The half-life of Apple kit is so high, they are arguably a lot more sustainable than their repairable PC counterparts.
Apple laptops I have that boot include a 2007 iBook (my folks used it until this Summer and then bank websites would stop working with the Chrome browser they could get working on it), which I'll be putting a BSD or Linux distro on over Christmas, a 2012 Intel MBP that has Linux on it and a couple of 2015-2017 era MBPs that I inherited via one means or another.
I'm typing this on an M4 MacBook Air I picked up cheap during Black Friday sales. I fully expect it to still be functional in 10 years.
I don't think I've ever had a PC laptop last close to that.
