Authorities in Paris, France are forcing drivers to slow down as they set a 30km/h speed limit on roads. The measure aims to reduce pollution and improve traffic safety. Some argue that the move could aggravate the city’s rush-hour traffic jams, which could increase greenhouse gas emissions. The rule change took effect on August 30, 2021. Under the new law, officials will also be removing 60,000 parking spaces on public roads to make them “more accessible to everyone.” In addition, some sidewalks will be widened and bike lanes will be installed.

Based on the results of a poll conducted by the Parisian City Hall, only 59% of the city residents were in favor of the new limit. A delivery driver described the rule as “crazy” and likened it to riding on “electric scooters”. Parisian leader David Belliard, who is in charge of transport, hopes that the limit would encourage more people to walk and use bikes. Moreover, officials said that the change is expected to reduce total road accidents by an estimated 25% and fatal accidents by 40%, attributing to a World Health Organization research. The rule change is also intended to reduce noise pollution, which had negative physical and psychological effects on people, including stress and depression.
