hoy no circula, ciudad de méxico – estado de méxico (2017-2022)
“Hoy No Circula” is an environmental program started in 1989 to improve the air quality of Mexico City and the the State of Mexico, which surrounds Mexico City on three different sides.
The program consists of prohibiting the circulation of 20% of vehicles from Monday to Friday based on the last digit of their license plates. In 1992, the United Nations declared Mexico City the most polluted city on Earth. Since then, Mexico City’s air quality has improved but still faces significant challenges from pollution.
