Given at that the eyes of the world are looking to the Climate Change conference in Copenhagen for answers to the biggest environmental challenge of our time. I thought it would be a good day to ask, How green is your daily journey? To help you work out if you are doing you bit, I have found this handy Travel footprint calculator from travelfootprint.org.

If you would like to know more about the methodology used to assess the impact of your journey, see here.   For what it is worth, my journey today resulted in the emission of approximately   46.4 g of CO2. The emission due to my writing of this post and your reading it, are another matter.
