Air pollution - Drivers & Pressures
What are the related drivers and pressures?
A major driver for the emission of air pollutants, especially for NOx, PM10 and NMVOC is traffic, and to some extent also energy production (see also Figure 12). Since the late 1990s, passenger transport vehicle kilometres of private cars and aviation have shown a strong increase (Figure 10). Freight transport has shown an even more pronounced increase (Figure 11). Since 1990, freight transport (in tonnes kilometres) has tripled. The increase in passenger and freight transport has partly compensated the effect of emission reduction measures.
