Forests that we don't cut down is called reservations.

In Sweden there is a law that states that any forest cut down must be replanted unless used for farming or new buildings. I also recall Norawy having the similar law. If we counted that as carbon removal, we would have a massive carbon net negative from this pretty old law.

The law is not a carbon removal strategy. It simply maintain current biomass over time.

That's right. If you want to sequester more carbon, you have to create more forest.
