At BMW Group Plant Debrecen, the paint shop plays a critical role in significantly reducing the CO2e footprint of the BMW iX3. Production of the new BMW iX3 will generate a total of about 80 kg CO₂e (scope 1/2 emissions). This figure covers CO₂e emissions from Plant Debrecen, as well as in-house parts production at other BMW Group facilities, including components manufactured in Landshut, for example. This represents a reduction of approx. two-thirds compared to production of existing BMW derivatives. For Plant Debrecen alone, this approach will reduce CO₂e emissions from the manufacture of a vehicle, including its high-voltage battery, by around 90% – to about 34 kg CO₂e (when operating at full capacity, compared with other BMW Group facilities).
Paint shops typically rely on gas to reach the high temperatures (up to 180 degrees Celsius) required. Plant Debrecen will be the BMW Group's first car plant supplied exclusively with electricity from renewable energy sources during normal operation, i.e. without using fossil fuels such as oil or gas. Because of its high energy demands, the paint shop is the most important factor in significantly lowering Plant Debrecen’s CO2e emissions. In the paint shop alone, using electricity from renewable sources reduces annual CO2e emissions by up to 12,000 tonnes. About a quarter of the plant's annual power needs will be supplied by the 50‑hectare on-site photovoltaic system. Surplus solar energy, such as that generated on non‑working days, is stored in a 1,800 m³ thermal storage system with a capacity of 130 MWh.
