Why not walk it?

Sometimes the greenest ideas don't come from a desire to improve sustainability. Take walkit.com, the UK's first walking route planner. According to a profile in BT's customer magazine, founder Jamie Wallace was driven more by the desire to save time. He wanted to prove to his colleagues that walking to meetings in central London could be quicker than using any other form of transport. Of course, he caught the zeitgeist (and the London congestion charge!) and walkit.com is now popular with those who want to cut the carbon - it even calculates how much carbon you've saved.

He's busy adding new cities to the site but while you're waiting from walkit to get round to including your own city, you might find that adding the Co-Pilot application to your PDA is a worthwhile alternative. It has a walking mode as well as the normal route planning and driver's satnav features and can even be used to avoid buying printed maps for countryside walks.
Finally, if you do decide to walk it, tell Green Thing. Walking was its first ever green thing, in October 2007.
