As well as detailing the energy and CO2 produced in the manufacture of the 2 compared with a petrol-engined Volvo XC40, Polestar said it is planning to reveal more about the wider environmental impact of building electric vehicles.
Company boss Thomas Ingenlath said: “Car manufacturers have not been clear in the past with consumers on the environmental impact of their products. That’s not good enough. We need to be honest, even if it makes for uncomfortable reading.”
The firm’s analysis showed the 2 has a lower environmental impact over its lifetime than a petrol-engined XC40, but it also stated that “going green isn’t quite as simple as just buying an electric car”.
It added: “It’s tempting to assume that we can achieve a sustainable and emission-free future by simply getting everyone to drive electric cars. But the truth is a lot more complicated.”
Polestar says manufacturing a 2 creates 24 tonnes of CO2e (CO2 equivalents), compared with just 14 tonnes of CO2e to make a petrol-engined XC40. This extra CO2 is largely attributable to the production of the battery pack needed for the EV. Depending on the source of power used to charge the Polestar during its lifetime, the EV will eventually offset the XC40’s lower manufacturing CO2 footprint, becoming the ‘greener’ of the two cars.
There has been considerable controversy in the automotive industry about the ‘embedded energy’ in battery packs, with claims that manufacturing large batteries particularly results in a ‘carbon footprint’ that makes nonsense of claims that EVs are the energy-efficient future of motoring.
