Who was tha bloke in the US government a few years back who was advocating that the world should switch to Hydrogen power ? He was appointed as head of some scientific body. True, hydrogen can be used as a non-polluting fuel which simply leaves behind water as a by-product. And also true, there is loads of hydrogen available in water which can be extracted. However he obviously had no knowledge of the laws of thermodynamics not to realise that it MUST take more energy to extract the hydrogen from water than you get from using it as fuel.
Bah, could have been an amusing story if I remembered the details

Cars account for a ridiculously low amount of the total pollution belched into the air. Making a car produces more pollution than running it its entire life.

Car pollution accounts for 20% of the overall atmospheric pollution.

I think we need to clarify things, because "pollution" and "greenhouse gases" (or "atmospheric pollution") for example are two different things.
In terms of air quality, the word "pollution" generally applies to toxins or particles, whereas a greenhouse gas is something like carbon dioxide, which is not really a "pollutant" (otherwise you pollute the atrmosphere every time you exhale).
