Sustainable and responsible business practices are an integral part of the MAHLE corporate strategy. This is underlined by the recently published Sustainability Report 2025, which the Group has presented for the first time as part of its Annual Report. The automotive supplier is ahead of schedule in meeting its climate targets, with continued progress in emissions reduction. MAHLE has cut its CO? emissions from electricity and fuel consumption (Scope 1 and 2) by nearly half to date. The 2030 target is now within reach. During the reporting year, MAHLE intensified its commitment to an ethically responsible and sustainable supply chain. In addition, the Group advanced sustainable product development through the increased use of circular and bio-based materials. MAHLE also achieved significant success in strengthening its occupational safety activities. The number of accidents involving lost workdays has been cut in half since 2022, and the company's accident rate is below the industry average.
"With the integration of our sustainability report into the annual report for the first time, MAHLE emphasizes the importance of sustainability for the company's future strategic direction," said Georg Dietz, Member of the MAHLE Group Management Board responsible for Sustainability, Occupational Safety and Environmental Management. "MAHLE is on track in pursuing its objectives. We are particularly pleased with the significant progress achieved in the area of workplace safety in 2025."
Last year, MAHLE reduced its accident rate by 19 percent to 1.7 occupational accidents with lost days per 1 million hours worked. This positive trend is also reflected in several awards from external organizations that have honored MAHLE locations for their outstanding performance in the area of occupational health and safety.
Multiple Levers for Decarbonization
"We have significantly sharpened awareness for sustainable and responsible behavior across the entire company," said Kathrin Apel, Director Corporate Sustainability and Occupational Health, Safety and Environmental Management at MAHLE. "This ranges from the resource-efficient use of energy and materials to the integration of sustainability aspects into decision-making in development, purchasing, and production."
Scope 1 and 2 CO? emissions from production and energy sourcing have been reduced by over 47 percent compared to the base year 2019 - so we are just under two percentage points away from the 2030 target of 49 percent. Scope 3 emissions from the supply chain and product use decreased by 23 percent in 2025 compared to the same base year.
The company is consistently expanding its CO? reduction activities by leveraging a wide range of technologies. Renewable electricity accounted for 17 percent of total power consumption in 2025. MAHLE locations in Germany are carbon-neutral, thanks to green electricity supply and the offsetting of fossil fuel use. One of the company's plants in Mogi Guacu became the fourth site in Brazil to enter into a green electricity supply agreement in 2025. Multiple MAHLE locations across Europe, South America, India, and China - including Guangzhou, Shanghai, and Shenyang - as well as Samut Prakan in Thailand, are powered by modern photovoltaic systems.
MAHLE is currently installing what is presently Germany's largest photovoltaic-thermal (PVT) system at its plant in Vaihingen/Enz (Germany) covering an area of nearly 21,500 sq ft, providing climate-friendly electricity and heat supply.
The expansion of EV charging infrastructure at MAHLE continues at full pace: MAHLE chargeBIG has now installed over 300 charging points at employee parking lots at numerous plants across Germany.
For inter-company transport between the MAHLE central warehouse near Stuttgart and the Muehlacker and Vaihingen sites, fossil diesel has been replaced with the biofuel HVO100, enabling savings of more than 90 percent in CO? emissions.
MAHLE develops materials that enable resource conservation and CO? reduction over the entire product life cycle. Among others, FSC-certified (Forest Stewardship Council) materials are applied, for example in the production of cabin air filters for vehicles.
Responsible Supply Chains Worldwide
By joining the Responsible Supply Chain Initiative (RSCI), the automotive supplier emphasizes its commitment to transparent procurement processes. The company conducts on-site audits at its suppliers and consistently reviews working conditions as well as environmental aspects. The improved supplier transparency ensures compliance with the standards set out in the MAHLE Supplier Code of Conduct.
