Takeaways
- Product Carbon Footprint data is often incomplete because companies rely on supplier estimates, inconsistent activity data and legacy spreadsheets.
- The most common gaps include missing supplier data, weak activity data, inconsistent emission factors, unclear system boundaries and poor documentation.
- Better data governance improves ISO 14067 reporting quality and makes EU Digital Product Passport preparation more manageable.
- Reliable emissions data can also support CBAM-related customer requests, especially for exporters supplying EU-facing value chains.
- Malaysian exporters should strengthen Product Carbon Footprint data early if they supply products to EU buyers or operate in sectors exposed to EU sustainability and carbon requirements.
What is Product Carbon Footprint Data?
Product Carbon Footprint data is the information used to calculate greenhouse gas emissions linked to a product across its life cycle. This may include raw materials, supplier processes, energy use, transport, manufacturing, packaging, use phase and end-of-life treatment, depending on the chosen system boundary.
For companies preparing product-level emissions reporting, the official ISO 14067 standard provides principles, requirements and guidelines for quantifying and reporting the carbon footprint of products. The GHG Protocol Product Standard is also useful for understanding product life-cycle emissions.
This article builds on our first article, EU Digital Product Passport Under ESPR: What Malaysian Exporters Need to Know, which explains how the EU Digital Product Passport under ESPR will require more structured product information. Product Carbon Footprint data is one of the key areas companies should strengthen for future DPP readiness.
For Malaysian exporters, this also connects with the Carbon Border Adjustment Mechanism, or CBAM. While CBAM and Product Carbon Footprint reporting are not the same, both depend on reliable emissions data, supplier information and auditable records.

Why Product Carbon Footprint Data is Often Incomplete
Product Carbon Footprint data is rarely complete on the first attempt. Many companies start with information that is easiest to access, such as utility bills, supplier declarations, procurement records or existing sustainability reports.
That may be enough for an internal estimate, but it is usually not strong enough for ISO 14067-aligned reporting, customer due diligence, CBAM-related requests or EU Digital Product Passport readiness.
The challenge is that product carbon footprinting depends on data from multiple functions and supply-chain tiers. Procurement, production, logistics, finance, sustainability, quality and suppliers may all hold different parts of the calculation. If these data sources are not aligned, the final footprint may look precise while still being methodologically weak.
This is similar to the wider GHG reporting challenge discussed in our article on GHG Scope 1 and Scope 2 Verification in Malaysia, where emissions data must be complete, traceable and supported by reliable evidence.
Common Gap 1: Supplier Data is Missing or Inconsistent
Supplier data is one of the most frequent weak points. A company may know the weight of a component but not the material origin, energy used during processing or emissions from outsourced operations.
Common issues include missing material composition, incomplete country-of-origin information, inconsistent supplier templates, no record of upstream process changes and limited visibility into subcontracted processes.
The fix is to standardise supplier requests early. Ask relevant suppliers for the same core data fields and build these requirements into contracts, purchase terms or supplier onboarding documents. A simple supplier data template is often more effective than a general request because it tells suppliers exactly what information is needed.
Common Gap 2: Activity Data is Too Weak
Activity data refers to operational information used in the footprint calculation, such as electricity use, fuel consumption, transport distance, production volume, yield losses and process throughput.
Many companies have activity data, but not in a product-specific form. Factory data may be recorded at site level rather than by product line. Transport data may be estimated instead of measured. Production losses may not be allocated clearly to specific products.
To fix this, companies should identify the activity data needed for each product family, separate site-level data from product-specific data, use metering or process logs where possible, and track transport by route, mode and frequency. Businesses building GHG data capability can also refer to our article on GHG Scope 1, 2 and 3 emissions in Malaysia to understand how activity data, emission factors and documentation work in practice.
Common Gap 3: Emission Factors are Inconsistent
Emission factors are often taken from different databases, years or geographic contexts. This can lead to results that are difficult to compare or defend. For example, one product may use a Malaysia grid electricity factor, another may use a regional average, and another may use a supplier-provided factor with no visible source.
The practical fix is to create a hierarchy for emission factor selection. Use supplier-specific or primary data where appropriate, then use clearly defined secondary sources where primary data is unavailable. Record the source, year, geography and rationale for every factor used.
Common Gap 4: System Boundaries are Unclear
A Product Carbon Footprint can change significantly depending on whether the boundary is cradle-to-gate, cradle-to-grave or another defined scope. Problems arise when boundaries are unclear or when different product lines are calculated using different scopes without explanation.
To fix this, companies should define the functional unit, specify the system boundary, apply consistent logic across comparable products, document exclusions and ensure customer-facing summaries do not overstate what the study covers. Clear boundaries are essential for ISO 14067 reporting and for carbon-related disclosure that may support CBAM or DPP readiness.
Common Gap 5: Documentation is Too Thin
Even when calculations are technically sound, poor documentation can undermine the whole exercise. A Product Carbon Footprint without supporting notes is difficult to review, repeat or verify.
Companies should treat every PCF project as an auditable record. Keep version-controlled calculation files, supplier evidence, assumptions, exclusions, factor sources, update dates, approval logs and review comments. For organisations preparing for verified emissions reporting, our article on How to Implement ISO 14064 for Verification in Malaysia explains why reliable data and documented methodologies are essential for credible GHG claims.
How to Improve Product Carbon Footprint Data Collection
The best way to improve Product Carbon Footprint data is to make collection repeatable. One-off projects often produce uneven results because each team uses different assumptions, formats and evidence.
A better process should include a data owner for each input category, a standard supplier request template, a review cycle for assumptions and emission factors, a controlled calculation workbook or digital platform, and a sign-off step before data is shared externally.
Companies should also prioritise. Start with products that are high volume, high emission, strategically important or most likely to face EU customer scrutiny. This helps reveal the data issues most likely to affect wider implementation.
Digital Tools that Support ISO 14067, CBAM and DPP Readiness
Manual spreadsheets may work for early pilots, but they become harder to manage as data volume increases. A digital Product Carbon Footprint platform can help centralise inputs, standardise supplier submissions, reduce manual errors and maintain an audit trail across product lines.
Digital tools support ISO 14067 by improving traceability, comparability and repeatability. They support CBAM by organising emissions evidence for EU-facing trade. They also support DPP readiness because the Digital Product Passport is expected to rely on structured, machine-readable product data rather than unstructured documents.
When the same workflow is used repeatedly, companies can compare product footprints more reliably and respond faster to customer, auditor or regulator requests.
Practical Checklist to Fix PCF Data Gaps
Companies can use this checklist as a starting point:
- Identify the product families most likely to need a footprint first.
- Map every data source used in the calculation.
- Replace informal supplier estimates with standard templates.
- Define system boundaries before refining the numbers.
- Use consistent emission factor sources.
- Keep full documentation for every assumption.
- Review the output with technical and commercial stakeholders.
- Plan for verification if the data will be shared externally.
- Move from scattered spreadsheets to a repeatable digital workflow.
- Connect PCF data improvements with ISO 14067, CBAM and DPP readiness planning.
Conclusion
Product Carbon Footprint data gaps are common, but they are fixable. The most important improvements come from better supplier engagement, clearer boundaries, consistent emission factors, stronger documentation and repeatable data collection.
For Malaysian exporters, improving Product Carbon Footprint data is a practical step towards ISO 14067 reporting, CBAM readiness and EU Digital Product Passport preparation.
