Scope 3: Primary data for your Coporate Carbon Footprint
Get in touchVia Network by ClimatePartner, buying companies connect with their suppliers: the Product Carbon Footprints from the supply chain become their primary data for Scope 3. Every PCF replaces an estimate and makes the carbon footprint more accurate.
Scope 3.1 without primary data: The weak spot in your carbon footprint
Up to 90% of a company's emissions originate in the upstream value chain. The majority falls under scope 3.1: Purchased Goods & Services. This category is difficult to measure and is often calculated using estimates or secondary data that lack accuracy or are subject to fluctuation. The result: a decarbonisation strategy built on assumptions and reduction measures that miss the mark.
Supplier-specific Product Carbon Footprints (PCFs) in four steps
Via Network, customers connect with their suppliers for structured PCF data exchange. Verified primary data flows directly into the carbon footprint, replacing scope 3.1 estimates.
1. Inviting suppliers | Use the mass upload to onboard suppliers to the platform in a single step. Customers can prioritise suppliers based on their impact on scope 3.1 emissions. |
2. Collecting data | Your suppliers calculate or upload their PCF independently or with support from ClimatePartner experts. Step-by-step guidance simplifies the first steps and helps with data collection and submission. |
3. Validating calculations | ClimatePartner validates PCFs. Customers are notified if the data does not meet their requirements. Suppliers then receive feedback and support to close any gaps. The result: PACT-compliant PCFs with transparent data quality scoring. |
4. Integrating primary data | Suppliers share their PCFs via Network. The data flows directly into your scope 3 calculations, replacing estimates with primary data. This lays the foundation for fact-based decisions on decarbonisation and procurement. |
Better supplier support. Better scope 3 data.
Many suppliers don’t know how to calculate their PCF. Without active support, data requests go unanswered and gaps remain. ClimatePartner experts support your suppliers from carbon accounting to the implementation of concrete reduction measures. You benefit from reliable scope 3 upstream data and suppliers who are reducing their carbon footprint.

Frequently asked questions about scope 3.1 and Network by ClimatePartner
Scope 3.1—Purchased Goods & Services—is the largest emissions category for most companies. The emissions occur at your suppliers, not within your own operations. Without supplier-specific PCFs, the only option is to calculate using generic averages, which lack accuracy, are subject to fluctuation, and provide an unreliable basis for reduction decisions that need to hold up to scrutiny.
Via Network, customers connect with their suppliers on one platform. Suppliers calculate their PCF in Network and share the data with their customers. The results flow directly into the customer's scope 3 calculations, replacing estimates with primary data.
The platform allows you to import suppliers via mass upload, either in stages or all at once with a single click. This allows customers to start with the suppliers that have the greatest impact on their scope 3.1 footprint.
Yes. You can calculate your PCF independently or with support from ClimatePartner experts, from data collection through to a finished, PACT-aligned result. You decide how much support you need.
No. You calculate your PCF once and share it with multiple customers via the platform. This saves time and significantly reduces the effort involved in responding to recurring customer requests.
