CO or CO2, that is the question...

What would happen if we banned Catalytic Converters?

As I understand it (from wiki), for a cat to run they need the engine to run fuel rich. They then turn CO + O2 into CO2 and unburnt hydrocarbons into CO2 + water.

When we're failing to curb our CO2 emissions this sounds like a bad idea (especially when it means reduced fuel efficiency), but I assume there must be a logical reason to do it.

What would happen to the environment (both local and global) if we decided to accept the CO hit instead of the CO2 one?

Well it won't do shit environmentally. In the grand scheme of greenhouse warming potential and toxicity to the average human, CO2 is very much the lesser of all possible evils.

You are dumb. CO is Carbon Monoxide, which is a colorless, odorless, tasteless yet highly toxic gas. CO2 is Carbon Dioxide, which is the byproduct of all breathing done by every animal on earth. Read a book.

CO, apart from being toxic, also indirectly contributes to the greenhouse effect.

Response by poster: parmanparman - thanks for your expert input.

Yeah, I know that carbon monoxide kills. As does water. And sugar. I know that carbon dioxide comes out of my mouth. I also know that carbon dioxide is a greenhouse gas.

What I don't know is how the comparable quantities of the different carbon molecules effect us and our environment.

Now stop being a cock and leave the grown ups to play.

Aside from being poisonous, CO eventually turns into CO2 in the atmosphere, plus it is a greenhouse gas itself, plus it apparently causes increased levels of ground-level ozone, another poisonous gas.

In addition, catalytic converters reduce NOx emissions. NOx is also a greenhouse gas and is a major component of acid rain.

If you want to think of a world without catalytic converters, think LA in the 70s.
