Carbon Reduction @ Suppliers program

We are committed to achieving a 20% CO₂e reduction by 2030 and a net-zero supply chain by 2050. To lead by example, we recognize that collaboration with our suppliers is essential. We focus on close collaboration and engagement with you. With joint forces, we approach this with our Carbon Reduction @ Suppliers program (CR@S). This is our comprehensive approach to support you in your target setting and action plans for reducing your carbon footprints.

We collaborate with an external partner, ctrl+s. ctrl+s hosts the external carbon management platform supplier+s. The Siemens Supply Chain Management (SCM) and Procurement community invites selected suppliers to complete the carbon web assessment (CWA) on supplier+s. The CWA enables you to learn about your own carbon emissions and document the implementation of reduction measures. By completing the different chapters of the self-assessment, you share your decarbonization plans with us, providing the basis for collaborating towards a net-zero supply chain.

Assess your decarbonization efforts

The carbon web assessment (CWA) is an online self-assessment for suppliers, available in the platform supplier+s. The CWA contains up to 19 questions on current and planned decarbonization efforts. It consists of two sections, namely “Company questions” and “Business segments”. Under the section "Company questions" you should provide answers on your corporate targets, footprints and achieved reductions. Under the section "Business segments" you are asked about your specific processes, products and services (e.g., used metals, basic chemicals, transport equipment).

Tracking your CO₂e emissions

Carbon accounting involves measuring, tracking, and reporting an organization’s carbon emissions. This process helps you gain a comprehensive view of your carbon footprint, including emissions across different scopes, supply chain inputs, and your own suppliers. As part of the Carbon Reduction @ Suppliers program, the carbon accounting module allows you to prioritize your decarbonization efforts. We encourage our nominated suppliers to use this voluntary module in supplier+s, which helps you identify emission hotspots and areas for improvement. To further manage your carbon emissions, you can invite your own suppliers to join them on their decarbonization journey via supplier+s. This collaboration helps identify the most relevant suppliers and their share of emissions, without needing to disclose detailed supply chain information.

Decarbonization isn’t one-size-fits-all
