B2 Carbon

Construction Embodied Carbon and Scope 3 Tracking

Bricks & Brains connects BOQs, supplier quotations, purchase orders, EPDs and delivery records to build a living embodied-carbon ledger for construction projects.

How it works

From material data to a living carbon ledger

Carbon is calculated from quantities and emissions data, then updated as the project moves from design assumptions to real procurement and delivery records.

The live supply-chain twin connects quantities, supplier/product factors and procurement actuals so the carbon ledger stays traceable as the project evolves.
Carbon states

Track carbon from design to as-built

The key is not pretending early estimates are final. Bricks & Brains keeps the carbon view tied to the maturity of the supply-chain data.

01 · Baseline

BOQ or design quantity × available EPD or approved generic factor.

02 · Procured

Awarded supplier + product-specific factor + committed order quantity.

03 · Delivered / As-built

Actual delivered quantities, substitutions and relevant logistics information.

Procurement decision support

Put carbon beside cost and lead time

Where comparable data exists, Bricks & Brains can help procurement teams understand the trade-offs between commercial price, delivery performance and embodied carbon before an award is approved.

  • Price. Commercial comparison from supplier bids.
  • Lead time. Delivery commitment and schedule exposure.
  • Risk. Supplier and logistics signals.
  • Carbon. Product EPD or approved factor × relevant quantity.

From assumptions to actuals

Start with design quantities, then progressively replace assumptions with awarded suppliers, product EPDs, committed quantities and delivery records.

Material-level traceability

Keep quantity, supplier, factor source and carbon result connected so each calculation has a clear data trail.

Carbon inside procurement

Bring embodied carbon into supplier evaluation rather than calculating it only after commercial decisions are complete.

FAQs

Embodied carbon, answered

How does Bricks & Brains calculate embodied carbon?

Bricks & Brains links material quantities to product-specific EPDs or approved emission factors. The calculation can evolve from design or BOQ quantities to awarded, procured and delivered quantities as better project data becomes available.

Is this direct measurement of CO₂ emissions?

B₂ Carbon calculates embodied carbon from material quantities and appropriate emissions data such as EPDs or approved factors. Bricks & Brains keeps those calculations connected to procurement and delivery records that represent what the project is actually buying and building.

Can it compare suppliers on carbon before award?

B₂ Carbon can surface carbon alongside price, lead time and supplier risk when comparable EPD or emissions data is available, supporting procurement decisions before award.

Is this intended to replace an LCA tool?

B₂ Carbon focuses on construction materials and on making procurement and delivery data usable for embodied-carbon intelligence. The product can complement broader LCA, certification and reporting workflows.

Connect carbon to the materials you actually buy

Start with one project or material package and build the carbon ledger from your existing procurement data.
