London, United Kingdom | AFP | Technological advances mean fossil fuel in cars could be phased out within decades but switching to electric carries its own environmental and economic concerns as more and more countries announce radical plans.
Britain on Wednesday said it would “end the sale of all conventional petrol and diesel cars” by 2040, following similar proposals by France earlier this month to reduce nitrogen dioxide (NO2) pollution.
China issued plans last year requiring that 12 percent of cars sold be battery-powered or plug-in hybrids by 2020, while India has said it wants to replace all vehicles with electric vehicles by 2030.
Norway hopes to end sales of new petrol and diesel cars by 2025, and other countries such as Sweden and Denmark and Finland have expressed similar ambitions to phase out fossil fuel engines.
“Given the rate of improvement in battery and electric vehicle technology over the last ten years, by 2040 small combustion engines in private cars could well have disappeared without any government intervention,” said Alastair Lewis, professor of atmospheric chemistry at the University of York.
“Nonetheless this is highly symbolic since it signals to both the public and to manufacturers that there is no turning back from electrification,” he added.
Stefan Bratzel, director of the Center of Automotive Management (CAM), said that last year proved to be a “tipping point”, shifting political will into concrete commitments.
He highlighted the emissions scandal, where manufacturers of mainly diesel cars were found to have cheated on environmental tests.
Local and national environmental targets and the progress made by China in developing electric cars are also forces propelling the move away from hydrocarbons.
– A ‘bold bet’ –
But Flavien Neuvy, economist at French automobile anlaysts Observatoire Cetelem, said it would be a “bold bet” to suggest that the roads will be filled with only electric cars by 2040.
“To say that we forbid combustion engines in 2040 assumes that we already know which will be the most efficient technology in 2040,” he told AFP.
“It’s a bold bet because the combustion engine, from an environmental point of view, may become more favourable, as can be seen with cars that can now travel 100km on 2 litres of fuel”.
He also believes that the electric car “will be much more efficient than today”, and that an improvement from the current average range of 250-300km to 400-500km would be “enough” to make them viable.
“But in reality, there are many other fuels, such as gas, hydrogen, and manufacturers are investing heavily in the self-drive car,” he added.
