First Movers Coalition Cement And Concrete Commitment

Scenario FMC guidance Recommended actions can be counted against the FMC commitment 4. Product carbon footprint states net emissions10 for non-biogenic waste fuels Gross emission figures should be used when analysing if a product meets the FMC threshold to include the emissions impact from non-biogenic waste fuels Engage supplier for data on gross emissions; these are typically used by suppliers internally to be able to calculate the net emissions 5. A concrete producer claims that injecting CO2 into its concrete reduces the product carbon footprint In the concrete's product carbon footprint, a producer may claim emissions reductions from reducing their concrete's cement content, but may not claim the additional emissions benefit from the capture and injection of CO2 to avoid double counting of avoided emissions. However, carbon dioxide removal credits for this capture process may separately count towards the member's FMC CDR sector commitment Work with suppliers to ensure guidance is followed. If members are interested in removals, they should consider joining FMC's Carbon Dioxide Removals (CDR) sector 6. Concrete does not meet concrete-specific FMC standard but constituent cement meets cement-specific FMC standard Signatories are allowed to choose between a cement-specific and concrete-specific commitment for a given purchase Have internal conversations about whether a cement-specific or concrete-specific standard makes more sense for ease of measurement and communication 7. Reported emissions include recarbonation impact during concrete use FMC emissions calculations cannot include recarbonation impact in concrete use (e.g., absorption of CO2 by concrete sidewalk over time) Engage supplier for data on the recarbonation impact and remove it from the product carbon footprint 1 Includes emissions from modules A1, A2, A3 in lifecycle analysis (cradle-to-gate) as per EPD standards for Portland Cement and/or ready-mix concrete. 2 Water to cementitious materials ratio varies across strength classes but is generally lower for higher strength concrete mixtures (NRMCA). 3 Identity preserved: “the materials or products originate from a single source and their specified characteristics are maintained throughout the supply chain” ISO 22095:2020 4 Segregated: “specified characteristics of a material or product are maintained from the initial input to the final output” ISO 22095:2020 5 Controlled blending: “materials or products with a set of specified characteristics are mixed according to certain criteria with materials or products without that set of characteristics resulting in a known proportion of the specified characteristics in the final output” ISO 22095:2020 6 Mass balance: “materials or products with a set of specified characteristics are mixed according to defined criteria with materials or products without that set of characteristics” ISO 22095:2020 7 Book & claim: “The administrative record flow is not necessarily connected to the physical flow of material or product throughout the supply chain” ISO 22095:2020 8 Emissions from all fuels burned (e.g., non-biogenic waste fuels) are included in the product carbon footprint; Note: biogenic waste fuels are considered emissions-free for purposes of the FMC commitment, in alignment with typical cement/concrete EPDs. 9 All carbon removal processes must account for and quantify their net CO₂ emissions removals from the atmosphere (e.g., complete a lifecycle assessment which considers the greenhouse gas (GHG) emissions incurred during transportation, sequestration (including energy use), and utilization). 10 i.e., excludes emissions impact from non-biogenic waste fuels.
