Why are air and noise pollution an issue?
Air Pollution – Negative Effects (3/4)
Vehicles, industry, power plants, agriculture, households, and waste contribute to Europe's air pollution. Emissions of the main air pollutants in Europe have declined in recent decades, resulting in generally improved air quality across the region. However, certain sectors (for example, fine particulate matter (PM2.5)) have not followed this trend, and have seen emissions of some pollutants increase.
