IMHO, the only activity that should have ever been considered as carbon-negative is actually taking carbon out of the air, and storing it in the ground somehow.

IMHO, the only activity that should have ever been considered as carbon-negative is actually taking carbon out of the air, and storing it in the ground somehow. IT is extremely expensive, which highlights why it is so important to prevent carbon emissions in the first place.
All of these suggestions which seek to reduce someone else's carbon output somehow, seem fraught with moral hazard or other significant problems.

While the reality is that pumping co2 into oil wells helps get more oil out, and then eventually the co2, at high pressure, converts to carbonic acid in the water, and flows out. And since carbonic acid is acidic, whatever tiny crack it finds to get out of will rapidly get larger as fast moving acidic fluid erodes it bigger and you have a sudden release of massive quantities of 'stored' CO2.
