That said, my understanding of the fossil fuel industry is that consumer automobiles only make up some small fraction of carbon emissions. I don't have a source (and I would love to see one), but I was under the impression that the majority of carbon in missions were due to commercial shipping and electricity generation. Nobody was out in the streets demanding cheaper electricity and cheaper products on Walmart shelves. Industry simply provided those things. You basically can't blame consumers for shifting consumption towards cheaper goods, that is why externalities are externalities.
Also consider this erratum from my previous post: how much ExxonMobil shareholder equity and executive compensation over the last 20 years can be attributed to lack of political will to action on carbon emissions and climate change? Surely that number is big enough to at least make a dent in the relocation task at hand.
