Mercedes-Benz reveals lifecycle CO2 data for electric GLC

Mercedes-Benz reports a two-thirds CO2 reduction for the electric GLC across its lifecycle. Explore verified data, materials, and production details in the report.

A two-thirds reduction in lifecycle carbon emissions compared to its combustion counterpart is the headline result Mercedes-Benz highlights in the environmental assessment of the new electric GLC. The figure covers the entire lifespan of the vehicle — from material extraction and production to usage over 200,000 kilometers and end-of-life processing.

The company has published its 360° Environmental Check, a detailed and independently verified report that documents the model’s environmental performance. In the case of the GLC with EQ Technology, the reduction is driven by targeted measures applied to the most carbon-intensive components: battery systems, aluminium, steel and plastics.

Production emissions alone have been reduced by 23%. Yet the battery remains the single largest contributor, accounting for around 40% of manufacturing-related emissions. To address this, Mercedes-Benz relies on cells produced using renewable energy and optimized materials for cathodes, anodes and housings. As a result, the carbon footprint per battery is lowered by approximately 40%, saving about 3.1 tonnes of CO₂.

Material choices further support the reduction. The vehicle incorporates 61 kilograms of recycled thermoplastics, including components made entirely from post-consumer sources such as end-of-life vehicle bumpers. Around two-thirds of the aluminium used comes from low-carbon production routes or recycled content, contributing an additional reduction of roughly 1.1 tonnes of CO₂. Steel produced using electric arc furnaces powered by renewable energy is also part of the material mix.

The interior marks another step: around 100 components have been certified by The Vegan Society. The vegan package extends beyond seat upholstery to include steering wheel coverings, panels, headliner and carpeting, all free from animal-derived materials and partly based on recycled inputs.

The overall environmental outcome depends heavily on how the vehicle is charged. According to Mercedes-Benz calculations, lifecycle emissions can differ by about 37% depending on whether electricity comes from the European grid mix or renewable sources. This underlines the role of the energy system in determining the real-world impact of electric mobility.

The 360° Environmental Check methodology has been used by Mercedes-Benz since 2005 and forms part of a broader strategy. The company aims to achieve carbon neutrality across its entire value chain by 2039, including suppliers and vehicle use.

With the new GLC, this strategy is reflected in a coordinated approach across all stages — from raw materials to recycling. The data suggests that consistent, system-wide adjustments, rather than isolated changes, are key to achieving substantial emission reductions.
