As stated in my post, I wasn't sure of the correct terminology.
I'm not sure
any car (ICE
or EV) - indeed any manufactured goods,
ever pay off their manufacturing CO2. You're not alone in using that terminology, but I think it's actually technically wrong. So unless someone can show me how any manufactured product "eats" CO2, we just have to accept that once something is made, the CO2 emissions used in making it, are out there... forever...
Keeping an older car on the road, especially with a low annual mileage, means those owners are not contributing to the energy & emissions produced in the manufacture of a new car, be it EV or ICE.
And I agree completely with that. It's absolutely true. If I was doing very few miles a year, in a rural area, (and particularly if I didn't have that many more motoring years left in me), I'd keep whatever ICE I was in too. Indeed, my parents are currently running a 2001 diesel Freelander, which doesn't even have a DPF. There's little sense in them getting an EV for the miles they do. I don't know whether they'll give up driving before the Freelander gives up the ghost, but it will be a close-run thing.
I'll even go further and say that like-for-like, the manufacturing CO2 emissions of an EV are
higher than the equivalent ICE! However, when you consider the total
lifetime CO2 emissions of each, the EV is significantly better. Depending on the country they're operated in, they'll overtake the ICE between about 20,00 and 50,000 miles, by which I mean, their total CO2 will be about the same, and thereafter, they just get better and better.
The other factor to consider, is, I feel, that although the
current owner of an ICE might do very few miles, the current owner may not be the
last owner. On average, cars in the UK currently live about 15 years. If, (as I do), you cover a big annual mileage, it makes more sense to get an EV than if you just do a few thousand miles a year. But of course, nobody is saying you have to scrap your ICE. We just need to stop building new ones, and let the old ones get to the end of their working lives. That will take a long time. I'm not even 60 yet, and I expect to see some ICEs still on the road, by the time I go to my grave.
Whether or not I'm correct in that belief I'm sure my comment will cut no ice (not ICE) with the pro. EV brigade & to be honest I'm not bothered.
As you can see, you were wrong there...
If the world's current conflicts escalate, squabbling over whose cars 'generate the most emissions' will be the very least of our worries
There are always reasons to put off doing the right thing. Yes, if the conflicts escalate, that might wipe us out before the effects of climate change get the chance. Likewise, if the earth gets hit by a big enough meteor. In fact, they're also great reasons to put off getting fit, losing weight, finding that cure for cancer or, indeed, achieving anything at all in life. However, just on the off chance that the current conflicts
don't escalate and wipe out humanity (and considering we've been squabbling for at least the last 20,000 years, I reckon I'm on a pretty safe wicket here), We'e probably as well carrying on trying to solve the problems...
