I feel like there's a lot of these carbon-sequestration companies that are selling absolute poppycock and getting billions in funding, and very little actual oversight. They're doing this song and dance with "carbon credits", and eventually someone's going to peek behind the curtain and blow their cover.
I haven't seen one carbon-sequestration entity yet, besides those that are focused around planting trees, that have actually shown any real results other than vague handwavey bullshit. Like the ones saying they're capturing it out of the air and pumping it underground -- awfully convenient that nobody can fucking verify that it's actually happening eh?
70,000 tons "to date" is a heck of a lot less than 37 billion tons annually. It would take over 500,000 identical facilities with no environmental impact to reach net zero.
Most locations aren't like that; they're injecting into oil and gas deposits with the risk of subsequent leakage
Enhanced rock weathering is very cool if it can be made to work at scale. Most examples have issues with needing a lot of energy to mine and pulverize rocks
