Standards We Follow
Green Project's PCF calculations follow internationally recognised standards: ISO 14040/14044 (Life Cycle Assessment methodology), the GHG Protocol Product Standard, and PAS 2050. These standards define which stages of the product lifecycle to include, which emission sources to account for, and how to handle data gaps and uncertainty.
What Scope of Emissions Is Covered?
A complete PCF includes upstream emissions (raw material extraction and processing, component manufacturing, and intermediate transportation), production emissions (your manufacturing processes, energy use, and waste), distribution (packaging, transportation to customer, and warehousing), the use phase where applicable, and end-of-life. Which stages are included depends on your product.
Transport Calculations
Transportation is often significant in a PCF. Green Project handles inbound transport (raw materials to your facility), transport between suppliers, outbound transport (finished products to customer), and returns where applicable.
We need the weight of materials or products, distance travelled in kilometres, transportation mode (truck, ship, air, rail), and capacity utilisation where known. We apply transport emission factors based on mode and distance, using industry-standard assumptions where you don't have exact data.
💡 Your PCF doesn't need to be perfect to be useful. It should be reasonable, clearly documented, and consistently calculated year-over-year so you can track improvements.
