He doesn't say that bicycles produce more CO2 than cars, he says that:
Drivers pay road tax to cover the costs of roads, including bike lanes, why shouldn't bikes pay some of this?
You will find that a substantial number of cyclists have a car and already pay road taxes.
Cycling increases your respiration rate so produces more CO2 than not cycling.
This might only be true while cycling. However, because of cycling, my fitness and weight has vastly improved, resulting in a more efficient respiratory system that emits less CO2 during rest time. I spend more than 95% of my time not exercising. I would go as far and say that my overall carbon footprint might have actually been reduced due to my 8 hours or so weekly cycling.
There are quite a few unfit people here in the office that breathe heavily just to walk from their desk to the water cooler. Good thing we have lifts, I can only imagine their CO2 emissions had they used the stairs.
