Objective Proficiency p 110. France set to ban sale of petrol and diesel vehicles by 2040. Extra Reading

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.

Mr Hulot, a veteran environmental campaigner, was appointed by new French President Emmanuel Macron. Mr Macron has openly criticised US environmental policy, urging Donald Trump to "make our planet great again".
President Trump's decision to withdraw from the Paris climate change agreement in June was explicitly named as a factor in France's new vehicle plan.
"France has decided to become carbon neutral by 2050 following the US decision," Mr Hulot said, adding that the government would have to make investments to meet that target.
Poorer households would receive financial assistance to replace older, more polluting vehicles with cleaner ones, he said.
Earlier this week, car manufacturer Volvo said all of its new car models would be at least partly electric from 2019, an announcement referenced by Mr Hulot.
He said he believes French car manufacturers - including brands such as Peugeot-Citroen and Renault - would meet the challenge, although he acknowledged it would be difficult. Renault's "Zoe" electric vehicle range is one of the most popular in Europe.
However, traditional fossil fuel vehicles account for about 95% of the European market.
Other targets set in the French environmental plan include ending coal power plants by 2022, reducing nuclear power to 50% of total output by 2025, and ending the issuance of new oil and gas exploration licences.
Several French cities struggle with high levels of air pollution, including Paris, which endured several days of peak pollution in March.
The capital has implemented a range of measures to cut down on cars, but air pollution is also a problem in picturesque mountain regions.
Last month, a woman took the French state to court over what she said was a failure to protect her health from the effects of air pollution in Paris.
Norway, which is the leader in the use of electric cars in Europe, wants to move to electric-only vehicles by 2025, as does the Netherlands. Both Germany and India have proposed similar measures with a target of 2030.
