360° Environmental Check for the all-new electric GLB: 21 % less CO₂ in the supply chain and up to 2.8 tonnes of CO₂ saved in the battery cells achieved by reduction measures

• CO₂-reduction in the supply chain of around 21 % – achieved through the use of renewable electricity and recycled materials in key components and materials such as batterie, aluminium, steel and thermoplastics – compared to production without these measures
• Up to 2.8 tonnes of CO₂ savings in the battery cells through the use of renewable energy
• More than 50% of the aluminium (163 kg) comes from CO₂-reduced production using renewable energy, resulting in savings of around 0.6 tonnes of CO₂

Mercedes-Benz is consistently advancing the decarbonisation of its compact segment: the all-new electric GLB sets a benchmark for a more sustainable production and a CO₂-reduced supply chain with its 360° Environmental Check. The analysis, verified by independent auditors, highlights significant progress, particularly in manufacturing – one of the most important levers for reducing emissions.

The key result: CO₂-emissions can already be reduced by around 21 % during the production phase by taking specific reduction measures. This is made possible by close collaboration with suppliers, as well as the targeted use of renewable energy and CO₂-optimised materials.

Consistently engineered for CO₂ reduction across the entire value chain

The new GLB is based on the new Mercedes‑Benz Modular Architecture (MMA). Designed from scratch with a focus on decarbonisation and circular economy principles, particular attention has been paid to especially emission-intensive components and materials such as the battery, aluminium, steel and thermoplastics, which are at the centre of the reduction measures.

Key contributors to the environmental performance at a glance:

• CO₂-reduced high-voltage battery: The use of electricity from renewable sources in cell production reduces the carbon footprint of the battery cells by around 40 %. Across the entire battery, this corresponds to a saving of approximately 2.8 tonnes of CO₂.
• Sustainable aluminium: More than half of the aluminium used (163 kg) comes from smelters powered by renewable energy. This reduces the carbon footprint of these components by around 30 % – amounting to a total saving of approximately 0.6 tonnes of CO₂.
• Transformation of steel production: Steel and ferrous materials account for around 46 % of the materials used. The GLB already incorporates approximately 20 kg of CO₂-reduced steel produced in electric arc furnaces powered by renewable energy. Looking ahead, the combination of direct reduction with green hydrogen usage and electric steelmaking processes has the potential to enable virtually CO₂-free steel production.
• More recycled materials for lower emissions: A total of 45 kg of thermoplastic recyclates are used. Examples include:
  – Frunk tub: 50 % recycled content
  – Jacking points: 100 % made from recycled material
  – Longitudinal member claddings and bumper substructures: up to 30 %
  These measures alone result in savings of around 71 kg of CO₂ compared with the use of primary materials while promoting a circular economy at the same time.

Net carbon-neutral¹ production at the Kecskemét plant

Since 2022, Mercedes-Benz’s own vehicle production sites have been net carbon-neutral¹. By 2030, more than 70 % of energy requirements in production are set to be covered by renewable energy. The goal for all Mercedes-Benz production plants worldwide is to operate entirely on renewable energy without CO₂ emissions by 2039. As part of ongoing construction measures, Mercedes-Benz is investing in the expansion of photovoltaic systems across the entire Kecskemét site. In addition, there is a strong focus on the continuous reduction of water consumption and waste volumes.

About the 360° Environmental Check

Mercedes‑Benz has published product-specific environmental information since 2005. The 360° Environmental Check is based on a comprehensive lifecycle assessment of each vehicle and verified by independent auditors. This transparency initiative reflects Mercedes‑Benz's commitment to helping customers make informed purchasing decisions.

^[1]Net carbon-neutral means that carbon emissions that have neither been avoided nor reduced at the Mercedes-Benz Group are compensated for by certified offsetting projects.

Mercedes-Benz Anniversary Year “140 Years of Innovation”

Since Carl Benz filed the patent for the first automobile 140 years ago and Gottlieb Daimler built his motorised carriage shortly afterwards, Mercedes‑Benz has dedicated itself to constant innovation and to creating the world’s most desirable cars for customers. This ambition has driven every innovation – from the world's first automobile in 1886 to the biggest product launch programme in the company’s history that is currently underway. With its passion for performance and pioneering power, excellence and an unwavering commitment to customer service, the brand has consistently shaped the future of mobility. The result goes well beyond engineering achievement – it creates the unmistakable feeling that leads through everything Mercedes‑Benz does: Welcome home.

Mercedes-Benz is celebrating 140 years of innovation by driving three new S-Class saloons on a trans-continental journey to 140 locations worldwide. Each place highlights the brand’s technology, heritage, pioneering spirit and worldwide presence. Along the way customers, fans and colleagues will get to join in the celebrations - on an epic adventure that will run until October. Follow the “140 Years. 140 Places” drive across six continents on our “140 years of innovation | Mercedes-Benz Media” special and via the Mercedes-Benz Community.
