John, to be momentarily pedantic, when you burn hydrocarbons, you get mostly H20 and C02. The carbon has to go somewhere, you can't turn it into water without a nuclear reaction. Water is where the hydrogen goes. Emission controls can't do anything about CO2, what they control is emissions of incompletely burned hydrocarbons (which includes carbon monoxide, CO) and nitrogen oxides. Modern emission controls also help fuel efficiency a lot, since complete combustion is efficient combustion. CO2 isn't considered a component of atmospheric pollution, in terms of smog and stuff like that.
As for the political cheap shot at the end, well, as you said, you're not a scientist, your knowledge of other areas might be a little incomplete also. |
