MAHLE has reduced its Scope 1 and 2 CO2 emissions by over 47 percent against a 2019 baseline, the German automotive supplier revealed in its Sustainability Report 2025 — published for the first time as part of its Annual Report — bringing the company within reach of its 2030 target of a 49 percent reduction.
"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."
Scope 3 emissions — covering the supply chain and product use fell by 23 percent in 2025 against the same 2019 base year. Renewable electricity accounted for 17 percent of total power consumption during the reporting year. MAHLE's German locations are carbon-neutral through green electricity supply and the offsetting of fossil fuel use.
To reduce emissions further, the company is installing what it describes as Germany's largest photovoltaic-thermal (PVT) system at its Vaihingen/Enz plant, covering nearly 21,500 sq ft. Solar installations are also operational at sites across Europe, South America, India, China, and Thailand.
For inter-company transport between its central warehouse near Stuttgart and two nearby sites, MAHLE replaced fossil diesel with the biofuel HVO100, cutting CO2 emissions on those routes by more than 90 percent. Its EV charging infrastructure arm, MAHLE chargeBIG, has installed over 300 charging points at employee parking lots across Germany.
On workplace safety, MAHLE reduced its accident rate by 19 percent in 2025 to 1.7 occupational accidents with lost workdays per one million hours worked — below the industry average and half the 2022 figure.
"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."
On supply chain governance, MAHLE joined the Responsible Supply Chain Initiative (RSCI) during the reporting year and conducts on-site audits reviewing working conditions and environmental compliance at suppliers against its Supplier Code of Conduct. The company also advanced circular product development, incorporating recycled, bio-based, and FSC-certified materials — the latter used, for example, in cabin air filter production.
