To ensure better air quality, the municipalities and cities in which pollution levels are too high are obliged to adopt an air quality plan and define measures for solving the problem. Most of them have not done that yet, according to the data obtained by CINS. However, even in places that do have these plans the quality of air has officially worsened, which CINS’ interlocutors assess differently: either the measures are not being implemented properly or there is not enough money to implement all of them.
