Unclear: Sandy is still used in 2026 (e.g. Woldmarsh members), but the company page is dated 2021 and we could not confirm that credits are currently being bought through Trinity NCM. Soil carbon credits can be reversed if practices stop or soils lose carbon, so schemes keep a buffer and may claw back. Prices are not fixed and depend on buyers. Measurements are disputed (much soil carbon sits below the 30 cm usually sampled). There is still no published UK Farm Soil Carbon Code. Check data ownership, exit rules and what happens to SFI stacking.
