In light of the fact that the supply chain accounts for the largest share of the ecological footprint of products, the decarbonization of industry is a challenge which must be tackled by all the stakeholders together. As a leading provider of automation technology and industry software, Siemens has for the first time launched a solution for the efficient query, calculation and transfer of information on the actual Product Carbon Footprint (PCF). SiGreen now makes it possible to exchange emission data along the supply chain and combine it with data from a company’s own value creation in order to obtain a product’s true carbon footprint. To achieve this, Siemens has initiated the open, cross-industry Estainium network with the aim of enabling manufacturers, suppliers, customers and partners to exchange trustworthy PCF data. With SiGreen supporting companies in tracking their Product Carbon Footprint, they can take targeted reduction measures providing a quantifiable effect. CO2 management thus supports companies on their way towards carbon neutral production and helps them to transform sustainability into a decisive competitive edge.

鉴于供应链占产品生态足迹的最大份额，行业脱碳是一个必须由所有利益相关者共同应对的挑战。作为自动化技术和工业软件的领先供应商，西门子首次推出了有效查询、计算和传输实际产品碳足迹 (PCF) 信息的解决方案。 SiGreen 现在可以在供应链中交换排放数据，并将其与公司自身价值创造的数据相结合，以获得产品的真实碳足迹。为实现这一目标，西门子启动了开放的跨行业 Estainium 网络，旨在使制造商、供应商、客户和合作伙伴能够交换值得信赖的 PCF 数据。 SiGreen 支持公司跟踪其产品碳足迹，他们可以采取有针对性的减排措施，提供可量化的效果。因此，二氧化碳管理支持公司走向碳中和生产，并帮助他们将可持续性转变为决定性的竞争优势。

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."

西门子管理委员会成员兼数字化工业首席执行官 Cedrik Neike：“我们所有的客户都希望减少其产品的碳足迹。但要做到这一点，他们首先需要准确了解其供应链的二氧化碳排放量。他们需要知道哪些调整可以为他们节省最多的二氧化碳。SiGreen 和 Estainium 使他们能够做到这一点。它使我们能够为供应链带来急需的透明度，同时保护数据的机密性。这项技术使得我们离目标又近了一大步：行业碳中和。”

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.

精确的数据是有效实现价值链排放目标的关键前提。 西门子通过 SiGreen 成功开发了一种应用程序，用于高效获取实际产生排放的真实数据，即在供应链的相应步骤中。 为了计算碳足迹，SiGreen 使用真实数据而不是工业平均值。 产品碳足迹因此成为一种测量和控制工具——并且可以通过应用有针对性的改进措施来积极减少。

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.

供应链占产品相关排放的主要部分。 为了衡量和减少这种产品碳足迹 (PCF)，必须在经常复杂的跨行业供应链之间进行合作。 考虑到这一点，西门子启动了 Estainium 网络，用于在制造商、供应商、客户和合作伙伴之间交换产品碳足迹。

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.

其分布式账本提供高水平的数据保护：创新的分布式账本技术（DLT）支持可验证凭证的创建和交换，从而确保共享信息的可信度。所提供的数据经过验证，以便能够可靠地汇总整个供应链中的碳足迹——相关公司无需披露具有战略意义的数据，例如其自身供应链的详细信息。为了验证供应商报告的值，客户可以通过 IDUnion 区块链根据相应的凭证对他们进行所谓的可验证证明。并且由于没有集中存储发生，各方都保持完整的数据主权。与市场上可用的其他方法相比，简化与供应链中合作伙伴的沟通并优化公司自身排放量的计算可以显着减少确定二氧化碳足迹所需的工作量。
