Volkswagen scandal: Unintended Consequence from Climate Change Politics

Prolific science author Matt Ridley explains why the Volkswagen scandal represents the unintended consequence from the politicization of Europe's auto industry due to climate change politics. [bold mine]

The Volkswagen testing scandal exposes rotten corruption at the core of regulation. Far from ushering in a brave new world of cleaner air, the technologies adopted by European car makers, driven by policy makers in Brussels, have been killing thousands of people a year through an obsession with lowering emissions of harmless carbon dioxide, at the expense of creating higher emissions of harmful nitrogen oxides. 

There is a lesson here that goes much wider than the car industry, the clean-air debate and even the regulation of business. The scandal is a symptom of the political world’s obsession with directing and commanding change, rather than encouraging it to evolve.

The great European switch to diesel engines was a top-down decision as a direct result of exaggerated fears about climate change. Convinced that the climate was about to warm rapidly, and extreme weather was about to get much worse, European governments signed the Kyoto protocol in 1997 and committed to reducing emissions of carbon dioxide in the hope that this would help. In the event, the global temperature stopped rising for 18 years, while droughts, floods and storms also showed no increase.

But in 1998, urged on by EU transport commissioner Neil Kinnock, welcomed by environment secretary John Prescott and acted on by chancellor Gordon Brown, Britain happily signed up to an EU agreement with car makers that they would cut carbon dioxide emissions by 25% over ten years. This suited German car makers, specialists in Rudolf Diesel’s engine design, because diesel engines have 15% lower CO2 emissions than petrol engines.

The EU agreement was “practically an order to switch to diesel”, says one clean-air campaigner. As subjects of Brussels, Britain obediently lowered tax on diesel cars, despite knowing that they produce four times as much nitrogen oxides as petrol, and 20 times as many particulates, both bad for human lungs.

The story is almost a textbook case of why top-down regulation can be so dangerous. It lets single-issue pressure groups set targets with no thought to collateral damage, and imposes regulation that inevitably gets captured by those with a vested interest. Regulation also often stifles innovation. We may never know just how much innovation in cleaner petrol engines was prevented.

I can't resist a good quote when I see one...more from Mr. Ridley 

Dirigisme often does real harm. Telling people to eat less fat, based on a few dodgy studies in the 1950s that purported to find a link to heart disease, has probably worsened obesity by encouraging high-carbohydrate food. Discouraging electronic cigarettes, in the demonstrably wrong belief that they increased rather the decreased smoking, is slowing progress in the fight against smoking. Deliberately mandating that banks and government-sponsored enterprises (Fannie Mae and Freddie Mac) make or purchase sub-prime loans, as Bill Clinton and George Bush both did as a way of trying to raise home ownership among ethnic minorities, was a major contributor to the crash of 2008.

Equating order with control retains a powerful intuitive appeal, as the American social theorist Brink Lindsey has pointed out: ‘Despite the obvious successes of unplanned markets, despite the spectacular rise of the Internet’s decentralized order, and despite the well-publicized new science of “complexity” and its study of self-organizing systems, it is still widely assumed that the only alternative to central authority is chaos.’

That's because economic and political myths are popularized by media, political agents and their cronies.
