Add new comment to Polestar 5 Carbon Footprint Revealed With Full Lifecycle Data

Polestar has published the full carbon footprint of the Polestar 5, and the big story sits in the data. The company's new life cycle assessment pegs the Polestar 5 carbon footprint at 23.8 tCO2e from cradle to gate, then 38.1 tCO2e over its full life under a global electricity mix. Switch the charging profile to a European grid mix and that drops to 30.1 tCO2e. Charge on wind electricity and the total falls again to 27.1 tCO2e.

That matters because most automakers still talk around emissions. Polestar publishes the stack. Looking at the data, the company lays out where emissions come from, how much each phase adds, and which supplier-side changes drove the biggest cuts before the car even reaches a customer.

Why the Polestar 5 report matters

The Polestar transparency play works because it makes the discussion measurable. Specifically, this report uses ISO 14067 methodology, a 200,000 km lifetime assumption, and a 15-year use phase. It also applies third-party critical review, which gives the numbers more weight than a vague sustainability slide or a one-line factory claim.

From an expert perspective, that level of disclosure changes the conversation in two ways:

• It shifts focus from tailpipe-free marketing to full vehicle emissions
• It shows where engineering, sourcing, and supplier energy choices actually move the number
• It gives buyers, investors, and rivals a cleaner basis for comparison

Polestar 5 technical profile behind the footprint

This is not a stripped-down eco special. The assessed Polestar 5 packs serious hardware, and that hardware carries a carbon cost that Polestar had to manage upstream.

Consequently, the car starts from a demanding brief. A large 112 kWh NMC battery, dual-motor all-wheel drive layout, and 2,444 kg study weight do not make low embedded emissions easy. That makes the 23.8 tCO2e cradle-to-gate result more interesting, because Polestar had to squeeze emissions out of materials and suppliers rather than rely on a small battery or a low-performance setup.

Where the

 emissions come from

The biggest chunk comes from material production and refining. That alone accounts for 14.4 tCO2e, or about 60 percent of the cradle-to-gate total. Battery modules add 6.9 tCO2e, while manufacturing and logistics together contribute 2.5 tCO2e.

Here is the key split:

In addition, Polestar says assembly-plant emissions account for less than 1 percent of the total because the plant uses renewable electricity. That point sounds good in a headline, but the deeper lesson sits elsewhere: factory electricity helps, yet materials and battery supply chains still dominate the score. That is where the real fight lives.

Definitions

• Cradle-to-gate: emissions from raw material extraction through production and delivery to handover
• Cradle-to-grave: cradle-to-gate plus use phase, maintenance, and end-of-life
• tCO2e: tonnes of carbon dioxide equivalent, a standard unit that bundles greenhouse gases into one climate-impact figure
