say to yourself "Well, I earned myself some fish 'n chips". Except of course the Paris agreement is actually a collection of largely non- binding aspirations for the future. So this is more like saying "I really must go to the gym more often... Well, that's earned me some fish 'n chips!"
Nice analogy of the COP21 by John Finnemore in BBC’s The Now Show of 18 Dec, referring to the fact that just a few days after David Cameron (prime minister of the UK) came back from the climate negotiations, he changed the law about fracking under British National Parks.
