How Eco-Friendly Are Electric Vehicles in 2023?
Many people are choosing electric vehicles as a more environmentally friendly option. However, in some ways, e-cars are just as bad for the environment as traditional cars. So, what’s the deal?
E-cars do not emit greenhouse gases that are harmful to the environment or nitrogen oxide harmful to one’s health. They’re quiet and simple to use. Electric vehicles appear to have numerous advantages over gasoline or diesel-powered vehicles.
Vehicles contribute to nearly 24% of the world’s emissions
Indeed, with revelations about the auto industry cheating on emissions tests, many consumers are feeling duped – and looking for ways to stay away from any deception. Switching to an electric vehicle is one way to accomplish this.
However, there are several pitfalls associated with the use of electric vehicles:
Getting emissions off the roads and into power plants
The overall carbon footprint of a battery-operated vehicle is comparable to traditional-fuel vehicles, regardless of size; the Institute for Energy and Environmental Research (IFEU) in Heidelberg came to this conclusion in a 2011 study. And, even a recent UNCTAD report expressed environmental concerns over the raw material required for rechargeable batteries.
While less CO2 is emitted by cars while driving on the streets, power plants still emit CO2 to charge electric vehicles.
Production of energy-intensive batteries
The production of electric vehicles is currently the most severe environmental issue. According to a study conducted by the Fraunhofer Institute for Building Physics, it takes more than twice as much energy to manufacture an electric car as it does a conventional one.
The battery is the primary reason for this. According to the institute, the calculation for each kilowatt-hour of the capacity of the batteries comes up to 125 kilograms (276 pounds) of CO2 emissions. This equates to nearly 3 tonnes of CO2 for a 22-kilowatt-hour battery for a BMW i3.

Batteries must also be made from minerals such as copper and cobalt and rare earth such as neodymium.
Furthermore, many automakers use aluminium to construct the bodies of electric vehicles, and processing bauxite ore into lightweight metal requires a tremendous amount of energy.
Greenwashing with electricity?
Because of their indirect emissions, electric vehicles have sparked debate about whether they can be labelled as “zero-emission vehicles.” It’s a question with far-reaching implications.
By producing “zero-emission” vehicles, automakers can continue to sell gas-guzzling vehicles such as SUVs that exceed these limits.
However, e-cars powered by renewable energy production up to six times fewer carbon emissions than a gasoline car over its lifetime.
This means that, for the transition to e-mobility to be as effective as possible, countries will need to transition their energy generation simultaneously.
Disposal of batteries
Concerns have also been raised about what happens to the complex batteries, which also contain toxic chemicals, at the end of the life of an electric vehicle. Will this result in a new environmental crisis?
Scientists at several universities are working on ways to recycle and reuse electric vehicle batteries, for example, in industrial processes. The longer the battery can be used after the vehicle’s life, the lower its environmental impact over its lifetime.
There is also ongoing research to improve the efficiency of the batteries while they are in the vehicle. Engineers are also investigating how electric vehicles can be used as storage devices in the overall energy grid.
When the sun isn’t shining, and the wind isn’t blowing, a car plugged in overnight could feedback into the grid.
While there is general agreement that electric cars are not truly “zero-emission” vehicles, they are still better for the environment and the climate than conventional vehicles.
The key in the coming years will be determining how to make these new vehicles even more environmentally friendly.
EVs are essential to more sustainable transportation because they are a cleaner alternative.
While they have their cons, EVs can help the environment in several ways.
1. EVs have zero tailpipe emissions.
Because they do not emit exhaust, fully electric vehicles do not require a tailpipe. Traditional engines burn gasoline or diesel, producing energy at the expense of harmful carbon emissions.
EV batteries, on the other hand, are entirely emission-free. The lithium-ion battery is the most common type of battery used in EVs. These batteries can be discharged and recharged repeatedly without polluting the environment.
2. EVs and their carbon footprint
EVs emit less pollution than ICE vehicles. Many electric charging stations charge EVs with renewable energy. However, some are still powered by coal-fired power plants and other environmentally hazardous energy sources. Charging EVs can have a greater carbon footprint in countries that primarily use coal, oil, or natural gas for power.
However, even when EVs are powered by coal, they result in lower overall emissions. Electric cars have resulted in a 20% reduction in greenhouse gas emissions in coal-dependent countries such as China. Clean energy sources enabled EVs to be even greener in countries that rely less on fossil fuels.
3. EV battery production can be environmentally friendly
Although EVs do not contribute significantly to roadside air pollution, the production of EV batteries can be hazardous if done irresponsibly. Almost all EV emissions are well-to-wheel emissions produced during the battery manufacturing process.
Because EVs are still a newer technology, industry standards for the energy sources used to make batteries are inconsistent, resulting in higher carbon footprints. However, this is beginning to change.
Today’s EV batteries have a carbon footprint two to three times lower than it was two years ago
EV manufacturers are developing guidelines for their battery suppliers. For example, they require suppliers to use only renewable energy sources during production, such as solar and wind.
These sources can provide the large amount of energy required to manufacture EV batteries while emitting no harmful emissions. Tesla, for example, intends to manufacture its batteries using only renewable energy.
4. ICE vehicles emit pollution on a continuous basis
EVs do not contribute to air pollution after they are manufactured, with the exception of the limited use of coal-fueled charging stations. The majority of emissions are generated during the battery manufacturing process. This means that an EV’s total emissions can be measured before it even starts up for the first time.
Internal-combustion-engine (ICE) vehicles, on the other hand, emit CO2 whenever their engines are turned on. A gasoline-powered passenger vehicle emits 5 to 6 metric tonnes of CO2 per year on average. According to a study conducted by the Union of Concerned Scientists, ICE emissions outperform EV well-to-wheel emissions in as little as 6-18 months of operation.
With millions of ICE vehicles on the road worldwide, emissions continue to be massive. Alternatively, an electric vehicle powered by renewable energy will always have a zero carbon footprint.
5. EV manufacturers use environmentally friendly materials
One of the most difficult challenges for EV manufacturers is creating a functional, lightweight vehicle. Lighter EVs have a longer range and a lower carbon footprint, but traditional materials make this difficult. On the other hand, recycled and organic materials are now at par with traditional materials. They are lightweight, eco-friendly, strong, and long-lasting.
Many conventional manufacturers use recycled materials for small components but do not use them for vehicle structures at the moment. Eco-friendly materials are being used and improved by EV manufacturers to build lighter, more efficient vehicles.
Using recycled and organic materials not only saves weight but they are also better for the environment.
Using new materials such as metals and plastics is unsustainable and pollutes the environment. Natural or recycled materials reduce environmental impact both during and after the EV manufacturing process.
Electric vehicles are far less polluting than their combustion engine counterparts as they currently stand. As the technology becomes more widely used, it is expected to become more efficient and sustainable. Economies of scale will help EV manufacturing by providing better infrastructure, more efficient manufacturing techniques, recycling options, and reducing the need for new material mining.
Electric vehicles are not a panacea, but when combined with increased renewable energy deployment and grid decarbonization, they provide a path to significantly reduce greenhouse gas emissions.
