g vil vekja athygli gri grein vefsunni Vox, eftir Brad Plumer. Fyrirsgnin er:Europe's love affair with diesel cars has been a disaster

greininni er m.a. rakin run og sta ess a dsilblar uru svo vinslir og segir m.a.:

"But starting in the 1980s, French and German automakers began showing more interest in developing diesel cars. The reasons why have always been a little murky, although Cames and Helmers suggest it traces back to the OPEC oil crises of the 1970s. After global crude prices spiked, France decided to swear off using diesel for electricity and built a fleet of nuclear plants. Germany, similarly, switched from oil to natural gas for heating. When the crisis subsided, Europe's refiners were still producing lots of diesel with no buyers. So governments began urging automakers like Peugeot to look into diesel-powered vehicles.

...

At the time, there were lots of different paths Europe's automakers could have taken to green itself. They could've pursued direct injection technology for gasoline vehicles, making those engines more fuel-efficient. They could've ramped up development of hybrid-electric cars, as Toyota was doing in Japan. But European companies like Peugeot and Volkswagen and BMW had already been making big investments in diesel, and they wanted a climate policy that would help those bets to pay off.

Europe's policymakers obliged. The EU agreed to a voluntary CO2 target for vehicles that was largely in line with what diesel technology could meet. As researcher Sarah Keay-Bright later noted, these standards were crafted so as not to force Europe's automakers to develop hybrids, electric vehicles, or other advanced powertrains.

Meanwhile, European nations including Britain, France, Germany, Italy, Spain, and Austria had been cutting taxes on diesel car purchases and diesel fuel to promote sales, all in the name of thwarting climate change. Diesel sales soared. Back in 1990, just 10 percent of new car registrations in Europe had run on diesel. By 2011, that had climbed to nearly 60 percent."

Og n er svo komi segir greinni a dsilblar eru ornir a alvarlegu heilsufarsvandamli:

"Diesel engines do have one notable pitfall. They may be more fuel-efficient and emit less CO2 than gasoline engines, but they also tend to emit higher levels of other nasty air pollutants, including soot, particulates, and nitrogen oxides (NOx). Heavy exposure to these pollutants can exacerbate heart and lung disease, trigger asthma attacks, and even cause premature death.

This was largely known back in the 1990s. Europe's policymakers simply considered the trade-off acceptable. "At the time, the prevailing belief was that climate change was the really hard problem and should be the priority, whereas we'd had experience improving air quality, so everyone assumed we could easily fix that issue later," explains Martin Williams, an air pollution researcher at King's College London who previously worked for Britain's environmental agency.

That assumption turned out to be wrong. When European regulators later moved to clamp down on NOx and other conventional air pollution from diesel vehicles, they failed badly."

Og niurstaan greininni er einnig a allt "dsilfri" hafi ekkert gert til a draga r "grurhsahrifum".:

"If Europe's diesel surge over the last 20 years had helped mitigate climate change, then maybe (just maybe) you could argue that all this extra air pollution was worth it. Except here's a depressing plot twist: The climate benefits appear to have been negligible, at least so far.

In their 2013 paper, Cames and Helmers argued that Europe may well be worse off today, from a global warming perspective, than it would have been if automakers had just focused on improving gasoline-powered cars all along. And it's arguably much worse off than it would have been if automakers had started investing in hybrid-electric technology back in the 1990s.

The authors start with the chart below, showing that Europe's diesel cars may have once had a sizable CO2 advantage over traditional gasoline vehicles. But today that gap has narrowed considerably, asvarious technological advances have made modern gasoline engines nearly as efficient as diesel cars:"

a er v ef til vill ekki a stulausu a greinarhfundur varar vi opinberri neyslustringu essum efnum og hvetur frekar til ess a hi opinbera setji markmi, sem markasfl keppi um a leysa:

"So one approach here might be to pursue technology-neutral policies focused on preferred outcomes say, tightly enforced standards that require lower emissions rather than favoring specific industries and technologies just because they happen to seem promising at that moment in time.

This conundrum is likely to come up again and again. For years, governments have been laying down big bets on emerging clean energy technologies. France did it with nuclear power in the 1970s and '80s. Germany did it with wind and solar power in the 2000s, through feed-in tariffs. The United States has done it with corn ethanol in the past decade.

Done right, this sort of government support can be valuable, helping useful new energy options break into the mainstream against entrenched competition. But there's also a huge risk that governments will end up gambling on badly flawed technologies that then become the entrenched competition and prove impossible to get rid of. The US arguably made that mistake with ethanol, which has had unintended ripple effects on the food supply and deforestation that are proving politically difficult to untangle. The drive for diesel looks like it belongs in that category, too. It's not a story we'd like to keep repeating."
