Supplier Data Quality & Proxy Validation Review

Supplier Data Reliability and Proxy Assessment Delivered Within 48–72 Hours

Many organizations depend on supplier-provided data to support Scope 3 inventories, Product Carbon Footprints, LCA studies, and EPD development, yet the underlying inputs are often incomplete, inconsistent, or unsupported by sufficient documentation.

When proxy data is used without clear validation, reporting confidence declines, comparability is weakened, and decision-making becomes exposed to technical risk. A structured review is essential to understand what can be trusted, what requires improvement, and where assumptions may undermine results.

What We Review

• Supplier data completeness and internal consistency
• Reliability of supplier-provided inputs and documentation
• Use of proxy data, substitutions, and assumptions
• Representativeness of data across suppliers, regions, and processes
• Data quality risks affecting carbon, LCA, PCF, or EPD results
• Overall suitability of supplier data for reporting and decision-making use

What You Receive

• Clear identification of weak, incomplete, or unreliable supplier data
• Assessment of proxy use and validation risks
• Highlighted inconsistencies affecting data credibility and comparability
• Structured summary of findings and major risk areas
