Carmakers: How Clean Are Electric Vehicles Compared to Traditional Cars?

Carmakers are investing billions of dollars in the development of new battery electric vehicles (BEVs) in hopes of putting over 30 million of them on European roads by 2030. With their promise of reduced emissions and a greener future, these electric cars are receiving significant attention. However, it is important to recognize that while electric vehicles themselves may produce no tailpipe emissions, their manufacturing process is not entirely carbon-free. In this article, we will explore the environmental impact of BEVs and compare them to traditional internal combustion engine (ICE) cars.

The life cycle emissions of a product include those created during its production, use, and disposal. For electric cars, this encompasses everything from raw material extraction and battery power sourcing to vehicle recycling and reuse. The production phase of battery electric cars, particularly the extraction, refinement, transportation, and manufacture of lithium-ion batteries, contribute significantly to carbon emissions. In comparison, the manufacturing process for ICE cars may have a lower carbon footprint, but it still leaves a notable impact.

To address the carbon emissions issue, several carmakers have made ambitious commitments. Volkswagen and Toyota, for instance, have set goals to become carbon neutral by 2050, while Hyundai Motor Group and Mercedes-Benz plan to achieve carbon neutrality by 2040 and 2039, respectively. Swedish company Polestar aims even higher, striving to develop a net-zero car by 2030, eliminating all carbon emissions throughout the production cycle. These efforts highlight the increasing importance placed on sustainability within the automotive industry.

When comparing BEVs to ICE cars in terms of carbon emissions, research by Transport & Environment (T&E), a European organization promoting sustainability, reveals some promising findings. On average, an electric car in the European Union is nearly three times better in terms of carbon emissions than an equivalent petrol or diesel car. Furthermore, this gap continues to widen. As the electricity grid becomes greener and relies more on renewables, the benefits of BEVs will only increase. Even in countries like Poland, where electricity generation relies heavily on fossil fuels and batteries may be produced in China, electric cars emit 37% less CO2 than petrol-driven vehicles.

Additionally, an electric car with a battery produced and driven in Sweden can achieve an impressive 83% reduction in CO2 emissions. Looking ahead, T&E predicts that by 2030, electric cars purchased in the European Union will reduce CO2 emissions four-fold as the region’s electricity grid becomes greener and more reliant on renewable energy sources.

While the environmental impact of electric cars is a critical consideration, another crucial aspect is the battery technology they utilize. The price of BEVs is influenced by the raw materials involved in battery production, making them more expensive than their ICE counterparts. However, as battery technology improves, alternatives to the standard lithium-ion chemistry are emerging. Chinese battery giant CATL, for example, is developing a new sodium-ion battery that does not rely on rare minerals like cobalt.

Furthermore, car manufacturers like BYD are recognizing the importance of reducing the use of rare minerals in battery technology. BYD’s Blade Battery unit is produced without cobalt, demonstrating a commitment to sustainability. However, more can be done to reduce the environmental impact of mining activities. Reinvesting mining profits into local communities to support education and training could provide opportunities that are often inaccessible to individuals in developing countries.

A critical step in reducing life cycle emissions from electric cars is the recycling or reuse of batteries. The European Commission has proposed sustainable battery legislation, the first of its kind globally, which aims not only to promote ethical mining practices but also to increase the effective recycling of raw materials. The Council of the EU has already adopted regulations regarding end-of-life requirements for batteries, including targets for collection, material recovery, and extended producer responsibility. These measures will contribute significantly to fostering a circular economy.

Instead of being discarded, batteries that are unsuitable for reuse in cars can serve a “second life” purpose, such as electricity storage on the grid. This innovative approach helps lower the overall carbon footprint associated with battery production. Additionally, investment in battery recycling is essential to make the most of existing resources. However, the sustainability and environmental impact of the recycling process itself remain topics of debate, as it can have a high carbon footprint.

Considering all the evidence, it becomes clear that electric vehicles, over their driving lifetimes, create fewer carbon emissions than traditional ICE cars, making them more environmentally friendly. Ongoing advancements in battery technology and manufacturing techniques will lead to extended battery lifetimes and, consequently, longer lifespans for electric vehicles. Although significant challenges remain throughout the entire life cycle of BEVs, it is crucial to remember that the impact of oil extraction for fuel, which ICE cars rely on, is much greater.

In conclusion, while the manufacture of electric vehicles does contribute to carbon emissions, their overall environmental impact is less significant compared to traditional internal combustion engine cars. As carmakers continue to invest in research and development, the future of electric vehicles looks promising. With sustainable manufacturing practices, increased use of renewable energy sources, and effective battery recycling programs, the transition to electric mobility will play a vital role in creating a greener and more sustainable world.
