So a car commuter with a 20 mile commute emits 2 tonnes of CO2 per year; a digital nomad without a car commute would need to fly around 20,000 miles a year to get the same amount of carbon emission -- which is the equivalent of two return flights from London to Bangkok, or 10-11 return flights from London to Lisbon.

So they are roughly on the same order of magnitude as a suburban car commute, but could go substantially higher with weekly return flights...

The ones I know travel that much several times a year, which puts them over an order of magnitude above a suburban commuter, at least for travel costs.

So compared to most of the world, who don't have cars to commute, they're multiple orders of magnitude over.

Darn. I had hoped they weren't polluting so much. I hope they enjoy the environments they are helping pollute before they're gone.
