Petrol and diesel cars waste ‘hundreds of times’ more raw materials than electric vehicles over a lifetime, claims report by green campaigners

Cars with petrol and diesel engines waste hundreds of times more raw materials than an equivalent electric vehicle, according to a new study by a green campaign group.
Over the course of a fossil-fuel car’s lifetime it burns through the equivalent of a stack of oil barrels 25 storeys high, while electric vehicles waste only a football-sized 30kg of metals, the report released by Transport & Environment claims.
However, the campaign group’s calculations are weighed heavily towards plug-in cars running predominantly on electricity generated by renewable sources – and the extensive recycling of minerals and materials from batteries for reuse in new electric vehicles.+5
Fossil-fuel cars waste ‘hundreds of times’ more of the world’s raw materials than electric vehicles, according to a new report published by Transport & Environment. However, the study is weighted heavily in favour of EVs running on clean electricity and batteries being recycled
The campaign group believes the research shows that battery electric vehicles are superior to their internal combustion engine counterparts across raw material demand, energy efficiency and cost, while at the same time reducing emissions.
It says that an average of 17,000 litres of oil is burned to power a fossil fuel car throughout its life.
And once you adjust the calculation of the resource used relative to weight, it estimates that petrol and diesel models are between 300 and 400 times more wasteful than EVs.
The report comes in the wake of announcements by major car makers that they will be ditching petrol and diesel engines before the end of the decade as part of their commitment to going green from 2030.
Ford, Jaguar Land Rover and – most recently – Volvo have all outlined their strategies in the last few weeks to move away from conventional internal combustion engines and shift to electrified powertrains. +5

The shift to electric cars will ultimately see mining of minerals, such as lithium (pictured), accelerated to keep up with demand for batteries
These accelerated plans to sell only electric cars by 2030 will ultimately come at an environmental cost with the increased production of batteries demanding more mining of minerals such as lithium, cobalt and nickel.

The fuel would not require any modifications to a car and be compatible with both current and older vehicles – and it could make existing motors as clean as electric cars, when you take into account the carbon footprint created during production and supply.
The German sports car maker has been working in partnership with Siemens Energy and other international companies since last year to develop and implement a pilot project in Chile designed to yield the ‘world’s first integrated, commercial, industrial-scale plant for making synthetic climate-neutral fuels’.
If operational in 2022, Porsche says it could be producing 55m litres of synthetic fuel by 2024, and as much as ten times that amount by 2026.
However, T&E argued that despite this the waste gap between fossil-fuel cars and electric vehicles will increase.
It says that technological advancements will drive down the amount of lithium required to make an EV battery by half over the next decade.
It adds that the amount of cobalt required will drop by more than three-quarters and nickel by around a fifth.
It also argued that the cost of oil extraction for fuel represents a much greater environmental toll.
‘When it comes to raw materials there is simply no comparison,’ said Lucien Mathieu, a transport analyst at the green campaign group – who is also the author of the new report released this week.
‘Over its lifetime, an average fossil-fuel car burns the equivalent of a stack of oil barrels 25 storeys high.
If you take into account the recycling of battery materials, only around 30kg of metals would be lost – roughly the size of a football.’
Transport & Environment’s report on the eco benefits of electric vehicles came as consumer group Which? released findings from its own research that showed that plug-in hybrid cars – which use a combination of combustion engine, battery and electric motors – aren’t as green as maker claim.
It found that they use up to four times more fuel than official figures suggest and could be costing owners £450 more a year than expected.
Electricity generated by renewable sources and battery recycling key to making EVs greener
T&E estimates that battery electric cars will use 58 per cent less energy than a petrol car over its lifetime and emit 64 per cent less carbon dioxide.
It adds that emissions associated with electric cars are mainly produced in the ‘energy-intensive manufacturing of batteries’, while the vast majority of emissions associated with internal combustion engine cars come from its use.
But while the calculation used takes into account the production of electricity to power EVs it is, however, weighted heavily on battery cars using energy produced by solar panels and wind turbines.
The report says: ‘For the BEV [battery electric vehicle], around 60 per cent of energy is from the electricity produced to recharge the car (including the various losses and efficiencies), then comes the battery production (23 per cent of the total), the vehicle production (excluding the battery, 11 per cent), and finally the lifecycle energy needed to produce the solar panel and wind turbines which produce the electricity (7 per cent).
‘On the other hand, 77 per cent of the lifecycle energy consumption from a petrol car is directly linked to the energy content of the fuel burned in the use phase, to which another 18 per cent accounts for the upstream energy consumption from the fuel extraction, refining, production and transportation.’
In the UK, around 40 per cent of electricity is generated by renewable sources. However, in countries like China, some 80 per cent of its national grid is reliant on coal-generated energy, which somewhat nullifies the eco credentials of cars that emit no emission from tailpipes.+5

T&E’s estimation about wastage is also based on a high percentage of materials in end-of-life batteries being recycled for reuse in new electric vehicles.
