Siemens Mobility Reaches Record EU Taxonomy Alignment in 2025

Siemens Mobility has reported that 87% of its revenue in fiscal year 2025 is aligned with the EU Taxonomy. The figure is the company’s highest level of alignment since reporting began.

Siemens Mobility continues to expand its leadership in sustainability and has achieved a top rating in the EU Taxonomy. In its results for fiscal year 2025, the company reports 87 percent of its revenue as Taxonomy-aligned, the highest figure since the start of reporting. This confirms that the majority of Siemens Mobility’s business activities already fully meet the EU’s stringent environmental and social criteria and demonstrably contribute to the sustainable transformation of mobility. In addition, the company once again reaches 100 percent Taxonomy eligibility, demonstrating that its entire technology portfolio, from hardware to software and service offerings, can contribute to the sustainable transformation of industry and society.

Based on this foundation, Siemens Mobility reduces its own and the customers' environmental footprint worldwide, including in the areas of circular economy, sustainable water management, biodiversity protection, pollution prevention, and climate change adaptation.

EU Taxonomy Performance

"The EU Taxonomy is becoming increasingly relevant for our customers, financial actors, and public authorities. Our externally audited Taxonomy alignment rate of 87 percent underscores our leadership and shows that we are systematically embedding sustainability in our business, from product development and manufacturing to the supply chain," says Andreas Mehlhorn, Head of Sustainability at Siemens Mobility.

Sustainability Embedded Beyond Minimum Requirements

Siemens Mobility systematically integrates sustainability requirements into product development through its Robust Eco-Design methodology. Criteria such as resource and energy efficiency, the substitution of critical substances, and circularity are firmly embedded in the development processes. In parallel, the company is actively driving the use of green materials, particularly steel and aluminum, in production.

In 2025, around one-fifth of the steel volume delivered to Siemens Mobility came from the CO₂-reduced greentec steel edition produced by steel and technology group voestalpine. Additionally, in 2025, Siemens Mobility established a circular-economy ecosystem together with operators, recycling companies, suppliers, and raw-material providers to enable the reuse of critical materials and technologies at the end of their lifecycle. This consistent sustainability management, from product design to manufacturing and end-of-life treatment of rolling stock and infrastructure, goes significantly beyond the minimum requirements set by regulators and the industry, underscoring Siemens Mobility’s leading sustainability performance.

What the EU Taxonomy Measures

The EU Taxonomy is a comprehensive and transparent classification system for sustainable economic activities introduced by the European Union. The Taxonomy is employed in two steps: first, a suitability assessment (Taxonomy eligibility) is carried out to match company activities with the economic activities covered by the Taxonomy. This is followed by a compliance assessment (Taxonomy alignment) of environmental and social criteria for the activities concerned.

Relevance for Investors and Customers

For investors, the EU Taxonomy provides an additional basis to assess Siemens Mobility’s sustainability performance in comparison to other companies. Based on the externally audited indicators, capital can be channeled toward activities that contribute to the EU’s environmental objectives. At the same time, customers gain greater transparency regarding the extent to which Siemens Mobility’s products and solutions meet the EU’s requirements for sustainable economic activities.
