What I DO count: planes, trains, automobiles and natural gas home heating.
What I do NOT count: electricity, as not only is Seattle City Light, powered by 93% renewable wind ,bio-as and hydro-power, but I also have ownership in the Seattle Community Solar program, which kicks back a certain percentage of power-and money-every year. I also had, until July 20018, a solar/electric hot water system on my actual house that, unfortunately, was damaged beyond repair during some roofing work in summer of 2018. I now have a hybrid electric-heat pump hot water system, in preparation for getting solar panels on my roof next year,
I also do NOT count my food choices (though I should) as I have not figured out a way to accurately calculate my food footprint. So far, all the food footprint calculators either over-estimate or under-estimate my meat consumption. I realize I should quit meat, and though I have cut way down, I haven't kicked the habit.
Lastly, I do NOT count the embedded carbon of anything- I have no idea how to even begin that one,
So, for 2018:
Airtravel: 6450 lbs.
Trains: 0 lbs
Automobiles: 738 lbs. (I drive electric cars 100% at home- the gas is from travel car rentals)
Nat Gas: 151 lbs.
Total: 7339.4 ( 7.3 metric tons of carbon dioxide)
This is 35% of what the average American produces which is 20.5 metric tons CO2-equivalent per person. (University of Michigan) (4.7 metric tons of that is from cars alone. (EPA)
If I has made made no plane trips in 2018, my carbon output would have been 889 lbs. Wow.
(Until you factor in meat, clothes, water, etc,)
So- while in comparison to 2010 and 2014, 2018 for me sucks as far as output goes, I still made less over all carbon due to less plane travel (no international flights), though more gas rental car travel negated some of that.
HOW DEB DOES THE MATH:
(I forget where I got this formula I will update post when I find it again)
Short haul <727.45 miles 0.64 lbs/mile
Med haul <2575 miles 0.44 lbs/mile
Long haul >2575 miles 0.39lbs/mile
1 gallon of gasoline = 19.4 pounds of C02
1 therm= 11.7 pounds of C0
1 kWh in Seattle= 0 pounds of CO2
