French press and espresso, IMO, taste far better than pourover with paper. I also prefer metal mesh with pourover, as it allows for more of the oils to seep into the carafe. But it’s just a matter of opinion. :)

Remember the whole trail of paper carbon impacts! Trees get cut to make them. Then they have to be cut/manufactured in a big factory, which uses energy. Then shipped to your stores, using gasoline. Finally you throw them away where they sit in a landfill (the most negligible part).

Though to be clear, you’re still correct that the carbon impact is negligible compared to like… big oil and cow farms. So you’re right on that front. :) Worrying about the negligible is not worth anyones time when there is an elephant in the room.
