At ESTAINIUM, four different working groups are working on the realization of the project to make the world a better place.

Technology and Infastructure

The first working group is selecting and developing the basic technical infrastructure which is needed for the exchange of product related footprints.

  • Education of stakeholders on use cases of inter- and intra-company
    execution of sustainability
  • Alignment on common principles to allow for interoperability
  • Alliance of sustainability thought leaders across industries,
    NGOs and certifiers
  • Governs the ecosystem as an independent cross-company body
  • Initial tech-stack donated as open source by Siemens to kick-start activities

Standards and Norms Compatibility

The second working group is focused on simplifying the navigation in the increasingly complex landscape of PCF standards, norms, and sector or product specific guidance.

  • PCF specific requirements for verifiable exchange mechanism of ESTAINIUM
  • One PCF data model for verifiable data structure of the ESTAINIUM infrastructure which is interoperable with all member networks
  • Standards and sharing network compatibility services based on guidance material & conversion logics for member applications
  • Gap filling alignments, - work item proposal which is case studies driven

Carbon Capture,
Use, Storage & Compensation

The third working group is developing guidelines to integrate high quality carbon removal projects in accounting mechanisms and product lifecycle management.

  • Offset specific requirements for verifiable exchange mechanism
  • Access to the development of a holistic marketplace framework for full usability, transparency and visualization processes
  • Selection and comparability between relevant sink technologies for the implementation of operations in industry
  • Definition of a future industry standard for quality assurance in own supply chains with „approved by ESTAINIUM” certification



The fourth working group “Regulation” is focused on giving guidance in the complex landscape of carbon regulation. This comprises the international, the regional, the national and if applicable also the local scale.

  • The working group functions an internal service provider for the ESTAINIUM working groups 1-3, but also as a think tank which will publish guidance for everyone who is concerned
  • Among the top priority topics are the EU’s Carbon Border Adjustment Mechanism (CBAM), the regulatory framework for a product pass that includes carbon footprint information, and the evolving CDR and certificates regulation
  • ESTAINIUM Working Group 4 will also give guidance on publicly available information and sources on carbon regulation to support companies to find a path through the complex landscape of carbon regulation
