In my recent blog post Green travel emits 60% less CO2 I calculated that by travelling by bike and train on my sabbatical I saved more than half the carbon I would have emitted if I used a car. I has used an online calculator and chose the small car option (and the emissions attributed to that small car per mile)’.
Last week we had to by a new tax disk and thankfully the DVLA sends a reminder. It states on the paper details of our car including Engine Capacity/CO2. For our car this is 151g/km. Now as our car is getting on for 10 years old I guess that it is now less efficient than when it was made but its the best information we have so I’ll use that.
If I travelled to all the reserves by car I would have driven 843 miles or 1357km. If I had used my car it would have pumped out a total of 205kg CO2 – more than the ‘small car’ option used by the estimator earlier. So this means that compared to travelling in my own car I emitted 67% or two thirds less CO2 through my green travel.
