There's a ton of carbon sequestered in soil, that is released when the ground is torn up (e.g. when clearing an area for replanting) and then only recovers over centuries (which is essentially permanent loss, in the current context) If you cut down an entire forest to bury it (with hypothetical carbon-neutral machinery), then replant the entire forest, you can still end up emitting more carbon than you store.
