When it comes to city pollution, Paris mayor Anne Hidalgo is clearly ready for battle. Speaking to the French press Sunday, Paris’ first female mayor announced what could be the most drastic anti-pollution measures any major world city has implemented yet: By 2020, no diesel fuel at all will be burnt within Paris. Regular cars will be banned outright from its more polluted roads, which will be open solely to electric and hybrid vehicles. Meanwhile, the city’s most central districts (the first four arrondissements) will be barred to all but residents’ vehicles, deliveries, and emergency services, transforming Paris’ Right Bank core into a semi-pedestrian zone. As a counterbalance, the number of cycle lanes will be doubled by 2020, while the city will fund an extended electric bikeshare scheme to encourage more people to get on two wheels. “I want us to be exemplary” Mayor Hidalgo has declared. She seems to be putting money where her mouth is.
