Paris is planning to fight smog by permanently banning cars from the city centre and doubling the number of bike lanes by 2020, Grist reports.

“Mayor Anne Hidalgo recently announced an ambitious plan to transform the historic city centre into a ‘semi-pedestrianized’ zone, where walking and biking will be encouraged, and automobile access will be limited to emergency vehicles, residents’ cars, and delivery trucks,” Core writes. “She also hopes to implement an electric-powered bikesharing system, and to eliminate diesel cars by 2020 to curb carbon emissions.”

84% of Paris residents see fighting pollution as a priority, according to a recent poll for the Journal de Dimanche, and 54% support a diesel ban by 2020.
