Okay, so to also summarize for anyone else reading, here's what's going on. The assumptions are:

- Using 261 gal gas/year (which 21.5 gal/month, or e.g. driving 2 × 15 mi/day at 41 mi/gal)

- 1 gal gas = 8.9kg CO₂ (resulting in 2.3 tons of CO₂/year)

In your case that's 15.6 tCO₂/year for flying, vs. 2.3 tCO₂/year for driving.

So, yeah... your flying footprint is 678% more than driving. i.e. you need to fly to work less often than once every 7 months in order for it to beat driving the route you had in mind.

Sorry for the bad news :( but yes, you're very much correct that this makes it even harder for remote work to be good, if you have to fly even twice a year.

Well, he's working a continent away from his office. There are still infinite possibilities for remote work without having to travel 2500 miles for those occasional visits.
