Paris is a living organism that breathes through its pulmonary alveoli of green spaces. Due to the high concentration of human activities, the respiratory system of the city is put under heavy stress to remove air pollutants. Because most of the city’s public health initiatives focus on reducing outdoor air pollution, the (underground) metro’s poor air quality remains unadressed. (continue reading below)
Our project aims to improve the health and well-being of the 4 million daily users of the Parisian metro and, potentially, of the 150 million daily metro passengers in the world.
We propose transforming the Paris metro network into the first urban lymphatic network, capable of filtering pollutants from the air via phytoremediation. Each station, a true underground lymph node, would be progressively equipped with both air pollutant sensors that measure air quality in real time and green walls tailored to local pollutant types and levels.
Furthermore, the presence of vegetation in the Parisian metro would boost user well-being by reducing stress and fostering a healthy emotional and mental balance.
Thus, by addressing both the physical and mental health of Parisians, VégéStation provides a sustainable, Smart City approach to the often-overlooked, but serious issue of metro air quality.
