Sample specification language for incorporating low carbon concrete requirements into construction projects. Includes a nonresidential specification with detailed clauses covering cement limits, GWP path compliance, CO2 mineralization technology, submittal requirements, and alternate mixture provisions; and a residential specification with simplified language suitable for single-family and small multifamily projects, including compliance forms and guidance on letting the ready-mix supplier design optimal mixes. Both specifications provide two compliance paths: a cement limit method and an embodied carbon (GWP) method.
