With COVID lifting we're back in traveling mode this summer; I ran some quick calculations while watching tennis this am on CO2 emissions per "family mile" (to move all five of us) from our home base in San Diego; thought I'd share if anyone's curious.
Assumptions:
0.39 lbs CO2e / passenger mile by air
20 mpg for our Odyssey minivan
2.2 statute mpg for our CHB41 trawler
Outputs:
A family trip to Europe (6000mi) by air is about equivalent to taking the boat all the way to the Pacific NW
Our typical summer 6 week cruise up to Santa Barbara and around the channel islands is about equivalent to a cross-country road trip in the Odyssey or air travel to my brother-in-law in St Paul, MN.
A trip to Catalina and back is equivalent to air travel to San Francisco
Conclusions:
In the real world for most people, air travel CO2 emissions are astonishingly high relative to trawler emissions given the frequency and length of air travel vs boat travel. It's different if you're not multiplying the air miles by a family of five of course. But if you're on your own or as a couple, it's a lot easier travel by air so you're likely to do it more.
