Cement & Concrete
Cement and concrete constitute approximately 8% of all global emissions, and demand is expected to grow significantly for this crucial construction material by 2050. Low-emissions solutions for cement and concrete exist, however the supply is limited and carries a price premium compared to conventional products. Cement and concrete producers need clear signals that there is sizable demand for low-emissions products to justify the high capital costs required to finance low-carbon cement production.
GMA and RMI are partnering on an initiative to address these challenges by facilitating capital deployment towards low-carbon cement and concrete, enabling dramatic reductions to embodied emissions in the built environment. This initiative will operate in two phases: first leading a diverse working group to design a credible measurement and book and claim system, and, subsequently, establishing a collective procurement process for both physical and attribute offtake similar to other programs such as the Sustainable Aviation Buyers Alliance (SABA), GMA Trucking, and Sustainable Steel Buyers Platform.
Book and claim system design to spur cement and concrete innovation
In August 2025, GMA and RMI published a draft book and claim framework for low-carbon cement and concrete products. The framework reflects months of collaboration and iteration with a Working Group of more than 30 experts from across the cement and concrete value chain, a process that began in December 2024.
This draft framework aims to generate a representative, sector-specific perspective on how book and claim should be applied in the cement and concrete industry. The proposal is an effort to create a widely applicable opportunity for market actors to engage in book and claim, creating greater confidence and bankability of environmental attribute certificate (EAC) mechanisms and ultimately contributing to industry decarbonization goals.

A public comment period is open from August 27 – September 19, 2025. A link to the feedback form is contained within the draft framework document.
Cement and concrete make up 8% of global emissions
Demand for concrete and cement is expected to grow 40% by 2050
Lack of clarity for end users to reach ambitious climate targets
GMA is engaging with stakeholders to:
Review and align on measurement methodologies for attributes or certificates
Build the book and claim structure for concrete attributes
Identify additional key stakeholders to engage
Provide market intelligence to ensure GMA designs the system in a way that addresses real business and sustainability needs
