Too hight levels
Rotterdam does not stand alone when levels, set by the European Union for maximum emission of fine dust as well as for CO2 are passed. Nearly all bigger cities like Amsterdam, Utrecht and The Haque are encountering the same problems. This means that the EU can present a penalty fee which can easily be over millions of Euros.
Levels to control
Those emissions are caused by the many fossil fuel driven cars which are driving mostly slowly or are standing still. Due to the high emissions and fine dust the levels of CO2 and fine dust are very high and such dust particles are inhaled by the people living in the innercity. Both are causing global warming as well as lung diseases.
