I agree that individuals should participate in carbon trading. National governments keep setting new targets for reducing emission. I read just today in the news that the United Kingdom government is trying to reduce their emissions by 60% to 80% until 2050.
The major industries are already participating in carbon trading and the government can only go so far by implementing this policy just for industries. At some point, they need to have households participate too. I think that only with personal carbon trading can we reach the emission reductions we are aiming for.
