On 18th September 2022, Brussels instituted a no-cars Sunday as part of European Mobility Week. From 09:30 am to 19:00 pm, cars were prohibited from much of the city to prioritize walking, cycling, and public transport.
Outside of cultural and holistic benefits, Bruxelles Environment, the city’s environment agency, measured a 90% reduction in nitrogen monoxide and nitrogen dioxide, both of which are toxic substances emitted by combustion engines. Additionally, the city saw significant drops in noise levels, again seeing an approximate 90% decrease in typically congested areas; this further demonstrates what modern urban planners have been suggesting in recent years, “cities are not noisy, cars are noisy“
“Authorities point out that yearly emissions have been going down since 2019, by about 10% per year. However, there is still a long way to go, since according to the European Environment Agency, in 2018, Belgium registered around 8,900 deaths caused by air pollution.”
