For automakers who’re below intense regulatory and social stress to scale back their carbon output, sustainability is about extra than simply emissions. Most automotive firms are in search of methods to scale back air pollution in each space from manufacturing to supplies selections and past. And now Volvo-adjacent electrical efficiency model Polestar says its new Polestar 4 crossover coupe is a carbon-fighting beast.
Polestar has been moderately clear to this point on the emissions and sustainability entrance. Now that the first Life Cycle Evaluation (LCA) for the Polestar 4 has been revealed, it reveals the EV has the bottom carbon footprint of all of the model’s vehicles up to now – as little as 19.4 tonnes of CO2e (carbon dioxide equal) at launch. What does that truly imply and the way was Polestar in a position to obtain it?
A automotive’s carbon footprint is calculated primarily based on its vitality consumption – take into account that the vitality supply can also be vital – and CO2 emissions. These embody emissions attributable to the extraction of gasoline, minerals, and different uncooked components, the manufacturing of the varied components, the meeting of the automotive, the logistics chain it is determined by whereas in use, its recycling, and its finish of life. Principally, every part from the second a automobile’s manufacturing begins till it may well not be used.
Nonetheless, within the case of the Polestar 4, the figures correspond to the automobile’s cradle-to-gate carbon footprint which incorporates materials acquisition by way of the manufacturing of the product; the evaluation excludes the use and end-of-life levels, in order that’s price holding in thoughts.
As you may think about, manufacturing a automobile with a low carbon footprint is not any straightforward process and takes loads of planning, which is strictly the case with the Polestar 4.

“To help our internet zero purpose, we set carbon budgets for all our vehicles,” stated Fredrika Klarén, Head of Sustainability at Polestar. “All through the product growth of Polestar 4, its carbon finances has influenced every part from materials selections to manufacturing unit vitality sources. Sharing the LCA allows us to point out that we are able to attempt for internet zero – one tonne of CO2e at a time.”
So how did Polestar attain a carbon footprint of 19.4 tonnes of CO2e for the Polestar 4 at launch?
For starters, the electrical crossover coupe is constructed at Geely Holdings’ SEA manufacturing unit in Hangzhou Bay, China, combining inexperienced electrical energy that mixes hydropower electrical energy with photovoltaic electrical energy from the roof of the plant. The local weather influence is diminished additional because of the upper use of low-carbon aluminum from smelters utilizing hydropower electrical energy.
As well as, Polestar added information concerning the share of recycled aluminum to the evaluation for the primary time. The carmaker claims aluminum makes up 23-24 % of the carbon footprint, whereas metal and iron signify 20 %.
Unsurprisingly, battery modules account for the best share of the carbon footprint of supplies manufacturing and refining at 36-40 %.
The Polestar 4 variant with the bottom carbon footprint of 19.4 tonnes of CO2e is the Normal vary Single motor, adopted by the Lengthy vary Single motor model with 19.9 tonnes CO2e. The Polestar 4 Lengthy vary Twin motor has the best carbon footprint of the lineup at 21.4 tonnes CO2e. We requested Polestar the place these variations come from and we’ll replace the story after we hear again.
Polestar publishes full particulars of the carbon footprint of all its fashions. The EV maker says it believes the automotive business needs to be a driving pressure within the shift to sustainable mobility, and that transparency is essential for that to occur.
The Swedish model has revealed Life Cycle Assessments since 2020. The LCAs contemplate a spread of things in a automotive’s life cycle, from provide to fabricate and recycling, and allow shoppers to make fast and knowledgeable selections when shopping for a automotive.
Manufacturing of the Polestar 4 is scheduled to start in China this month.
