20kg of CO2e

I've been playing with some numbers and have come up with a list of things that all give about the same amount of carbon emissions (approximately 20kg CO2e):
  • 5 days of average Kiwi household power use (100kWh) - if hydropower
  • taking the bus from Auckland to Palmerston North (500km)
  • driving from Auckland to Huntly (100km)
  • 10kg of dry fertiliser (20% nitrogen fertiliser)
  • 80 standard loo rolls
  • a 3L steel saucepan (1kg of saucepan)
  • a pair of cotton undies
  • 3 square metres of wool carpet
  • 2 square metres of vinyl flooring
  • 1.5 square metre of window glass (single glazing)
  • 1/2 a square metre of driveway concrete (10cm deep)
  • a square foot of house (just the shell, typical Kiwi construction)
  • a square foot of solar panel (monocrystalline)
  • 44kg fruit or vegetables grown organically or in New Zealand
  • 33kg conventionally grown imported fruit or vegetables
  • 20L milk
  • 13kg lentils
  • 5kg chicken
  • 2kg cheese
  • 1kg of beef
Certainly brings out how different things have different impacts - and not always in the ways you'd think!
