Following Tuesday's announcement, Delhi enforced the entry ban on non-BS-VI private vehicles from outside the city and 'No PUC, No Fuel' rule on December 18, 2025. AQI soared to 356-358 in 'very poor' category amid dense fog slashing visibility to 100m, disrupting flights and trains, though winds may aid dispersion later.
La qualità dell'aria a Città del Messico e nello Stato del Messico è migliorata, evitando l'attivazione di una nuova contingenza per l'ozono nel mezzo di un'ondata di caldo. Alle 15:00, solo la stazione di Tlalpan segnalava una qualità scarsa, Cuajimalpa una qualità buona e le restanti una qualità accettabile. La Commissione Ambientale della Megalopoli (CAMe) ha revocato la contingenza del fine settimana e mantiene le allerte per le condizioni di stabilità atmosferica.

Nearly one in 10 homes tested in the UK, Italy and the Netherlands showed benzene levels from gas cooker leaks that surpass safety limits, according to researchers. The cancer-causing chemical in natural gas poses risks akin to secondhand smoke indoors. The findings highlight potential indoor air pollution from slow leaks.
Delhi's air quality has improved sharply, with the average AQI reaching 271 in the poor category, down from severe levels in previous days.

Attacks in the Red Sea forced ships to detour around the Cape of Good Hope, creating a natural experiment that revealed how cleaner marine fuels reduce cloud formation. Researchers found that low-sulfur fuels cut the cloud-boosting effect from ship emissions by about two-thirds. This discovery helps refine climate models and highlights trade-offs in pollution regulations.
