How much carbon dioxide is produced by burning gasoline ...

I try to keep my energy management efficient. That's about the extent of management. I also plant lots of succulent greenery. I make a rather poor example for hypocrisy. I live in Mexico. I drive in Mexico. However when I go to Califraudnia I get my car tested for emissions. A no certificate test does not cost much and the return in maintaining excellent fuel mileage more than makes up for the cost of the occasional test.

So "PFFFTTHHHHHH!"
