The European Union has been legislating to control emissions of air pollutants and to establish air quality objectives for the last two decades. After many years of a somewhat piece-meal approach, ambient air quality legislation is now being consolidated. Directive 96/62/EC on ambient air quality assessment and management, the so called Air Quality Framework Directive, sets a strategic framework for tackling air quality consistently by setting European-wide limit values for twelve air pollutants in a series of daughter directives. These will supersede and extend existing European legislation. |
