You have to consider the significantly higher weight of glass increasing carbon emissions from transportation.
If the transportation was electrical renewable sourced this wouldn’t be a factor.
their production is far more energy-efficient (glass production is done at temps of 1400-1600 °C or 2500-3000 °F while plastics use temperatures from 160-300 °C or 320-600 °F)
If manufacturing was electrical renewable sourced this wouldn’t be a factor.
I don’t want micro plastics in my nutsack. I don’t care that it’ll be a long time before we get there. We should start getting there now. I don’t want to hear perfectionist fallacy arguments about why I should be happy to have plastics swimming around with my sperm.

It used to be done a lot more before and some places still do it in Europe. You return the glass bottle intact, they reuse it as is. Only carbon spent is in transporting it.

Well, you also have to clean them which I assume also uses energy. And they need to be fulfilling “food-grade” cleaning requirements since you want to drink out of them, so that’s probably more energy needed than a simple wash in soap.

This is done regardless of the source of the glass. IE fresh or reused glass gets the same cleaning treatment.

It’s done less and less because recycling plastic bottles is better.

Yes (I actually live in Europe), but it cannot be reused indefinitely and needs to be recycled after about 50 uses (that’s why I mentioned the whole life cycle of a bottle). Also, glass breaks.
