Additional policy instruments are needed to achieve Swedish environmental quality objectives for maritime transport

Achieving the national and international environmental objectives for maritime airborne emissions requires a combination of new and more powerful policy instruments. The policies already in place are not enough. This is one of the conclusions of a research project, led by VTI, which has now been...

Properly Placed Vegetation in Cities Improves Air Quality

Vegetatation in city environment.
A city’s vegetation can affect its air quality both positively and negatively. The positive effect is that the total amount of air pollution decreases because the air is being filtered. On the other hand, vegetation in crowded street canyons can degrade the air locally if deployed in such a way...
