Product Carbon Footprint Assessment

Service summary

An independent review of an existing product carbon footprint study. The assessment examines the study boundary, data sources and methodological choices supporting the reported product-related greenhouse gas result.

Findings help the study owner understand reliability and comparability limitations. The service does not calculate a new footprint, declare carbon neutrality or establish environmental superiority over competing products.

Key objectives

• Assess study boundary consistency
• Examine lifecycle data evidence
• Evaluate allocation and calculation assumptions
• Identify limitations affecting footprint interpretation

Methodology

The existing study is compared with agreed methodological criteria, using selected data tracing and checks of influential assumptions.

• Agree the product, study purpose, methodology and review boundary.
• Review the functional or declared unit and lifecycle coverage.
• Select significant contributors and uncertain inputs for examination.
• Trace source data, factors and allocation choices.
• Check selected calculations and treatment of exclusions or assumptions.
• Evaluate interpretation, comparability and reporting limitations.
• Issue a qualified study review without formal verification claims.
