However, I DO ride a motorcycle, pumping out far less CO2 than almost any other motorised road vehicle.

Not quite true. http://www.ocf.berkeley.edu/~siah/MiniProjects/MotorcyclePollution.html In urban setting yes, but in rural or highway driving they pump out more CO2 pollution. About 50% more.

Remember less gas != less CO2. Just check your lawn mower.
