I guess the fundamental problem is that there is money in showing webpages for the sake of it, due to ads. It is like litter. Paper ads are somewhat limited due to consumer complaining about having their mailboxes filled with them and someone has to go there and put it in and can't avoid a homeowner guarding the mailbox if they would force the issue. Using e.g. uBlock Origin might be the most impact for no effort environmentally friendly thing you could possibly do.
