The story was entirely incidental to showing off cool tech and exciting action scenes. We might as well discuss his anti-technology stance in Terminator 2.

I think you're missing the point if what I said. Lots of things are economically viable to a corporation if it can externalise the downsides (either by dumping the wastes or getting a bailout when it make mistakes) or simply get the legislation that favours it (google "oil industry tax breaks" for an example).

You can't get away from legislation. Bailouts are legislation. But making polluters pay requires legislation. There is no mythical free, unlegislated market that will magically do the right thing. There's only good legislation and bad legislation.

Aren't there other more pressing forms of pollution than CO2 emmisions? What about strip mining, particulate emissions, and methane? Is this really about curtailing emissions, or creating a lucrative secondary trading market and taxation system to benefit people like Al Gore who are both heavily invested in carbon trading, and part of the legislature.
