Construction Project Embodied Carbon Assessment Checklist [FREE PDF]

Embodied carbon in construction materials accounts for up to 11% of global greenhouse gas emissions and is increasingly regulated under frameworks like ISO 14064-1 and the GHG Protocol Scope 3 Standard. This checklist guides project teams through a systematic assessment of cradle-to-gate and cradle-to-grave carbon emissions embedded in construction materials, processes, and logistics. Completing this assessment supports compliance with Science Based Targets (SBTi) value chain requirements and en

Project Scope & System Boundary Definition

Establish the assessment boundary, lifecycle stages, and reporting period for embodied carbon quantification.

Has a defined system boundary been established for the embodied carbon assessment (cradle-to-gate, cradle-to-site, or cradle-to-grave)?
Are all lifecycle stages (A1–A5, B1–B7, C1–C4, D) documented and accounted for in the assessment scope?
Has a baseline reference building or benchmark been identified for comparison?
Is the gross floor area (GFA) of the project recorded in the assessment documentation?
Have all significant emission sources been identified and listed in the project carbon register?

Material Carbon Data Collection & Verification

Verify that carbon factor data for key construction materials is sourced from credible, up-to-date Environmental Product Declarations (EPDs).

Are Environmental Product Declarations (EPDs) collected for all major structural and finishing materials?
Are EPDs used in this assessment verified by an accredited third-party program (e.g., EPD International, UL, IBU)?
Have secondary (industry average) carbon factors been used where EPDs are unavailable, and has this been documented?
Is the Global Warming Potential (GWP) unit (kgCO2e/unit) correctly applied for all materials using AR5 or AR6 characterization factors?
Is total embodied carbon per material category recorded in kgCO2e?
Has a material quantity take-off (QTO) been completed and cross-referenced against design drawings?

Construction Process & On-Site Emissions

Assess direct emissions from construction machinery, temporary works, site energy use, and waste generation during the construction phase (stages A4–A5).

Are fuel consumption records for all diesel and petrol construction equipment tracked and documented on-site?
Is site electricity consumption metered separately and reported in kWh for the assessment period?
Are construction waste volumes recorded by waste stream (e.g., concrete, timber, steel, mixed waste) in tonnes?
Are refrigerant fugitive emissions from site welfare units and temporary HVAC systems tracked?
Is a carbon reduction plan in place for construction-phase activities targeting measurable emission reductions?

Transport & Logistics Emission Assessment

Quantify upstream transport emissions for material delivery and downstream waste transport (stages A2, A4, C2).

Are material transport distances (from manufacturer/supplier to site) documented for all primary materials?
Are transport emission factors applied based on vehicle type (HGV, rail, ship) and fuel type?
Is the proportion of materials sourced locally (within 50 km) calculated and documented to support carbon reduction claims?
Are waste transport emissions to landfill, recycling, or incineration facilities calculated separately?
Total calculated transport emissions for the project (kgCO2e)?

Carbon Calculation Methodology & Tools

Verify the calculation tool, methodology version, and data quality applied in the embodied carbon quantification process.

Is an industry-recognized embodied carbon calculation tool used (e.g., One Click LCA, Tally, EC3, CarboniCa)?
Has the calculation methodology been documented, including all assumptions and data sources?
Has uncertainty analysis been performed to estimate the range of potential error in the carbon calculation?
Is the total whole life carbon intensity of the project expressed in kgCO2e/m² (GFA)?
Have carbon calculation results been reviewed and approved by a qualified carbon professional or third party?

Carbon Reduction Design Strategies

Document and evaluate design decisions and material substitutions implemented to reduce embodied carbon below baseline.

Have low-carbon material substitutions (e.g., low-carbon concrete, recycled steel, mass timber) been evaluated and documented?
Has structural optimization been performed to minimize material volumes while meeting structural performance requirements?
Are reclaimed or recycled content materials included in the design to reduce upstream extraction emissions?
Has a Design for Disassembly (DfD) or Design for Reuse strategy been incorporated to reduce end-of-life emissions (lifecycle stage C)?
Is the estimated carbon reduction achieved versus baseline documented as a percentage?

Reporting, Disclosure & Verification

Confirm that embodied carbon results are reported in compliance with applicable disclosure frameworks and submitted for third-party verification.

Has an embodied carbon assessment report been prepared in accordance with ISO 14064-1:2018 reporting requirements?
Are embodied carbon results disclosed in the organization's annual CDP Climate Change questionnaire under C6.5 (Scope 3)?
Has the embodied carbon assessment been submitted for third-party verification in line with ISO 14064-3:2019?
Are embodied carbon results uploaded to a publicly accessible database or registry (e.g., EC3, Carbon Smart, LETI)?
Is a corrective action plan documented for findings identified during the embodied carbon assessment?
Additional notes on embodied carbon assessment findings, limitations, or recommended next steps?
