Myth-Busting: Are Electric Vehicles Truly Better for the Environment?

Are electric vehicles truly better for the environment? Discover the facts about their production, carbon footprints, and long-term benefits compared to traditional cars.

Electric vehicles (EVs) are often hailed as a solution to reducing CO₂ emissions, thanks to their lack of tailpipes and the associated pollutants.

However, questions about their overall carbon footprint, especially during production, frequently arise. So, does the argument that EVs are less environmentally friendly than internal combustion engine (ICE) cars hold up? Let’s look at the facts.

Zero Emissions, but Not Zero Carbon
While EVs don’t emit CO₂ during operation, their production involves a “carbon debt.” The manufacturing of batteries, steel, aluminum, and electronics requires significant energy.

If this energy isn’t sourced from renewables, it contributes to the vehicle’s overall carbon footprint. This carbon debt is comparable to the environmental impact of producing everyday gadgets like smartphones and laptops.

Polestar’s Transparency and Progress
Polestar stands out by publishing detailed Life Cycle Assessment (LCA) reports for its vehicles, showcasing their cradle-to-grave carbon footprints. For example, in 2020, the Polestar 2 demonstrated a lower overall carbon footprint than its ICE counterpart, the Volvo XC40. Depending on the energy source for charging, reductions ranged from 14% with the global electricity mix to 57% when charged using wind power.

Continual improvements have further reduced carbon debt. The Polestar 2 Long range Dual motor model, for instance, saw its carbon footprint decrease from 26.1 tonnes of CO₂e in 2021 to 23.1 tonnes in recent models—a 10% improvement.

On the Road: The EV Advantage
An EV’s true environmental benefit shines during its lifetime. The more you drive an EV, especially in regions with renewable energy grids like Sweden, the quicker its initial carbon debt is offset compared to an ICE vehicle. Over time, this makes EVs significantly cleaner in terms of total CO₂ emissions.

Sustainability in Materials and Energy
Polestar actively works to reduce emissions from materials and supply chains. By sourcing aluminum from regions using hydropower and encouraging battery suppliers to utilize renewable electricity, the company continues to cut its vehicles’ carbon footprints. In addition, tools like Octopus Energy’s Intelligent Octopus Go tariff in the UK allow EV drivers to charge during periods of higher renewable energy availability, further reducing climate impact.

The Bigger Picture
As a step toward carbon neutrality and combating climate change, EVs are a powerful tool. While no vehicle can match the environmental impact of walking, EVs offer the best option for minimizing harm when driving is necessary—and they’re only getting greener.
