GHG CleanStart Registry: A registry to publicly report your carbon footprints, and showcase carbon reduction commitments and actions.

CSA's GHG CleanStartTM Registry is a credible and transparent service for reporting carbon footprints/inventories and/or carbon reduction commitments and actions. It can also be the first rung on the ladder to recognition through CSA's Registered Carbon NeutralTM Program. To be eligible to post on the registry, companies follow the internationally recognized ISO 14064 series of standards for greenhouse gas inventories and reporting.
