So, true as it may be that consumers are wary, (and justifiably so), about what the practical applications of a better understanding of carbon footprint are, the companies that have transparent sustainability practices at their core should continue to fight the good and necessary fight. I think the comparison to how people viewed nutritional facts to begin is a sound one. We need to re-double our efforts to inform and educate but we also need to address consumption habits and consumer attitudes in taking measurable and significant steps toward truly addressing environmental responsibility. Just because a lot of folks don't get it now, does not mean they don't ultimately need to get it.
Just a thought..

And then, restrictions on how much carbon your food can contain. Nevermind we are a carbon based planet; there's no escaping it - enough already.
