How Customer Carbon Footprints are Calculated

This document explains how our Product Carbon Footprint (PCF) engine calculates customer emissions, providing transparency and confidence in the results. We adhere to the Greenhouse Gas Protocol, a globally recognized standard, and undergo regular audits to ensure accuracy and compliance.

Key Principles:

• GHG Protocol Alignment: Our engine follows the ISO14067 and GHG Product Standard ensuring consistent and auditable calculations.
• Data-Driven: We use customer input data about resources (materials, energy, transport, etc.) combined with emission factors to determine carbon footprints.
• Transparency: We provide clear information about the sources of our emission factors, allowing customers to make informed choices.
• Accuracy: Our engine is designed for precision, and our processes are regularly audited.

Calculation Process (Simplified):

For more details, please view the Appendix

1. Data Input: Customers provide data about their resources, either individually or through bulk uploads using our templates. This data includes quantities, units, and other relevant information.
2. Emission Factor Retrieval: The engine retrieves the appropriate emission factors based on the resource type and customer selections. Emission factors are conversion rates that link activity data to greenhouse gas emissions (e.g., kg CO2e per kWh of electricity).
3. Unit Conversion: The engine ensures consistency by converting all quantities to the units used in the emission factor.
4. Calculation: The engine performs the calculation by multiplying the quantity of the resource by the corresponding emission factor.
5. Results: The calculated emissions are then attributed to the appropriate lifecycle stage and sector.

Resource-Specific Calculations:

• Raw Materials, Fuel, Electricity: Customers specify the material, quantity, and unit. The engine retrieves the emission factor and calculates emissions.
• Waste: The engine considers the waste treatment method (recycling, landfill, etc.) as each has a unique emission profile. Emissions are calculated for each treatment type and summed for a total waste emission.
• Transportation: Calculations consider distance, weight, and transport mode. If customers provide origin and destination, the engine can calculate the distance.
• Business Travel: Similar to transportation, calculations are based on distance, mode, and number of passengers. Air travel distances are calculated using location data.
• Hotels: Emissions are calculated based on the number of rooms booked and nights stayed.
