Munich. With the new BMW 3 Series Sedan, the BMW Group is systematically extending its holistic approach to sustainability to the fully-electric variant and combustion-engine model. From the supply chain and production, through to the use phase and recycling, key levers have been optimised with the aim of reducing the CO₂e footprint throughout the vehicle lifecycle. The Bavarian production cluster plays an important role in this: Plants Dingolfing, Landshut, Irlbach-Straßkirchen and Munich bring together core expertise, reduce transport distances and efficiently integrate specialised production steps.

Focus on supply chain decarbonisation

The supply chain is a key lever for reducing CO₂e emissions. In this area, the BMW Group relies, in particular, on renewable energy and higher secondary material content, as well as product and process innovations. The measures are systematically applied to all drive train variants of the new BMW 3 Series. Already during the product development phase, supply chain CO₂e emissions were reduced by around 37 percent for the BMW i3 and by around 30 percent[1] for the variant with an internal combustion engine. A particular focus is on battery cells and the use of aluminium.
The Gen6 battery cells for the BMW i3 rely on secondary materials for a portion of their cobalt, lithium and nickel. The BMW Group also uses renewable energy in the production of anode and cathode materials, as well as in cell manufacturing. In comparison with the Gen5 cell in the BMW i4, the CO₂e footprint per watt-hour was reduced by approx. 33 percent.

Systematic use of secondary materials

Measures implemented in the supply chain and at the company’s own facilities enable a high secondary material content in the new BMW 3 Series – also for heavy-duty components. These include aluminium suspension components such as wheel rims, swivel bearings and wheel supports, which rely on electricity from renewable sources for both electrolysis and production. Secondary material is also used for the car body: The bonnet is made of approximately 70 percent recycled aluminium. In the battery-electric BMW i3 50 xDrive, around 31 percent of the total vehicle consists of secondary materials; in the BMW 3 Series with internal combustion engine, the share is around 25 percent[1].

BMW Group sites combine sustainability with specialisation

The Dingolfing, Landshut, Irlbach-Straßkirchen and Munich facilities pool core expertise within the Bavarian production cluster. Short transport distances and closely integrated processes unlock potential for reducing CO₂e emissions.

“The cluster approach to BMW production is directly linked to the concept of sustainability: Short distances and close proximity are key characteristics of a cluster, creating direct economic, environmental and social sustainability benefits through regional networking and concentration. A regional production cluster, like at BMW, creates added value for the economy, people, the environment and, of course, the region,” explains Prof Dr Rudolf Juchelka, Chair of Economic Geography, especially Transport and Logistics at the University of Duisburg-Essen.

Landshut: Light metal and components expertise

BMW Group Plant Landshut is the company’s largest component plant worldwide and a centre of in-house manufacturing expertise. The light metal foundry produces parts for electric drive trains, as well as engine components such as crankcases and cylinder heads. For the new BMW 3 Series, the facility is also manufacturing the e-drive housing for the rear axle of the fully-electric variant, alongside crankcases and cylinder heads for the combustion-engine model. The corresponding drive trains are produced at BMW Group Plant Steyr in Austria, which has been a source of drive train expertise within the production network for over 40 years.

The Landshut site combines long-standing aluminium and foundry know-how with specific sustainability measures, such as using aluminium from recycling loops and material produced in part with electricity from renewable sources. In-house component manufacturing strengthens material expertise, conserves resources and supports close integration of production processes.

Irlbach-Straßkirchen: “Local for local” high-voltage batteries

Construction of the new assembly site for sixth-generation high-voltage batteries at Plant Irlbach-Straßkirchen got underway in spring 2024. In line with the “local for local” principle, the plant will supply high-voltage batteries for the BMW i3 from October 2026. This strengthens regional structures, reduces transport distances and helps secure jobs. At the same time, close cooperation between the German pilot plants and series production facilities worldwide supports the global production network. Key components for the BMW i3 will be manufactured close to vehicle production and transported to Munich on electric trucks.

The plant requires no fossil fuels for regular operations. A photovoltaic system generates a share of the electricity required directly on site. All additional energy needed is supplied entirely from renewable sources. The process is designed so that no water is required for assembling the high-voltage batteries. In this way, the site is combining the industrialisation of electromobility with lower emissions and resource-efficient production.

Munich: Transformation towards the BMW iFACTORY

BMW Group Plant Munich produces vehicles for the Neue Klasse, following the principles of the BMW iFACTORY, with a focus on efficiency, digitalisation and sustainability. The site obtains all the external power it requires from renewable sources. The plant is also committed to responsible use of resources – for example, through the material loop in the press shop: Steel and aluminium scrap generated while punching body parts is collected and separated by material type, recycled and subsequently used to manufacture new coils.

Dingolfing: Renewable energy and process heat

BMW Group Plant Dingolfing combines efficient production processes with close integration with the surrounding component sites. All purchased electricity comes from renewable sources, with a portion generated directly on site. Since late 2025, a photovoltaic system on the plant's roof, with a capacity of just under 11 megawatt peak, has supplied electricity for the site.

A new biomass heating plant west of the vehicle plant also provides up to 100,000 megawatt hours of locally-produced heat from renewable energy sources. In this way, the facility can meet about half of its process heat requirements.

Efficiency during use phase

With its EfficientDynamics technology package, the BMW Group optimises vehicle efficiency across all relevant subsystems. This includes aerodynamics, lightweight construction, low rolling resistance tyres and overall energy management. EfficientDynamics has been used by the BMW Group across all drive technologies since 2007. The new fully-electric BMW i3 also features the “Heart of Joy”, with the fully in-house developed BMW Dynamic Performance Control Driving Stack. The system enables effortless and confident drivability, with highly controlled deceleration to a standstill. At the same time, it enhances efficiency: During deceleration, more energy is recovered through recuperation – in significantly more driving situations, right down to a standstill. Gen6 drive technology components are also systematically optimised for efficiency.

Using so-called SiC technology in the electric drive units, it was possible to reduce energy losses by up to 40 percent.

Transparency through TÜV-verified Product Carbon Footprint

The BMW Group will publish the Product Carbon Footprint for the BMW 3 Series, validated by the German Technical Inspection Association (TÜV), to coincide with the series launch. The report, including the underlying calculation methodology and methods, will be publicly available. In this way, the BMW Group creates transparency around the raw materials used and CO₂e emissions throughout the vehicle’s entire lifecycle.

The Product Carbon Footprint for individual components and materials is calculated in accordance with the Catena-X rules. The data ecosystem enables standardised data exchange, with traceability of emissions data throughout the value chain – from the extraction of raw materials to the end product.

Steyr. BMW Group Plant Steyr is switching entirely to district heating for warmth: in regular operations the Austrian engine facility now no longer uses natural gas, relying instead on heat from a nearby biomass powerplant. In a symbolic act, Milan Nedeljković, Board Member for Production at BMW AG, and Arnold Schwarzenegger turned on the new power supply. The change of energy source marks yet another step in the BMW Group’s efforts to reduce its carbon footprint.

Milan Nedeljković, member of the Board of Management of BMW AG responsible for Production: “We are optimising the carbon footprint of all our production facilities worldwide, using innovative technologies and the potential of the local area to generate energy from fossil fuel-free sources. Today, we are setting a new milestone here in Steyr.”

Consistent reductions in energy consumption

BMW Group Plant Steyr uses around 250 gigawatt hours of energy a year – enough to power about 59,000 homes. Over the last few years, energy consumption has fallen steadily: “Since 2006 we have succeeded in almost halving the amount of energy we use per engine,” explained Plant Director Klaus von Moltke.

Heat supplies play a particularly important role in all of this: “The plant was first connected to the district heating grid in 2012. Since then, there have been multiple expansions,” Klaus von Moltke continued. The transition to purely district heating was expected to reach completion at the turn of the year 2024-2025 but has now been realised two and a half months earlier.

Where the heat comes from: regional district heating from wood chips

The switch would not have been possible without a strong partner in the region: BMW Group Plant Steyr now sources its heat from the biomass powerplant of Fernwärme Steyr, just under a kilometre away. This is operated by the state’s two energy providers – Energie AG Oberösterreich Erzeugung GmbH and EVN Wärme GmbH – in their joint subsidiary, Bioenergie Steyr GmbH. To provide the heat energy that Plant Steyr needs, an additional heat generation plant with a 10-megawatt biomass boiler is being erected at the site. So, Plant Steyr will source its heat from renewable resources: wood chips from the surrounding forests.

Klaus von Moltke summarised the situation saying: “By switching to 100 percent heat from regenerative biomass, we are taking a major step today. Our plant now sources both its electricity and its heat for regular operations from renewables.”

Today’s symbolic energy switch took place on stage as more than a thousand employees looked on. In his keynote speech Arnold Schwarzenegger called on everyone present to act on climate change. He then shut down the plant’s gas supply. Milan Nedeljković, Board Member for Production at BMW AG, then symbolically turned on the final expansion to the district heating supply.

Arnold Schwarzenegger then joined Klaus von Moltke and Milan Nedeljcović for a tour of the training and education centre, engine assembly and BMW Group Plant Steyr’s recently opened electric motor production line, chatting with employees as he went.
