Which is why a carbon price is so essential. Even if all the information was readily available to consumers, its too complex to be able to interpret.

Sure, I’d be interested in seeing actual data. Which is why I qualified my statement with “probably” because of course I have anecdotes that counter your anecdotes. :) I just don’t have the time to look into any primary sources.

Those milieus who care most about the environment consistently turn out to have the highest environmental footprint. The point isn't that these people are hypocrites. Maybe they are (who, besides a cynic, isn't to some degree?), maybe they are not. The point is that it doesn't matter at all. People by and large will not alter their behavior in any major way for a common good as long as the individual marginal advantage is dwarfed by the individual marginal cost. Fishers will happily eradicate all fish in their fishing grounds and thus destroy their own livelihood, and will fiercely protest any meaningful regulation aimed at conserving. Consumers will happily fly around the world or commute in a SUV until the planet is doomed.^1

It's just the way it is, lamenting the sinful human nature doesn't change a thing. We need meaningful regulation.
