Google just did its first megaton rock-weathering deal. What stuck with me isnt the headline volume. Its that the tonne and the temperature window are not the same product. Most claim decks still treat them like they are. Dan Harburg and I sat with Connor Sendel (CCO / founding team, Terradot) on Carbon Weekly News (CWN) at Climate Week NYC. ↓ 4 things that matter if you actually buy this stuff: 1. How one land book can run two ledgers without collapsing the claim Same southern Brazil rice fields: AWD cuts methane near-term; ERW delivers permanent removal later. >200k hectares under that model. If your claim language flattens both into “2 Mt permanent,” you’re already wrong on product, window, and what you can say in public. 2. Why “net-zero warming from the first credit” is the diligence line, not the 2040 slide Methane buys a ~12-year climate-impact window (half-life / GWP-20). That covers the weathering lag so durable tonnes can land inside the window. First deliveries ~2028; permanent CDR targeted by 2040. Ask for the matching math on GWP-20 vs permanence timing - not the press line. 3. How soft costs can double ���/t without buying you more climate Rock-on-field is the hard cost. Project finance plus frequent MRV to service debt is the soft cost that can double delivered €/t with zero extra impact. This stack tries to pay for climate-impact coverage instead of paying to carry the lag. 4. Why this is not a permanence trust dressed up as an offtake Connor’s cut: both interventions are already complete when you claim. You’re not parking cash hoping future DAC gets cheap enough. Closed system vs an option on someone else’s future factory. (links in comments)
