Poznań's air quality faces winter challenges from residential coal and wood burning generating elevated PM2.5, similar to other Polish cities, alongside vehicle traffic on the surrounding expressway network. The flat Greater Poland plain provides reasonable wind dispersal on most days, while the Warta river corridor provides a natural ventilation pathway through the city. Poznań's coal dependency is gradually decreasing as district heating transitions to cleaner fuels.
