@asgardius that's quite a price tag. Have you heard of @murena phones using e/OS? https://murena.com/products/smartphones/
They even have a Fairphone murena phone. But if you really care about the environment then reuse your phone and install eos on it. There are eos installers for some phones and for many other phones you need a bit more technical knowledge (i have changed it on Samsung Galaxy S5 but I am struggling with Moto x4 locked bootloader)
