A discussion of Brussels’ low-emission zone turned attention beyond air quality to who can realistically travel by bicycle. Nitrogen dioxide levels in the city have fallen in recent years. Over a longer period, cycling’s share of trips rose from around 3% in 2010 to 9% in 2024. Those figures describe changes happening alongside one another; on their own, they do not establish that one caused the other.
A cycling group in Molenbeek highlighted a less visible obstacle: the shortage of secure places to leave a bike. For someone considering a bicycle for daily travel, storage can matter as much as the route. The problem is especially acute for larger, more expensive cargo bikes. Covered, lockable spaces are scarce, while the limited bicycle boxes can have long waiting lists.
Low-emission policy and cycling infrastructure therefore need to be considered together. Cleaner air improves the urban environment, while safe routes, accessible parking and opportunities to learn to ride help people make use of it. The Brussels example brings the question back to the front door: a practical journey begins with knowing where the bicycle can be kept.
