Polestar 4 life cycle

Material production

From aluminium and steel to plastics, each material category contributes to Polestar 4’s overall carbon footprint, as does the electricity mix used in material production and refining. We aim to continuously reduce the carbon impact and the accuracy of our footprint calculations.

Li-ion battery modules

Factors in the battery’s carbon footprint calculation range from mining operations, to the energy used for cell production, to the aluminium in the battery casing. We aim to further reduce battery carbon footprint with future models and iterations of Polestar 4.

Manufacturing

Polestar 4 is produced at Hangzhou Bay in China. The Hangzhou Bay plant is a key component of our sustainability strategy, and is powered by 100% renewable electricity.

Use phase

On the road, Polestar 4 drivers can significantly reduce the car’s overall carbon footprint by charging it with renewable energy sources such as solar or wind.

End-of-life

The vast majority of materials used to manufacture Polestar 4 are recyclable at the end of the car’s lifespan. Batteries can be dismantled and shredded into powder, allowing minerals to be recovered and reused in the manufacture of new batteries.

Cradle-to-gate carbon footprint

Circularity

Polestar 4 represents another step on the journey towards circularity. Some textiles are made using recycled materials, with others designed to be recycled at the end of their lifecycle.

Material innovations

Tailored Knit

The yarn used in Polestar 4’s optional interior upholstery is made from 100% recycled PET bottles. Knitted to size, the fabric minimises waste without compromising look and feel.

Material innovations

Bio-attributed MicroTech

Polestar 4’s optional interior upholstery uses a vegan alternative to leather. Bio-attributed MicroTech contains 25% bionaphtha, 14% recycled polyester textile, 33% plasticiser and 28% chlorine. The bio-attributed PVC (which makes up 53% of the MicroTech fabric) has 70% lower CO₂ emissions than conventional PVC.

Recycled materials

Textiles and plastics

Reycled plastics have a variety of uses inside Polestar 4. For example, inlay carpets are produced using recycled PET mono-material, and base floor carpets include reclaimed fishing nets. We aim to make as many plastic parts as possible from recycled plastics.

Recycled materials

Steel

Polestar 4 parts including the body, subframe, brake parts and seats make use of recycled steel from post-consumer and post-industrial waste.

Traced materials

Tracing raw materials is a major step towards achieving more responsible sourcing and production. We constantly assess the balance between quality, efficiency, and material use. While certain materials come with associated risks, they can lead to more durability or better performance and battery efficiency.

Nappa leather

Perforated Nappa leather upholstery is produced using hide from farms in countries that are independently rated by the Animal Protection Index as being of the highest global standard. It is chrome-free and traceable via a process that controls and monitors the farms and tanneries from which the leather originates.

3TG conflict minerals

Tin, tantalum, tungsten and gold (3TG) are so-called conflict minerals with a wide range of uses in EVs. In politically unstable regions, the mineral trade sometimes finances armed groups, fuels forced labour and sustains corruption and human rights abuses. The 3TG minerals we use are traced via Conflict Mineral Reporting, which verifies that smelters conform with the Responsible Minerals Assurance Program (RMAP).
