I like the idea of compressed-air cars for city use. It would
help a lot if there are air-filling stations for this type of
vehicle, which uses only air expelled at high pressure (or a hybrid
engine) for locomotion. Britain sets out footprint for low carbon

I've found a website that looks pretty good:
www.carboncreditz.org It lets you earn points just by doing online
shopping as usual, although you have to go via their website first.
You can then spend creditz on their online shop or you can offset
with a registered project. It is a really good website, it allows
you to calculate your carbon footprint - I was really shocked with
mine.
