If it's any consolation OP I think the message is getting out.
5 years ago I was your worst nightmare. New cars (DH and I) every 3 years (neither economical re-petrol - actually the reverse).
Minimal re-cycling.
3 holidays abroad a year (flights).
Lover of cling film, and anything disposable.
Fast forward to today.....
The cars on the drive are 4/5 years old and we have no plans to replace them. When we do it will be to buy an electric car (probably a Tesla).
We've been (as a family) on on international holiday (flights) this year and though have other holidays planned we are travelling by train/car.
I've overhauled our waste management. Re-cycling is a big thing in our house now.
I was overjoyed when a zero waste shop opened in the next village, where I can take my reusable containers. So much so that I spoke to the butcher in my village and he's agreed to do the same (with a big notice) and it's lovely to see people queuing up with their own food containers.
That said, we are also cutting down on meat generally. I'm not going to pretend we'll ever be a veggie only family but we no longer have meat every day (4 out of 7 atm).
Cling film is banned from the house. I use wax wraps.
Disposable wipes are banned. I have a mound of washable flannels.
We use shampoo bars/soap.
Still a long way to go, but unlike some posters I do think if we all make changes it makes a difference.
They don't have to be life changing but every little really helps.
If I can be "changed" from my "previous" lifestyle and not feel shortchanged by it, then anyone can
