On March 6, environmental pollution in Medellín, Colombia, triggered the highest alert levels. For three days, industrial production and driving restrictions (locally known as pico y placa) have been tightened. According to specialists consulted by the local newspaper El Tiempo, meteorological conditions are expected to make the situation “most critical” in two weeks.
In light of situations like this, air quality monitoring and control have taken on greater importance in Colombia. This is especially critical given that one in eight deaths worldwide is caused by air pollution, according to figures from the World Health Organization (WHO). In Colombia, 10,527 deaths and 67.8 million cases of related symptoms and illnesses occurred in 2015, as reported in 2017 by the National Planning Department following a study on the health costs of environmental degradation.

Due to their deep penetration into the respiratory tract, airborne particulate matter under 2.5 microns (PM 2.5) is considered the most hazardous, with potentially severe health impacts. Despite the monitoring protocols in place, the Ministry of Environment warned that no monitoring station in the country currently meets the annual permissible limit of 15 (PM 2.5) established in Resolution 2254 of 2017 as a target for 2030.
So far in 2018, the Institute of Hydrology, Meteorology and Environmental Studies (IDEAM) reported that the most polluted areas in Colombia are Medellín (the Aburrá Valley Metropolitan Area), the localities of Puente Aranda, Carvajal, and Kennedy in Bogotá, the municipality of Ráquira in Boyacá, and the ACOPI industrial zone in the municipality of Yumbo (Valle del Cauca).
Despite ongoing initiatives in several cities—such as Car-Free Day (Día sin carro), incentives to use alternative transit, and the Pico y Placa license-plate-based restrictions—air pollution levels in Colombia continue to rise. This trajectory threatens to trigger severe environmental consequences, which could require even more drastic measures in the future.
The most recent emergency occurred last February, when the Aburrá Valley Metropolitan Area (Medellín) was placed on preventive alert after air quality triggered an orange alert, raising concerns among thousands of local residents. In recent years, air pollution has emerged as the primary environmental concern, demanding collaborative action and targeted focus from environmental authorities, particularly in the most populated and polluting cities.
