Reports

Reports look like this, and generate figures like the ones below that highlight your carbon consumption relative to the average American.

Carbon consumption by category (by label)

Carbon consumption by category (kg Co2/year)

Assumptions in carbon footprint

Electricity:

Electric bill - 11,698 kwh/year = average energy consumption / household.
the U.S. average is 13.27 cents per kilowatt hour (kwh), 0.62 kilogramCO2 / kwh.
11,698 kwh/year * 0.62 kgCO2/kwh = 7,252.76 kg CO2/year.

Flights per year:

Flights per year - average is 2.1 trips per American (if fly).
Assume 0.1304 kgCO2/km for medium-term flights (DEFRA model).
Domestic flights ~2.5-3 hr, 2200km * 0.1304 kgCO2/km * 2.1 trips = 602.448 kg CO2/yr.

Transportation:

Average American drives around 15,000 per year (assume this is all forms of ground transport).
Fuel efficiency on car - assume 30 mpg on road car now.
0.960 pounds = 0.435 kg CO2 per mile (driving) * 15,000 miles/year = 6,525.0 kg CO2 / year.
0.657 pounds = 0.298 kg of CO2 per mile - 50% public transport, 50% single auto * 15,000 miles/year = 4470.0 kg CO2 /year.
0.354 pounds = 0.161 kg of CO2 per mile (public transportation) * 15,000 miles / year = 2,415.0 kg CO2 / year.

Uber trips:

(14 uber million trips / day * 0.50)9 / 325 million people (USA) * 365 days / year = 7.86 rides/person in the USA (assumes 50% of all uber rides are in the USA).
Average ride length = 6 miles/trip * 7.86 trips / person / year * 0.960 kgCo2/mile = 45.27 kg Co2/uber rider/year.

Food choices / nutrition:

1.7 US tons = 1,542.21406 kilograms of CO2/year - vegetarian.
2.5 US tons = 2,267.96185 kilograms of CO2/year - average.
3.3 US tons = 2,993.70964 kilograms of CO2/year - meat lover.

Amazon supply chain:

0.1289 kg CO2e per dollar (USD).
3,300,000 boxes/day13 * 365 days/year / 325,000,000 Americans = 3.70 boxes/American.
3.70 boxes/year * $47 / box = ~$173.90/year * 0.1289 kg / $1 USD= 22.41 kg CO2/year.
