Sylvera explains book-and-claim mechanism for decarbonising heavy industry supply chains

Sylvera has published an explanation of the 'book-and-claim' mechanism, detailing its application for decarbonising heavy industrial supply chains. This system allows producers to sell physical low-carbon products locally while selling the associated environmental attribute to a different entity, tracked by a registry to prevent double-claiming. The mechanism is particularly relevant for heavy industries like cement, steel, and aviation fuel, where physical transport of low-carbon alternatives is often impractical or emissions-intensive. Sylvera distinguishes between mature energy attribute certificates (EACs) for Scope 2 emissions and nascent environmental attribute certificates for Scope 3, noting differences in market maturity and pricing transparency.
