The "Doble Hoy No Circula" initiative has been an important measure to mitigate air quality within Mexico City's Comprehensive Program Against Atmospheric Pollution (PICCA). This measure was implemented as an urgent response to the growing air quality crisis. It current model began in 2014, aiming to restrict the use of private vehicles on specific days to reduce pollutant emissions and improve public health. In a megacity like Mexico City, where mobility and pollution are interconnected, policies like this affect not only the environment but also the health and well-being of its inhabitants.
