This also means two thirds of emissions are not due to vehicular emissions. Let’s tackle that first, more bang for the buck?
Also - does that per capita figure include cargo? If so, how much? Does it matter if random individual takes personal Responsibility and stops driving when all those long haul trucks will still be on the road?
My point is that in terms of personal responsibility nothing comes remotely close to driving but a vanishingly small proportion of people are willing to consider this.
