So far, a personal carbon quota system is the best idea I've heard for managing carbon dioxide emissions. It's also refered to as Domestic Tradable Quotas (DTQs) or Tradeable Energy Quotas (TEQs) or Personal Carbon Allowance (PCA). Think of it as a personal pollution allowance/quota/ration.
The idea is you get a fixed number of units per year recorded on a plastic card. Units get debited when you buy goods or services. You can argue about the details but assume everything has a money price and a carbon price. The carbon units are a currency in their own right that can be bought, sold, earned and traded. Of course it won't be perfect and there will be a huge black market but it's the best mechanism I've heard of for creating a CO2 bound economy that leaves consumers with the greatest choice.
I think it would be a more dynamic approach than carbon taxes which are a more blunt way of suppressing polluting activities. A personal quota provides a direct way of encouraging and rewarding green actions. You could even make money selling surplus carbon units. But it also allows you limited indulgence in polluting luxuries without raising the cost of them in "old" money.
Some will argue that such a scheme is too complex to run. Maybe. Maybe not. It depends on the details. I think it's worth pursuing further.
