In The Magnificent Seven Deadly Sins, a comedy made in 1971, Spike Milligan portrays Sloth as a tramp trying to get through a farm gate. This simple task is rendered almost impossible by the fact that he can’t be bothered to take his hands out of his pockets and open the latch. He tries everything: getting over it, under it, through it, hurling himself at it, risking mortal injury, expending far more energy and effort than the obvious solution would require.
This is how environmental diplomacy works. Governments gather to discuss an urgent problem and propose everything except the obvious solution – legislation. The last thing our self-hating states will contemplate is what they are empowered to do: govern. They will launch endless talks and commissions, devise elaborate market mechanisms, even offer massive subsidies to encourage better behaviour, rather than simply say “we’re stopping this”.
