I found myself with a bunch of air miles, and looked into how to use them. Then I discovered that the cost of my family's carbon footprint is quite low:
- 52 tons of CO2e / year
- offset for $426 or 60k air miles ($8.23/tonne)
What is the value of a mile?
see a sloth $195 / 31,000 = 0.0063 (bad rate) cirq du soliel gift card $200 / 27,000 = 0.0074 (good rate) most gift cards $25 / 3,500 = 0.0071 (normal rate) most gift cards $50 / 7,000 = 0.0071 (normal rate) most gift cards $100 / 14,000 = 0.0071 (normal rate) most gift cards $150 / 21,000 = 0.0071 (normal rate) most gift cards $200 / 28,000 = 0.0071 (normal rate) most gift cards $250 / 35,000 = 0.0071 (normal rate) most gift cards $500 / 70,000 = 0.0071 (normal rate)
So lets say that you get 0.0071 $/mile
60k * 0.0071 = $426
What is the cost of offsets?
With 15,000 air miles you can buy 13 tonnes of GHG offsets through offsetters.ca which (at 0.0071) is $8.23/tonne. That appears to be the same product that's sold directly at $20/tonne. It's not clear what accounts for the cost difference, or what is the quality of the offset. I.e. planting trees for later harvest doesn't actually offset the release of fossil carbon.
A 2010 press release listed 7,500 Aeroplan Miles for 3.2 tonnes with a 20% match from aeroplan. It's now listed as 7,500 Aeroplan Miles for 6.5 tonnes. Another press release says the offsetters GHG through aeroplan is a collection of Gold Standard projects, so it appears to be the $20/tonne product.
How much GHG does my family's lifestyle cause?
From the Guardian in 2008: "The annual carbon footprint of the average Briton is around 10 tonnes".
From NRC Canada in 2019: a not very helpful equivalency calculator.
If it can be believed, carbonfootprint.com has a helpful calculator. Here's my calculation.
Canada Ontario Jan-Dec 2019 Electricity: hydroottawa.com says 6844 kWh in 2019 becomes 0.14 metric tons Natural Gas enbridgegas.com says 1997 m3 in 2019 businessenergy.com says 1997 m3 = 22237 kWh becomes 4.09 metric tons Travel: 3 ppl YOW-MBJ becomes 2.48 metric tons 20000 km on 2011 subaru impreza becomes 4.57 metric tons 10000 km on 2016 mini cooper becomes 1.51 metric tons 2 x 5km x 12months = 120km uber becomes 0.02 metric tons Other: Food and drink = 7.97 metric tons Everything else = 24.94 metric tons Total: 45.72 metric tons of CO2e
If that calculator can be believed, then energy and transport account for less then half our GHG impact. The dominant problem is consumption in general.
