How About this for Saving CO2 Emisions?

This post has nothing whatsoever to do with water except that you might get wet doing what's suggested especially in London.
There's a fascinating website called Walkit from a UK company. Here's how it works...
You decide to go for a walk in London and you want to have a map of the walk ... in the example I used I wanted to walk from The Strand, corner of Fleet St to Fenchurch St Station. Before the map was generated you're asked if you want to take a slower route or a normal (direct) route.
After adding these simple requirements a map and instructions are generated ... see map above with instructions below (on site you get better listed instructions) ... the route is overlayed on the map using a thick blue line.
In addition to the basic map information it tells you distance (2 miles, 3.3 kms) and how long it will take to finish the walk at 3 different speeds ... fast, slow or medium. It even tells you how many calories you will bun up at the different speeds. Not only that it tells you how much CO2 emission you have saved by not taking either a car a taxi or a bus.
Walkit allows you to choose a route with least pollution exposure for London.
