Makersite to Acquire Siemens’ SiGREEN Platform as June 2026 Deal Expands PCF and Scope 3 Data Exchange Across Global Supply Chains

Makersite has announced that it will acquire Siemens’ SiGREEN platform effective June 1, 2026, adding a well-established product carbon footprint and supply chain data exchange system to its product lifecycle intelligence software stack. The company said the deal will combine SiGREEN’s verified emissions data exchange capabilities with Makersite’s existing tools for environmental analysis, regulatory compliance, and product decision-making.

The transaction matters because it expands Makersite’s position from product-level sustainability analysis into a more direct role in supplier carbon data exchange. That is increasingly important for manufacturers facing pressure to calculate product carbon footprints more accurately, support audit-ready Scope 3 reporting, and exchange emissions data across multi-tier supply chains rather than relying only on estimates or static datasets. This interpretation is an inference based on the capabilities described by Makersite and the role SiGREEN already plays in industrial supply-chain carbon data exchange.

 

SiGREEN brings a strong position in cross-company PCF exchange

 

According to the announcement, SiGREEN is already used to collect, manage, and exchange product carbon footprint data between companies and suppliers globally. Makersite says the platform currently powers the Together for Sustainability PCF Exchange, connecting a significant share of the global chemical industry and its supplier base, and is also active in industrial and automotive use cases. The company further states that SiGREEN is the only platform of its kind that natively connects the TfS, Catena-X, and PACT frameworks, allowing companies to exchange verified carbon data even when their ecosystem partners operate under different standards.

That interoperability point is one of the strongest parts of the deal. In Scope 3 and PCF reporting, one of the biggest bottlenecks is not only collecting emissions data, but making it usable across different frameworks, suppliers, and customer expectations. By acquiring a platform already built around multi-framework exchange, Makersite is strengthening its ability to serve companies that need more than internal lifecycle analysis. They also need trusted supplier-facing data infrastructure. This is an inference based on the framework connectivity highlighted in the announcement.

Continuity and trust are central to the handover

 

Makersite says all SiGREEN and TfS Data Exchange Platform services will continue without interruption during and after the ownership transfer. It also says data security, privacy, and platform integrity will remain top priorities, and that company administrators will receive guidance and support before and after the June 2026 transfer. The company added that it is working with Siemens, the TfS Secretariat, and the TfS Scope 3 GHG Workstream to ensure a smooth transition.

This emphasis on continuity is important because carbon data exchange platforms depend heavily on trust between buyers and suppliers. A transition in ownership can create uncertainty around governance, access, and data protection, especially when the platform supports sensitive supply-chain emissions information. Makersite’s messaging suggests it understands that preserving user confidence may be as important as the technical integration itself. That conclusion is an inference based on the transition commitments stated in the announcement.

 

The deal extends an existing Siemens-Makersite relationship

 

The acquisition also builds on an earlier collaboration between Siemens and Makersite. In July 2025, Makersite announced a cooperation with Siemens Digital Industries Software to integrate its environmental, cost, and supply-chain risk data directly into Teamcenter. That earlier partnership already signaled alignment between the two companies around sustainability intelligence inside product lifecycle workflows. The SiGREEN acquisition now pushes that relationship further by transferring ownership of a key carbon data exchange platform into Makersite’s ecosystem.

Seen together, the two steps suggest Makersite is trying to build a more complete sustainability infrastructure layer for manufacturers. Instead of offering only lifecycle analysis inside PLM environments, it is adding upstream supplier emissions exchange capability that can support PCF calculation and Scope 3 reporting more directly. This is an inference based on the 2025 Teamcenter collaboration and the 2026 SiGREEN acquisition announcement.

What the deal signals

 

The broader significance of the acquisition is that sustainability software for manufacturers is moving toward connected data systems rather than isolated analysis tools. Companies increasingly need lifecycle assessment, regulatory compliance, product carbon footprints, and supplier emissions exchange to work together as one operating layer. Makersite’s acquisition of SiGREEN points in exactly that direction.

For manufacturers, the likely value is clearer access to verified supplier data and better support for audit-ready product and Scope 3 reporting. For the market, the deal suggests that trusted carbon data exchange is becoming a strategic software capability in its own right, not just an add-on to sustainability reporting. This final point is an inference based on the role SiGREEN plays today and the use cases Makersite highlights.
