Polestar has published lifecycle assessments, or LCAs, for all models since 2020 to identify emissions from materials and manufacturing and reduce the climate impact of vehicle production.
For the Polestar 5, total greenhouse-gas emissions before delivery are 23.8 tons, covering the process from raw-material extraction through production and delivery to the customer.
The company said it is working to cut emissions by using more environmentally friendly materials. Aluminum is considered one of the most carbon-intensive materials in vehicle manufacturing.
Polestar said it overhauled how aluminum is sourced for the Polestar 5: 13% of the aluminum is recycled, and 83% is produced at smelters powered by renewable energy. The company said that reduces greenhouse-gas emissions by more than 14 tons per vehicle compared with conventional methods.
Renewable energy also plays a key role in production, Polestar said. The Polestar 5 uses renewable power not only at its manufacturing facilities but also at sites producing battery cell modules and key battery materials, cutting emissions from vehicle, parts and battery manufacturing. Polestar also said it used new materials in the interior to reduce environmental impact and applied circular design to the front trunk.
"If you don’t measure it, you can’t reduce it," said Fredrika Klaren, Polestar’s head of sustainability. Disclosing a car’s carbon footprint, she said, "clearly shows where emissions occur" and encourages industry efforts to cut emissions from materials and manufacturing. She added that such transparency is essential to expanding low-carbon materials, renewable energy and circular solutions and reducing the auto industry’s climate impact.
