In recent years we’ve seen a real shift towards electric cars as more of us try to do our bit to fight climate change. Governments are encouraging us to switch to electric vehicles and the UK will be banning the sale of new petrol and diesel cars from 2030.

But are electric cars better for the environment? In this blog post, we’ll be looking into whether that’s actually true and what the environmental impact of electric cars is.

Are electric cars better for the environment?

Fighting climate change has been at the forefront of the public’s minds for a few years now and is becoming increasingly important as pressures on our planet’s resources grow. Recently, there has been a real shift towards electric cars as an environmentally clean option, especially as the UK will be banning the sale of new petrol and diesel cars from 2030, which begs the question, are electric cars really better for the environment?

Well, electric cars emit fewer greenhouse gases and air pollutants than petrol or diesel cars – even when their production and electricity generation to keep them running is considered. Just one electric car on the roads can save an average of 1.5 million grams of CO2 in a year. This is because electric cars have no tailpipe producing carbon dioxide emissions while the car is running.

Electric cars also help to improve the air quality in towns and cities, providing cleaner streets for pedestrians and cyclists. So, the sustainability of an electric car is much higher than a conventional vehicle.

The UK’s Net-Zero Target and EVs

Transport is currently responsible for 25% of total UK greenhouse gas emissions. With this being said, it is no shock that the UK government and local councils are eager to increase the number of electric vehicles on the roads. In a bid to do this, the UK government aims to ban the sales of petrol and diesel vehicles by 2040 and by 2050, they are aiming to reduce carbon emissions to zero.

Furthermore, electric vehicles also contribute to reducing noise pollution as they are much quieter than conventional vehicles, providing a more peaceful environment for everyone.

Environmental impact of manufacturing an electric car

Although driving an electric vehicle doesn’t emit any CO2 - manufacturing one does. In the electric vehicle manufacturing process, there are more emissions produced in comparison to the manufacturing of conventional vehicles because of their lithium-ion batteries. The production of these batteries is CO2 intensive as they are made up of rare earth elements, and the extraction of these elements is energy intensive.

As time goes on and technology advances, this process will become more efficient and sustainable. Reusing and recycling batteries is also an option, lowering the emission rate further as batteries are used in new technology like electricity storage.

Even now, with the higher manufacturing emissions, electric vehicles are seen as a greener solution due to the reduction in emissions throughout the car’s lifespan.

Environmental impact of charging an electric car

Even with the electricity generation to charge an electric vehicle, the carbon emissions are significantly lower than that of a conventional vehicle. The environmental impact of charging an electric vehicle is also dependent on the source of electricity. For example, when the electricity comes from renewable sources such as wind, the electricity generated emissions are significantly improved.

Electric vehicle owners should be mindful of their car charging process and battery disposal to help minimise the environmental impact.

Environmental impact of producing EV batteries

Producing electric vehicle batteries has an environmental impact mainly due to the extraction and processing of raw materials required to produce the batteries.

Currently, most car batteries are produced in China, South Korea, and Japan, where the use of carbon in electricity production is quite high. However, as we see more electric vehicles hit the roads, more battery production facilities are beginning to open in the UK and Europe.

Efforts are being made to reduce the environmental impact of electric vehicle battery production using renewable energy sources, recycling materials, and more efficient production processes.

Hybrid cars and the environment

Hybrid cars combine an electric battery with a conventional fuel engine, so if you were to run your hybrid vehicle on mostly electric power then it would be a greener option. However, if you were to power your car mostly / fully on fossil fuels then this would be producing the same amount of emissions as a conventional vehicle. The emissions produced by a hybrid vehicle depend on how you power it.

FAQs

Are electric cars better for the environment in the UK?

Yes, generally speaking, electric vehicles are more environmentally friendly over time than a car that runs on diesel or petrol. But you may be wondering, why are electric cars better for the environment? The simple answer is that electric cars emit fewer greenhouse gases and air pollutants, making the overall sustainability of an electric car much higher than that of a conventional vehicle.

How bad is the production of electric cars for the environment?

The CO2 emissions created from electric vehicle production are higher than those of a conventional vehicle, mainly due to battery production. However, over the lifespan of an electric vehicle, they work out to be a greener option as they produce fewer emissions over time.

Are EV charging stations good for the environment?

EV charging stations are beneficial to the environment as they reduce emissions that contribute to environmental change, improve public health, and contribute to reducing ecological damage.

Is mining lithium bad for the environment?

Although there are downsides to lithium, it makes renewable energy possible. Lithium mining harms the soil and causes air contamination. Other common side effects on the environment are water and biodiversity loss and toxic waste. However, lithium is an essential component in rechargeable batteries.
