Yes, we know you feel that way :)
It's just dumb to think that you can punish an individual into significantly changing their carbon footprint. Individuals basically have no say in the matter. They buy the cars that are available on the lot; they heat their house with the energy provided to them by the (typically only) Energy Company; they aren't able to travel on the non-existant tram lines.
If there's one thing we're sure of it's that the missing ingredient in NOT the individual.
