The carbon footprint of the Polestar 3 is 24.7 tons of greenhouse gases (CO2e) during its production phase, which is lower than that of the Polestar 2 when it was launched in 2020. This reduction is largely due to efforts in minimizing emissions from aluminum and battery production, where renewable energy is used extensively. For instance, 81% of the aluminum production and all of the lithium-ion battery cell module production use 100% renewable electricity, resulting in a significant decrease in emissions.
The majority of the greenhouse gas emissions come from the extraction and processing of materials like aluminum, steel, and batteries, which together account for about 68% of the total emissions. Specifically, aluminum contributes 24%, steel accounts for 17%, and battery module production also contributes 24% to the overall carbon footprint. By focusing on sustainable practices and renewable energy, Polestar aims to further reduce its environmental impact in the future.
