Sweep and Climatiq Link Engines to Deliver Supplier Product Carbon Footprints

Sweep and Climatiq have launched a joint offering that lets companies request and receive product carbon footprints (PCFs) directly from their suppliers, a move aimed squarely at the Scope 3 data gap now sitting under the EU's CSRD and California's SB253.

The partnership, announced by the two companies, pairs Sweep's enterprise sustainability data management platform with Climatiq's carbon calculation engine. The target audience is explicit: buyers under pressure to move Scope 3 reporting beyond generic, spend-based industry averages — and suppliers who have never calculated a product carbon footprint at all.

What does the deal actually build?

Technically, the integration works as a guided flow inside Sweep's supply chain offering. A supplier uploads a bill of materials. Sweep's AI and Climatiq's emission factor matching then produce an auditable, PACT-aligned product carbon footprint.

That last detail matters. PACT — the Partnership for Carbon Transparency — sets the methodological standard for comparable product-level footprints, and alignment with it is what turns a supplier's estimate into a number a buyer can use in reporting.

Because every supplier works through the same methodology, the companies say buyers can compare footprints across their supplier base and identify which purchased products to prioritise for sourcing changes and emissions reduction.

Why now?

The regulatory driver is the whole story. Both the Corporate Sustainability Reporting Directive in the EU and California's SB253 climate disclosure law push large companies to report Scope 3 emissions with more rigor than industry-average, spend-based estimates allow.

The problem, as Sweep and Climatiq frame it, is that much of the supplier base has no capacity to produce product-level data. Reporting obligations sit with the buyers; the calculation capability does not.

Rachel Delacour, CEO and co-founder of Sweep, put the buyer's dilemma bluntly:

"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."

Hessam Lavi, co-founder and CEO of Climatiq, framed the partnership as a scaling play for product-level carbon intelligence:

"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."

Estimated data versus defensible data

The commercial logic here is worth noting. The offering does not promise primary, measured supplier data. It promises an estimated PCF that survives scrutiny — auditable, methodology-aligned, and consistent across suppliers.

That's a deliberate positioning choice. A defensible estimate, produced through a standardised pipeline, arguably beats a patchwork of supplier self-reports built on incompatible methods. For buyers facing assurance requirements under CSRD, defensibility is the product.

The obvious trade-off: estimated footprints built from emission factors and bills of materials will not satisfy every assurance standard forever. As reporting regimes tighten, primary data demands will grow.

What to watch next

Neither company disclosed commercial terms, customer names, or deployment timelines. The offering is announced and available within Sweep's supply chain module, but adoption figures and named early customers are absent.

The milestone that decides whether this matters is the enforcement calendar: CSRD reporting waves and SB253's first Scope 3 disclosure deadlines, which will show whether buyers actually convert regulatory pressure into supplier-wide PCF requests at scale.
