We could tax use of fossil fuels. That means direct consumption, if you drive a car, or indirect if you buy products shipped on fuel hungry ships, or strawberries flown in from half way around the world, and not least electricity from a gas fired power station wherever it is situated. Since we in the G20 consume most of the energy and goods, then we would be paying the most penalty for this. We would have to trust that our governments actually did something with the money though, not just put it in with general revenue and let the future deal with the problems it was supposed to be paying for.
