Getting enough pure battery-electric cars on the road to achieve climate change targets by 2030 is ”like climbing Everest on a bad day” according to the latest RAC Foundation report.
The Climate Change Committee’s Balanced Net Zero Pathway plots a course to net zero that requires a 40% drop in annual CO2 emissions from cars (a fall from about 57 million tonnes in 2021 to around 34 million tonnes by 2030).
The RAC Foundation says there are several ways this could be achieved, but if the driving patterns of tens of millions of car owners are to go unchanged, then three other key factors will determine whether the required cuts in carbon emissions are likely to be met:
- The take up of plug-in battery-electric cars,
- The proportion of car-driven miles accounted for by these battery-electric vehicles, and,
- The rate of departure of petrol and diesel cars from the UK’s vehicle fleet.
The modelling reveals that, if the total number of car-driven miles stays steady or continues to grow, then battery electric cars would potentially have to account for some 35% of the total car fleet in 2030 (around 13.5 million electric cars compared to a projected 38.6 million cars in total), and these would have to account for at least 37% of all car miles driven.
The latest government data shows there are currently 33.2 million cars licensed in the UK of which 548,000 (less than 2%) are pure battery electric.
In 2022, according to the SMMT, 1.6 million new cars were sold in the UK, 267,000 (17%) of them pure battery electric.
However, the average age of cars on the road is rising. In 1994 it stood at six years and two months. By the end of 2021 the average age was eight years and four months.
Steve Gooding, director of the RAC Foundation, said: “From the point of view of the planet the next car people buy is critical.
“For those thinking of going electric but wavering, perhaps put off by the up-front price, there is a case for pausing to see how things play out in the next year or two, rather than falling back to petrol.
“People sticking with petrol or diesel should go for the greenest, cleanest model they can, remembering that every fossil fuelled car bought today is going to be with us for at least a decade and probably far longer.”
“Based on current trends getting the car fleet up to 35% pure battery-electric by 2030 without reducing driven miles looks like a monumentally steep challenge, like climbing Everest on a bad day.”
He said that bearing in mind annual mileage per car was already falling way before Covid, maybe planning for a reduction in total car mileage wouldn’t be as contentious as some fear, particularly if accompanied by complementary policies, such as support for public transport.
“Despite the challenge of austerity, if the Chancellor was canny he could use VED to push car buyers more firmly towards electric options, encourage petrol-car purchasers to choose models offering the best-in-class fuel-efficiency and in doing so actually raise some cash he could then use to cut the costs of electric motoring.”
