" ...No, no, Prime Minister. That's the beauty of it. We don't actually have to do anything; well, nothing during your term in office, nor for the Parliament following. Nothing at all until 2020, when whoever is in government will need to have a cunning plan to cut emissions."
"No, not a penny. Not for years and years. Yes, of course we can make sure Squiffy and Bunty get big contracts for their windmills - we're doing that already. And remember the bird-choppers only have an economic life of five years at sea, so it's pretty much a dosh-for-life deal ..."
"Well I suggest we sign up our future unknown successors to the max deal we can come up with; after all, we'll get all the kudos and they'll get nothing but a kicking if they don't meet the target"
"Thank you Prime Minister, that would be most welcome".
