Cheatneutral is a spoof website that takes the mick out of the idea that we can save the planet by trading carbon emissions. Here’s the comparison. "At Cheatneutral, we believe that we should all try to reduce the amount we cheat on our partners, but we also realise that fidelity isn’t always possible. That’s why we help you neutralise your cheating…By paying Cheatneutral, you’re funding monogamy-boosting offset projects – we simply invest the money you give us in monogamous, faithful or just plain single people, to encourage them to stay that way."
