Are there any product carbon footprint software platforms that focus on product-level customer requests and disclosures?

Yes. A few product carbon footprint (PCF) platforms are specifically built around product-level customer requests, supplier data collection, and disclosure/response workflows rather than just internal emissions accounting.

Examples include:

• CarbonChain – focuses on product and supply-chain emissions data, often used for customer reporting and product-level traceability.
• Tanso – offers product carbon footprinting with workflows for collecting supplier-specific data and responding to customer requests.
• Normative – broader carbon accounting platform, but includes product-level emissions and customer disclosure use cases.
• Sourcemap – strong on supply-chain mapping and product traceability, useful when customers ask for product-specific footprint disclosures.
• Emitwise – has product carbon footprinting and supplier engagement features aimed at customer and procurement requests.
• Ecotrace / Trace-based PCF tools (various vendors) – these are often designed for automated product-level disclosures and buyer questionnaires.

If your main need is “a platform that helps answer many customer PCF requests for specific products, with auditability and supplier evidence”, the key features to look for are:

1. Product-level PCF calculation
2. Supplier data collection and collaboration
3. Customer request management / disclosure workflows
4. Audit trail and evidence attachment
5. Export formats such as PCF sheets, ESG questionnaires, or digital product passports
6. Support for standards like ISO 14067, GHG Protocol Product Standard, PACT Pathfinder, or Catena-X

If you want, I can also give you:

• a shortlist by industry (manufacturing, chemicals, food, electronics), or
• a comparison table of these platforms by customer-request/disclosure capabilities.
