Again, you miss the point. There are no cities anywhere near Edinburgh. The closest is Glasgow, and frankly, the chances of a company relocating to Glasgow on the basis of the marginal increase in inconvenience of an LEZ is close to, if not actually equal to zero.I'm not a sweaty, so have no horse in this race.
Some firms will doubtless take their business elsewhere. Do I care where they go, no I don't. Neither does Edinburgh City Council it would seem. Their loss and some small nearby town's gain.
You only have to look at the number of cities that have vacant office space that, post-covid and the new normal of working from home, will never get tenants, further damaging the economy of city centres. A CAZ just makes a city centre even less attractive to a firm. Why have a big expensive city centre office/shop that you/your customer then have to pay the CAZ charge to access, when you can rent an office/shop elsewhere with no CAZ and possibly cheaper rates.
I am not in favour of this by any means, and my vehicle would be affected being a 2014 plate diesel, but I can see why they think that they will not lose out substantially with this.
