I couldn't tell from the site, is this "offsets" or actual carbon sequestration? And because sometimes the difference is fuzzy, is it paying for stuff that would have happened anyway, or is it somehow net removal? I saw a "method" chart but it had no labels on my phone so maybe it's addressed there.

I had the same question. There’s an explicit breakdown in one of the graphs, Suppliers and a graph on Price Per Method. They cover both obvious approaches to Direct air capture (DAC, Electrochemical Ocean Capture) and less obvious ones (BioChar, Biooil, Mineralization, Enhanced weathering, Biomass removal, Macroalgae). I suspect that the inclusion of some on a reference dashboard will increase their legitimacy, and lower the case for approaches not included here. I also expect that companies will start favoring the cheapest approach.

Voluntary carbon markets typically trade in both avoidance and removal (i.e. sequestration) credits. Since this site is called Carbon Dioxide Removal I would assume listed trades only cover sequestration, and my cursory review of the listed removal methods appears to confirm that only sequestered carbon trading is listed (but the methods section does not state this explicitly). Regarding "is it paying for stuff that would have happened anyway, or is it somehow net removal?": One of the requirements for generating carbon credits is additionality, i.e. a project should only receive carbon credits if it were not viable without the revenue from those credits. But as you point out, determining additionality is rather difficult and often fuzzy.

Good question! CDR.fyi aggregates purchases, deliveries, and verifications of carbon removed and stored for more than 100 years CDR.fyi does not track things like "avoided emissions" (like switching your fleet from gas to EV) or lower-permanence solutions (like planting trees) (Methods show up on that chart when you hover, but good UX feedback there :)
