On the Buses

Think all major cities that have congestion charges should channel the money raised into hydrogen buses.

Which is free or very cheap for all users.

  Has any body got any more suggestions for easing the traffic pollution?

Many more big cities are destined to have congestion charges. These charges are supposed to help the environment by reducing the number of  vehicles  in these cities so yes, the money raised should only go on eco-friendly ways to get people around and nothing else. These buses look really good.

I think more park and ride services should exsist. I Designed one for my local city for my geography project. I also think that the buses you use are just as important - maybe the hydrogen Buses, or maybe a few of the Alexander dennis enviro 200 h darts, which is basically the name of a bus which produces 30% less carbon dioxide :)
