860 miles by car
So about 0.272 tonnes of CO2e per year per https://climate.mit.edu/ask-mit/how-much-ton-carbon-dioxide ?
Of a total of about "2.1 tonnes per person annual emissions budget necessary by 2050 to meet the 2 °C climate target (Girod et al 2014)" per https://iopscience.iop.org/article/10.1088/1748-9326/aa7541#erlaa7541r22 (Girod 2014 seems to be paywalled).
- 0 of 58.6 tonnes of CO2e/year because I'm childfree,
- 0 of 2.4 tonnes since I'm carfree (never bought a car, I don't even have a driver's license),
- 0 of 1.6 tonnes per flight (tho I did fly once in my life, more than a decade ago),
- 1.47 for electricity because I don't buy ethical green energy,
- ? because I'm vegan, so that reduces my footprint a lot, but I'm not sure what to deduct the 0.82 from,
- ? because of cold washing laundry, but I don't know what to deduct the 0.25 from,
- 0.272 tonnes for using a computer to access the internet,
- ? for several other things tho at an order of magnitude lower than the big ticket items.
That total seems below the 2.1 tonnes of CO2e per year sustainable target per person by 2050.
There is a difference between sustainable, non-sustainable, and catastrophically unsustainable; and it's an important difference. Having a locavore diet is very easy where I live, except for vitamin B12 supplements which are not locally sourced or made. I don't know what you mean by "survive the winter", it's not an issue where I live. I only use salt and turmeric when I prepare food - tho some processed food I buy contains other spices.
