But in a roundabout way there is a definite link.
In the fairy-tale land where the oceans are going to boil, the rain forests turn to desert, and humans all perish miserably, there is a distinct and earnest movement afoot to remove the most viable technologies for transporting, well, everything, based in the earnest belief in this wild fantasy that this will somehow cause an end to natural and cyclical processes over which humans have no control and set the planet's thermostat at some ideal temperature, as if there was a paragraph on that in the owner's manual.
But by blaming the wrong factors for the weather, and skewing the data which exist, these folks have justified declaring war on the very fuels which transport every item not produced in their back yards, and claim that this will cause their urban heat islands to cool, along with those produced by the sunlight hitting vast arrays which absorb that energy and convert a fraction of it to electricity, which will power the world (of course), once they get a long enough extension cord.
All that 'war' is expensive, though, and cost of meeting the moving goalposts of compliance with its ever-increasing and arbitrary restrictions (not to mention the patent inefficiencies and unreliability of the replacement systems) has, in fact, increased the cost of transporting virtually anything anywhere.
That cost, of course, is borne by the consumer, who pays higher prices for (see above) well, everything. In terms of material goods per unit of currency, that means it takes more units of currency to purchase any given amount of those material goods, whatever they are.
At some point, 'sustainable' isn't, if for no more reason than it costs too bloody much.
And there is your link to economics, in an organically grown, cage free, free range, sustainable nutshell.
