In the battle against global warming it is tradition that popular media outlets tiptoe around the unintended consequences of the battle. But with the rolling Volkswagen debacle the storyline has been so irresistible journalists and copy-writers have not been able to help explaining. How global warming caused CO2 to be a pollutant, led VW and European car manufacturers to turn to diesel, how diesel made other potent pollutants, and finally led Volkswagen to sell its soul.
But there is an undiscussed link: the train of thought behind the EU push for diesel is the same as the ecomodernists. Behind the thinking of both is the fiction that via a complex meshwork of regulation and ‘innovation’, the impossible would become possible. The logic of the EU in encouraging diesel was that it released less CO2 and that the resulting pollution could be cleaned up by technology. Except the cleanup leads to increased cost, reduced engine power, and as in the case of Volkswagen, cheating.
It is inescapable that if you take a hydrocarbon fuel internal combustion system and strangle the exhaust, either to control CO2 or pollutants, you will lose power. This loss of power will feed back in any number of different routes to defeat the original objective. In the words of Emerson, when it comes to energy use it is ‘best to pay scot and lot as you go along’.
If Volkswagen had put a fraction of the ingenuity that went into its supposed defeat devices into questioning the basis for the CO2 rule it tried to rigorously adhere to, it wouldn’t have found itself in the pickle it is currently in.
