France is set to ban the sale of any car that uses petrol or diesel fuel by 2040, in what the ecology minister called a "revolution".
Nicolas Hulot announced the planned ban on fossil fuel vehicles as part of a renewed commitment to the Paris climate deal.
He said France planned to become carbon neutral by 2050.
Hybrid cars make up about 3.5% of the French market, with pure electric vehicles accounting for just 1.2%.
It is not yet clear what will happen to existing fossil fuel vehicles still in use in 2040.

China, the world's biggest car market, plans to ban the production and sale of diesel and petrol cars and vans.
The country's vice minister of industry said it had started "relevant research" but that it had not yet decided when the ban would come into force. "Those measures will certainly bring profound changes for our car industry's development," Xin Guobin told Xinhua, China's official news agency China made 28 million cars last year, almost a third of the global total.
Both the UK and France have already announced plans to ban new diesel and petrol vehicles by 2040, as part of efforts to reduce pollution and carbon emissions.
Chinese-owned carmaker Volvo said in July that all its new car models would have an electric motor from 2019.
For anyone who enjoys Things I Won't Work With, this is similar craziness in a longer form. I laughed outrageously over numerous incidences.
Dr. Clark retired from rocket research in 1970 and his long-suffering wife was an impetus for him publishing an account of his experience and expertise in 1972. The stated purpose of Ignition - An Informal History of Liquid Rocket Propellants was for people to avoid repeating mistakes. Indeed, if the contents were more widely understood, particularly the three references to O-rings and numerous references to temperature, the Challenger disaster could have been avoided. The chapter on energy density should also be read more widely because, in 1970, LiH was used to start rockets rather than make batteries which, predictably, catch fire. Likewise, if the USAF had heeded Dr. Clark's advice against the disclosure of a particular technique, SS-1 "Scud" missiles may have been less effective against US personnel.
The book provides a brief and functional history of rocket chemistry before it expands massively into Dr. Clark's first-hand knowledge. No attempt is made to explain rocket hardware which can be obtained from numerous other sources. Dr. Clark's personal technical contributions conclude the longest chapter and this concludes within the first half of the book. The remainder of the book is a number of advanced topics which progress after the industry checkpointed with the success combination of RFNA and UDMH.
Dr. Clark's remaining experience is mostly in an adminstrative capacity of running a chemistry laboratory or the practicalities of industrial test standardization. His speciality was the two types of explosive test. He generally avoided compounds which exceeded a cellulose card-gap test from 30 to 35. Compounds which exceeded this or other limits often led to hurried telephone calls to other labs. Unfortunately, this was too late for one chemist who was blinded in one eye and lost four fingers in an avoidable incident. Numerous people were killed or hospitalized. Although researchers rapidly shied away from the most dangerous compounds, this often came too late for one or two people:
RFNA attacks skin and flesh with the avidity of a school of piranhas. (One drop of it on my arm gave me a scar which I still bear more than fifteen years later.) And when it is poured, it gives off dense clouds of NO2, which is a remarkably toxic gas. A man gets a good breath of it, and coughs a few minutes, and then insists that he's all right. And the next day, walking about, he's just as likely as not to drop dead.
