Don't forget the contribution to climate change. It's probably negligible, since the cheating VW cars make up a very small portion of cars worldwide, but it's still worth thinking about, in my opinion.
- femto113 11y agoIt might not be that negligible--in the US alone there are were half million or so diesel VWs sold since 2009--if they are really spewing 40x the limit, then we're talking emissions equivalent to almost 20 million cars that do meet the limit. This is around 1 to 2 years of total new cars sales, or roughly 10% of the active light-duty vehicle fleet in the US.
- MagnumOpus 11y agoThis is not about climate change. The main climate change contributor from emissions is CO2 - which relates 1:1 to fuel consumption (and how could it be otherwise). Fuel consumption is hard to fake and is tested independently all the time. What this is about is particulates and NO and NO2 - which aren't a significant contributor to climate change, but have detrimental effects such as emphysema or bronchitis in humans, acid rain or creation of surface ozone that damages lungs.
