I would very much approve a food tax on the externalizes, determined by a review process per product if the seller request it. It would however not be as simple that plant-based food would just be cheaper. Every kind of food type has a spectrum of climate impact, depending on multiple factors like farming method, transport, and local factors. A hunter shooting down an overpopulated flock of wild boars is going to have a distinct different climate impact than a pig farmer in a industry farm. Same for crop rotating farm that don't use fertilizers or pesticides vs one that massively contribute to eutrophication, burn down forests to make room, and leaves a desert behind. A tax would at first fix the competition between similar products that only differ in the climate impact. Secondarily it would encourage locally over imported. And third it would make most plant-based food cheaper vs most meat. It would also add a huge tax on factory farmed meat and encourage farmers to use slower and much less harmful practices when raising animals.
