I agree, international consumption is causing a lot of drive in consuming limited resources. A carbon trade market would go a long way to redirecting those free market impulses in a more sustainable direction.
A problem I see is the growing rejectionism of climate science and all the attendant solutions. I have had conversations with a number of educated individuals who will cling to the contrarian view, finding shelter in the notion that 'we simply don't know how much of this is man made'.
I believe a large part of this thinking is a result of efforts by petroleum co's trying to stave off a shift away from petroleum. Carbon trading schemed are so much white noise to the converts of rejectionism.
I agree. I have learned to lead with the economic advantages of insulation, and other energy conserving options (you will save this much money) and often don't even bring up the social and environmental benefits, unless the customer or audience is wanting to hear it. Some people will reject a product that has a permanent 50% annual ROI if they hear it is "environmentally good". Incandescent light bulb loyalty is a good example.
Some kind of carbon support would vastly accelerate the shift from fossil fuels - they'd be dead in ten years - that's why it won't happen. Instead the planet will be dead in 50 years!
Oh, the logic of capitalism and "free" markets!
