One question that has been passing through my head for a couple of days is this
What is the carbon footprint of the campaign trail?
With the leaders of the three main political parties racing up and down the country and all the party minions on their local beats, in their planes, tourbuses and cars I wonder what this costs us in environmental terms?
With each party proclaiming their green credentials and seeking to win the green vote, it would be interesting to see which party has actually taken steps to reduce it's own footprint, or is genuinely looking for alternative ways of doing things. I imagine that the difference (if any) between them is very slight.
A google map showing where the party leaders visited is available here (http://www.guardian.co.uk/politics/interactive/2010/apr/06/election-2010-leaders-brown-cameron-clegg), we must draw our own inferences.
