I agree with your sentiment. Unfortunately, exhortations to "do the right thing" never, ever seem to work.

And efforts to ban or control the trading of a liquid, globally used asset also never seem work. (It would be like trying to ban the buying and selling of, say, US dollars.)

Perhaps the best way to address the very real environmental issues you raise will be with the development and adoption of more cost-efficient, less polluting, more environmentally-sustainable energy production technologies?
