A new module for book and claim

Isometric has released a draft Book and Claim Module for public consultation, open through July 1, 2026. The module establishes guidelines for issuing, monitoring, and retiring certificates when environmental attributes are separated from physical goods, spanning low-carbon materials, sustainable fuels, energy, and other sectors. It supports Isometric’s expansion into Environmental Attribute Certificates announced in April, to be followed by sector-specific protocols beginning with low-carbon materials.
