My Carbon Emissions for April 2009


I’ve got quite into the idea of publishing my energy use information, partly as a way of keeping tabs on what my big carbon emitting activities are, but mainly because I’m interested in learning how easy (or otherwise) it is to work out. I’ll publish it on the blog every month. If you know better ways of working out the CO2, let me know.

For the month of April 2009:

  • I did 20 days of commuting by train and tube (22 miles each day) = 50.000 kg CO2 (Data source)
  • I drove 373.3 km in the car at 155 g CO2/km = 57.860 kg CO2 (Data source)
  • I took no flights or long-distance trains this month. Yay! = 0 kg CO2 (from Dopplr)
  • And my home electricity usage was 121 kWH = 63.575 kg CO2 (From my Wattson)

So Grand Total = 171.435 kg CO2

Things I’ve left out:

  • Heat and hot water in my flat (this is provided from our onsite CHP and I can’t get monthly data)
  • Food (I don’t know how to measure this)
  • Embedded energy in products I buy (again, I don’t know how to measure this)
  • Electricity and energy in the office (might be able to do this soon)
