It costs money to capture carbon — whether it’s reforestation, or switching pasture to organic farming, scaling up an aquatic carbon sink of some kind, etc. So it’s definitely beneficial. And with properly audited trade markets, it should be reliable for “cancelling” emissions. At the moment it’s cheap. But as the market becomes saturated it’ll naturally get more expensive to offset; ideally that leads to innovations in other ways of reducing emissions. And, of course, we need to eventually get to negative emissions to reverse the warming we’ve already locked in.
