View of the smog over the city of Santiago on August 3, 2023. Santiago, considered one of the most polluted cities in Latin America, reached the best air quality in 2023 since records exist, even below the pandemic. Constant monitoring, the electrification of public transport and the promotion of electric heating to replace firewood are some of the measures with which the Chilean capital combats pollution.
