Press Release22 November 2021Digital IndustriesNuremberg
Siemens has developed an ecosystem-based approach for the exchange of emission data
Cedrik
Neike, Member of the Managing Board of Siemens AG and CEO Digital Industries: "All
our customers share the desire to reduce the carbon footprint of their
products. But to do so, they first need to know exactly the CO2 emissions of
their supply chain. And they need to know which adjustments can save them the
most CO2. SiGreen and Estainium enable them to do just that. It allows us to
bring much-needed transparency to supply chains while protecting the
confidentiality of the data. This technology can bring us a big step closer to
our goal: a carbon neutral industry."
Precise
data is a key prerequisite for effectively achieving the emission targets in
the value chain. With SiGreen, Siemens has successfully developed an
application for the efficient acquisition of real data collected where
emissions are actually produced, i.e. in the corresponding steps along the
supply chain. To calculate the carbon footprint, SiGreen makes use of real data
rather than industrial average values. Product Carbon Footprints thus become a
measurement and control instrument – and can be actively reduced by applying
targeted improvement measures.
The supply chain accounts for a major proportion of
product-related emissions. To measure and reduce this Product Carbon Footprint
(PCF), cooperation across frequently complex, cross-industry supply chains is a
must. With this in mind, Siemens has initiated the Estainium network for
the exchange of Product Carbon Footprints among manufacturers, suppliers,
customers, and partners.
Its
Distributed Ledger provides a high level of data protection: The innovative
Distributed Ledger Technology (DLT) supports the creation and exchange of
Verifiable Credentials, thus ensuring the trustworthiness of the information
shared. The data provided is verified in order to enable the trustworthy
aggregation of a carbon footprint across the supply chain – without the
companies involved having to disclose data of strategic relevance, for example details
of their own supply chains. To verify the values reported by a supplier,
customers can subject them to a so-called Verifiable Proof against the
corresponding Credential via the IDUnion blockchain. And since no centralized
storage takes place, each of the parties maintains full data sovereignty.
Simplifying the communication with partners in the supply chain and optimizing
the calculation of a company’s own emissions can significantly reduce the
effort required to determine a CO2 footprint compared to other approaches
available on the market.
Background information:
The transition towards a low carbon economy is gaining
momentum worldwide. Most companies today measure their energy-related emissions
– and an increasing number of them is pursuing emission reduction measures. The
decarbonization of value chains is a challenge which cannot be overcome by one
company alone. In fact, the upstream supply chains account for a major part of
the Product Carbon Footprint, rather than a company’s own manufacturing
process. Suppliers produce so-called Scope 3 emissions – and quantifying these
emissions is of critical importance. Collecting precise and trustworthy
information on the emissions originating from a company’s partners in the
supply chain requires considerable effort in today’s world. Alternative
solutions based on third-party database values or calculations are both
cost-intensive and require the disclosure of strategically relevant
information, as well as its storage by third parties. However, none of these
solutions is suitable for fulfilling customer demands for PCFs on a large
scale. To address this issue, Siemens has developed an ecosystem-based approach
for the exchange of trustworthy product emission values. As recommended by
leading NGOs (WRI, GHG Protocol, and GIZ), it is based on a Distributed Ledger.
In contrast to existing solutions, the data is not stored centrally by a
company or institution. Instead, it is exchanged directly within the scope of
customer-supplier relations. Verifiable Credentials issued by trusted third
parties are exchanged via a Distributed Ledger in order to verify the data
provided – and to enable the trustworthy aggregation of an overall Product
Carbon Footprint across the supply chain without compromising the partners’ need
for supply chain confidentiality.
