If they are just sold on and continue to be used when they fail emissions testing, what is the point of emissions testing at all? The vehicles will just end up in countries that don't care, and emissions will rapidly get worse as they will get minimal maintenance and probably lower quality fuel.

- vkou 5y agoIf there was no emissions testing to begin with, these trucks would be designed to pollute for their entire service life, instead of just the last 20-40% of it. Also, I don't want pollution in my town. The tradeoff of 'tiny reduction in cost of transportation for way more air pollution' is not worth it for me. If some other town on the other side of the planet thinks that trade-off is worth it, that's their decision to make. The effect of this kind of pollution, unlike GHG emissions, is largely localized.

Yes it sucks about the countries where they end up but it's the responability of the local governments to care what level is acceptable and what not. And often governments have to balance the need to stimulate local economy (by affording to buy cheaper used machines) vs the public health concerns.
