Mercedes-Benz says the all-new electric C-Class generates two-thirds less carbon across its full lifecycle than the combustion-powered C-Class currently in production. The figure comes from the company’s 360° Environmental Check for the model, a lifecycle assessment the automaker states is verified by independent auditors. Mercedes-Benz reports that supply chain emissions alone fall by approximately 23 percent, drawing on sustainability measures the company first introduced with the all-new electric GLC.
Highlights
- Two-thirds reduction in lifecycle carbon footprint versus the combustion-engine C-Class, per an independently audited assessment
- Approximately 23 percent lower supply chain CO₂ emissions through carbon-reduced aluminum, steel, plastics and battery cells
- 473 miles (762 km) WLTP range, with up to 202 miles (325 km) recovered in ten minutes of DC fast charging
- 42.3 MWp of installed photovoltaic capacity at the production site, covering roughly a quarter of its annual energy demand
Where Do the Supply Chain Savings Come From?
The company attributes the 23 percent supply chain reduction to carbon-reduced input materials negotiated with suppliers. Roughly two-thirds of the vehicle’s aluminum comes from electrolysis plants running on renewable energy or carrying an increased share of recycled material, according to Mercedes-Benz, covering the body, steering knuckles, wheels and battery housing. Approximately 99 pounds of steel sourced from electric arc furnaces powered by renewable energy goes into components manufactured in-house.
Secondary material content in thermoplastics has increased more than fourfold against the combustion C-Class, the company says, totaling approximately 108 pounds of recycled thermoplastic per vehicle. Components with recycled content include:
- Frunk tub — 50 percent post-consumer recycled material
- Wheel arch liners — 93 percent recycled content
- Jack mounts — made from 100 percent recycled bumpers taken from scrap vehicles
- Bumper carriers — 83 percent recycled content
- Seat cover nonwoven fabric and yarn — 34 and 50 percent recycled content, respectively
Mercedes-Benz describes the underlying framework as “Design for Environment,” an approach it says weighs material efficiency, recyclability and secondary raw material use during early development.
Use-Phase Efficiency
The electric C-Class carries up to 473 miles (762 km) of WLTP range, with combined energy consumption rated at 29.8–22.7 kWh per 100 miles (18.5–14.1 kWh/100 km) on the same cycle. WLTP figures are typically higher than EPA ratings, and North American numbers for the model have not been published.
An 800-volt architecture underpins both efficiency and DC charging speed. A multi-source heat pump comes standard, drawing waste heat from the drive system and battery alongside ambient air; Mercedes-Benz states it requires around one-third of the electrical energy a comparable electric auxiliary heater would need for equivalent heating output under the same conditions. The car uses a new One-Box braking system, and the company reports that up to 99 percent of braking events are handled entirely through recuperation, which is possible at up to 300 kW.
On charging, Mercedes-Benz cites up to 202 miles (325 km) of range added in as little as ten minutes, measured at maximum DC charging power under ISO/SAE 12906 conditions. Standard MB.CHARGE Public access covers more than 3 million charging points. Where renewable electricity is not available at a given station, the Renewable Charging component uses Energy Attribute Certificates, including the EKOenergy eco label, to feed an equivalent amount of renewable energy into the grid.
Production at Kecskemét
The model is built at the Kecskemét plant in Hungary. A ground-mounted solar park west of the site carries an installed capacity of 27.4 MWp across more than 2.5 million square feet; combined with rooftop arrays on the battery assembly facility, body shop and assembly halls, total capacity reaches 42.3 MWp, which the company says can cover approximately 25 percent of annual energy demand. In the new paint shop, Mercedes-Benz reports optimized processes cut energy consumption by roughly 20 percent and carbon emissions by roughly 80 percent against the existing facility.
Supply Chain Governance and Interior Materials
Suppliers must accept the Responsible Sourcing Standards, the company’s contractual framework covering working conditions, human rights, environmental protection and business ethics. Binding CO₂ reduction targets are embedded in sourcing processes for steel, aluminum, plastics and battery cells. Mercedes-Benz says it aims to complete due diligence assessments of all material high-risk raw materials by 2028, with progress disclosed in its Raw Material Report.
The C-Class also offers an optional vegan interior independently certified by The Vegan Society, covering seat upholstery, headliner, door and pillar trim, and carpets. According to the company, the electric GLC is the only other vehicle worldwide holding that certification. All soft-touch interior surfaces — microfiber fleece, textiles and MB-Tex — were reviewed and audited, with any animal-derived components replaced through supplier development work.
Mercedes-Benz has published product-specific environmental data since 2005, with each 360° Environmental Check based on a full vehicle lifecycle assessment and confirmed by independent auditors.
