Time scale is also something I want to know about. "Can I remove CO2 from the air and turn it into something valuable in a way that is cost effective?" is one question. Another question is, "Can I remove CO2 from the air and turn it into something valuable faster than a tree?"

In some climate zones, grasslands do it better than forests.

A tree gives you wood. What are the valuable outputs of grasslands?

You can make it into a carbon-neutral heating fuel.

You can make paper products including things like cardboard and packaging.

You can put livestock on it and produce meat.

Or if you just want to sequester carbon, you can harvest it and bury it deep in the ground.
