EVs – 50% Less Greenhouse-Gas Emissions than Diesels

The Myth

I often hear claims, from EV detractors, that electric cars produce more CO2 than an ICE powered car, because the electricity is produced from polluting sources, and CO2 from the production process of batteries adds to the total.  They skirt round the realities of every ICE powered car having an atmospheric pollution pipe sticking out the back, producing CO2, and rather more, for the entire lifetime of the car. The entire process of oil extraction is highly polluting, and also releases methane into the atmosphere.

The Myth Debunked

A recent report in the Guardian entirely debunks the whole myth.  Researchers calculated that the total life-cycle emissions of an electric car, including its manufacture, battery manufacture, and all of its energy consumption, is significantly less than diesel powered cars, even when they are powered by electricity from coal.   Where the electricity is from renewable sources, the comparison is even more favourable for electric vehicles.  For example –

In Poland, which uses high volumes of coal, electric vehicles produced 25% less emissions than diesels,

but, in Sweden, with Europe’s cleanest grid, electric vehicles produced a remarkable 85% less,

and in the UK, as somewhere in between, EVs still managed 50% less.

Those figures are based on the assumption that drivers would use electricity from all sources, where I know that many drivers seek out 100% renewables, for home charging. All EV drivers on the motorway, using Ecotricity fast-chargers, use 100% renewable electricity.

What the Commissioners of the Study Said

It was reported that Yoann Le Petit, a spokesman for the T&E think tank, which commissioned the study, said -.

“On average, electric vehicles will emit half the CO2 emissions of a diesel car by 2030, including the manufacturing emissions, We’ve been facing a lot of fake news in the past year about electrification, put out by the fuel industry, but, in this study, you can see that, even in Poland, today, it is more beneficial to the climate to drive an electric vehicle than a diesel.”

The Future

The study says that while the supply of critical metals – lithium, cobalt, nickel and graphite – and rare earths would have to be closely monitored, and diversified, that should not constrain the clean transport transition.

As battery technology improves, and more renewables enter the electricity grid, the study found emissions from battery production itself could be cut by 65%.  Batteries might even be replaced by super-capacitors, and efficiency increased even further by the development of room-temperature superconductors.  The future is electric.

About the Author

As a child at school, I had the unrealistic expectation that I would learn about, and understand, absolutely everything, during the course of growing up. Now, at the other end of life, I am fully aware of how much I have not learnt, and do not understand, and yet, I remain interested in everything. My education, starting with an arts degree, and going on to postgraduate studies, in everything from computer science, to hypnotism, reflected my broad interests. For work, I ended up working as a senior officer in local government, and built my career on being a legal eagle for the obscure branch of law, governing the work of my department. I am retired now, and am currently living in North Leicestershire in the United Kingdom, with plenty of time for doing whatever I like. I have always had a keen interest in everything alternative, which includes renewable energy and energy efficiency and, of course, electric vehicles. So, naturally, I have taken ownership of an EV, now that they are affordable and practical forms of transport. Writing is also one of my great pleasures, with various articles and a novel to my name, so writing about EVs is a natural evolution for me.
