This document represents a short ‘start here’ level introduction to the ‘Accounting & Reporting the Emissions of Certified Commodities’ suite of guidance documents. This document is specifically aimed at Certificate Holders and potential applicants for certification (henceforth ‘CH/A’) with ISEAL member schemes or other sustainability systems that have or are commencing on a process to align their certification of commodities and chains of custody models with emissions reporting good practices. The CH/A community for each scheme will reflect the nature of the work entailed. It is also likely that the community includes everything from very large multi-national corporation producers to smallholder and developing country cooperatives. The benefits of participating in the member’s Greenhouse Gas Reporting Systems will vary accordingly, but the broad aim for everyone is to participate in and realise the benefits of working towards mitigating the climate emergency.
