Playing around on a Friday afternoon:
London Rome: 234kg CO2
London New York: 986kg CO2
(But that does not include a ~1.8 "effective" multiplier due to releasing CO2 high in the atmosphere)
The weight of CO2 is greater than the weight of fuel due to adding 02 from the atmosphere.
1 gallon Diesel: 10.17kg CO2
1 gallon Gasoline: 8.63kg CO2
15,000 miles per year / 20mpg = 750 gallons per year
750 gallons per year * 8.63kg = 6,472kg CO2
Massachusetts average heating oil usage:
719 gallons x 10.17 kg/gal = 7312kg CO2
Average household size, 2018: 2.53
My house, Oct-May heating season actual usage: 4,168kWh above baseline most of which can safely assumed to be the air source heat pump.
EIA Statistics: 2017 Connecticut Electricity production produces 501lbs CO2 /MWh
(501 / 2.2) / 1000kWh
227kg / 1000kWh
.227kg / kWh
946kg...which is 1/8th the average heating carbon footprint.
Polypropylene needs at least 11 re-uses (and are largely imported due to the extra labor of weaving; I'm not sure that the labor + transport was accounted for) and a cotton bag needs 135 re-uses. I suspect nylon would be in-between.
At 0.02kg CO2, a disposable plastic bag there are 431 plastic bags per gallon of gasoline or 300' of travel in the average American car.
