Sweep, the AI-powered sustainability platform, and Climatiq, the product carbon intelligence company, have announced a partnership that brings Climatiq’s ISO 14067-certified calculation engine into Sweep’s supply chain offering. Together, they power a new conversational AI experience that makes supplier product carbon footprints (PCFs) easier to request, easier to produce, and easier to trust.
Most companies now know that spend-based estimates of their purchased goods (Scope 3 Category 1) won’t hold up for much longer. But most suppliers have never calculated a PCF, and the data they do send is often incomplete, inconsistent, or impossible to check. This partnership helps global buyers fill the data gap for Scope 3.1 emissions reporting by supporting suppliers with little or no carbon expertise to produce audit-ready product carbon footprints (PCFs) inside Sweep. PCF Campaigns let buyers ask each supplier, in a single request, for the footprints of everything they supply. Suppliers that already have PCFs simply upload them.
Under the agreement, Climatiq’s ISO-verified calculation engine, covering market-leading emission factors across 60+ providers and 300+ regions, will power a guided PCF flow inside Sweep’s supply chain offering. A supplier uploads a bill of materials, and Sweep’s AI combined with Climatiq’s emission factor matching, fills the gaps in the supplier’s data and produces a usable, auditable PCF that’s aligned with the PACT methodology. And because every Guided PCF uses the same method, buyers can compare footprints across their supplier base and see which purchased products to focus on for sourcing and reduction.
The announcement comes as buyers face growing pressure to move Scope 3 reporting beyond generic, spend-based industry averages. California’s SB253 requires large companies operating in the state to report Scope 1, 2 and 3 emissions, and CSRD obligations are extending to the US subsidiaries of European multinationals. For most buyers, a large share of their suppliers have never calculated a product carbon footprint, and starting from a blank page slows every Scope 3.1 program down.
Guided PCF builds on Sweep’s layered approach to supplier engagement: buyers start with an industry-level hotspot estimate to identify which suppliers matter most, move to supplier-specific enrichment when they need a sharper Scope 3.1 picture, and can now fund certified PCF calculation, powered by Climatiq, for the suppliers where precision matters most. The new conversational AI flow makes that step faster, more intuitive, and easier to scale across complex supply chains.
Climatiq’s Mapping Agent for emission factors supports 47 languages and they count companies such as Celonis and IntegrityNext among its customers. Sweep serves enterprise customers including L’Oréal, Thales and Crocs. The partnership brings both networks together around a single, compliant path from supplier data to Scope 3 reporting.
Rachel Delacour, CEO and co-founder of Sweep, said:
“Heads of sustainability all tell us the same thing: they’d rather have estimated supplier emissions data than supplier-provided data they can’t defend. With Climatiq, we’re giving every supplier, including those starting from scratch, a simple way to produce a credible product footprint, and giving buyers numbers they can actually stand behind in their Scope 3 reporting. This partnership turns a complex, expert-heavy process into a guided AI-driven conversational experience inside Sweep.”
Hessam Lavi, co-founder and CEO of Climatiq, said:
“Climatiq’s mission has always been to put carbon intelligence at the heart of business decision-making. Partnering with Sweep helps us deliver that by making reliable product-level carbon insights accessible across enterprise supply chains at a whole new scale, so that emissions more visible than ever.”
