Carbon sequestration is the capture and long-term storage of atmospheric carbon dioxide, notably in agricultural soils through practices that build organic matter, and is increasingly relevant to sustainability claims in food supply chains.
In trade practice
Buyers seeking verifiable climate claims may ask suppliers to provide soil carbon measurement data or third-party assessments aligned with recognised methodologies. Organic and regenerative certification audits sometimes include soil health indicators that relate to sequestration potential. Measurement methods are still maturing, so procurement teams should distinguish between verified data and unaudited estimates when evaluating supplier sustainability reports.
In a specification
Where a buyer requires evidence of sequestration activity, the contract or sustainability annex should name the measurement methodology and the verification body responsible for confirming results.
