Get a product carbon footprint for everything you buy

A PCF measures the greenhouse gas emissions associated with a specific product across its lifecycle, from raw materials and manufacturing through to delivery. Unlike a corporate carbon footprint, which covers an entire organization, a PCF gives emissions data at the individual product level.

Green Project's PCF Calculator is an AI-powered tool that generates product-level carbon footprints in under 5 minutes. Enterprises use it to collect verified PCFs from their suppliers, replacing industry averages with product-specific data for more accurate Scope 3 measurement. Suppliers use it to calculate and share their product emissions with buyers, with visibility into where those emissions originate so they can take action to reduce them.

• Collecting verified product carbon footprints from suppliers at scale

• Replacing industry-average emissions factors with product-specific data for more accurate Scope 3 reporting

• Enabling suppliers at any maturity level to build PCF measurement capabilities, many for the first time

• Giving suppliers a simple, guided way to calculate and share credible PCFs with their buyers

Verified PCF data flows straight into your Scope 3 reporting, so you can see emissions by product and product line instead of relying on spend-based estimates. From there, Green Project's Decarbonization Intelligence gives suppliers tailored recommendations and access to a library of vetted reduction initiatives they can act on directly, and Renewable Energy Procurement gives them a route to cut emissions through EACs. You get visibility into hotspots and progress; your suppliers get a clear path to actually reduce them.

The PCF calculator is aligned with the GHG Protocol Product Standard, ISO 14067, the PACT (Partnership for Carbon Transparency) framework, and Together for Sustainability (TfS) guidelines. This ensures that every product carbon footprint produced is standardized, quality-checked, and recognized across industries and regulatory frameworks.

The PCF calculator includes automated quality assurance built into the calculation process. Validation checks identify data gaps, inconsistencies, and outliers in supplier submissions before results are shared with buyers.

This helps suppliers improve their data quality and gives enterprises confidence that the PCFs they receive are credible and audit-ready.

AI guides suppliers through the calculation itself. Once a supplier uploads their bill of materials, the calculator uses AI-assisted inputs to walk them through the rest of the process, matching data against emissions factors aligned with GHG Protocol, ISO 14067 and PACT. AI is also behind the automated quality checks: flagging data gaps and inconsistencies before a PCF is ever shared, so suppliers can fix issues themselves rather than having errors surface later in the process.

In short, AI removes the guesswork from calculation and catches problems early, while the methodology and standards behind the numbers stay fixed and auditable.
