Yes that's a nice summary. It's good to see that some of steps have already been taken (led instead of incandescent) and that at that time photovoltaic technologies weren't viable yet thus not mentioned in the video.
Also I like the irony of showing Volkswagen cars when mentioning efforts from the E.U. to reduce car emissions :)
- adrianN 9y agoIt is my understanding that with internal combustion engines there is a trade-off between NOx and CO2. The hotter you burn, the more efficient the engine, but you also create more NOx. Volkswagen chose to tune their engines for fuel consumption, reducing GHGs, but tried to cheat their way around the illegally increased NOx.
- libeclipse 9y agoIsn't that the whole point of the catalytic converter?
- adrianN 9y agoFor Diesel engines you typically use Ammonia ("AdBlue") to get rid of NOx. Gasoline engines can use three-way catalytic converters.
