If you want to take a really deep dive... You're not even factoring in an allowance for the fact that JITM relies on parts shipments from all over the world, regardless of where the car is assembled. Guess where the majority of those parts come from globally? You can probably guess...I made a quick 'POMA' calculation myself based on a RoRo the size and tonnage of THEBEN/GLOVIS SPLENDOR burning this amount of bunker fuel on a China-Europe journey, and divided by roughly 4000 cars on board. And I didn't even account for the fact that bunker fuel emissions are immensely more toxic than modern petrol in an ICE.
I appreciate there is probably a much more accurate way of doing this and I welcome any refined calculation method to better sense the carbon footprint of a Tesla arriving on our shores shipping-wise.
Of course, that's why I highlighted that I, myself, have never bought a car that was made on another continent.
Absolutely, I have never even remotely floated the idea that an ICE car would be more efficient, just that currently, our Teslas do come with a much larger footprint than anything built on our continent, and therefore they should accelerate all efforts to shift to a local production to bridge this gap, to avoid this probably 15k to 20k miles required to break-even vs an ICE.
And of course I am not even mentioning the rare earth mining impact of batteries sourcing which would move even further down the break-even point. I believe I've read a study mentioning something like 30k miles, assuming that all your charges are coming from 100% renewable electricity, otherwise it's more like 50k...
These are all stepping stones until we really get cradle to cradle going as something that is adopted by the world on a huge scale. (And a global shipping revolution).
Engineering Explained did an interesting video on this a few years back, and I don't know if his data included shipping, but I think given the sources, it probably did..
