Polestar to track CO2 equivalents in supply chain

Polestar has entered into a strategic partnership with blockchain provider Circulor. One element of the partnership is tracking CO2 equivalents through the supply chain, which will help meet Polestar's goal of building a carbon-neutral car by 2030.

Circulor helps companies set up more sustainable supply chains and works with blockchain technology to track materials, which also helps ensure that the materials used to make batteries come from the exact mines or recycling facilities selected for them, Polestar said.

Blockchain technology is already being used in Polestar 2 to ensure the traceability of cobalt in its batteries. Another part of the partnership is the tracking of CO2 equivalents , called CO2e, which will allow Polestar to show its customers the emissions generated during the production process per plant, as well as those taken from suppliers through the supply chain.

A "digital twin" for the raw material is created for the process and the material is then tracked through the supply chain - so that the path can be recorded "like a red thread" even across different work steps. Generic emissions data from databases are also linked for CO2 tracking.
