4 Protocol bij het Verdrag van 1979 betreffende grensoverschrijdende luchtverontreiniging over lange afstand, inzake de beheersing van emissies van vluchtige organische stoffen of hun grensoverschrijdende stromen

Classification of volatile organic compounds (VOCs) based on their photochemical ozone creation potential (POCP)

Different photochemical model calculations indicate that substantial reduction of VOCs and NOX emissions are necessary (order of magnitude above 50% in order to achieve significant ozone reduction). Moreover the maximum concentrations of ozone near the ground are reduced in a less than proportional way when VOC emissions are reduced. This effect is shown in principle by theoretical scenario calculation. When all species are reduced by the same proportion, maximum ozone values (above 75 ppb hourly average) in Europe are reduced depending on the existing ozone level by only 10-15% if the mass of non-methane man-made VOC emissions is reduced by 50%. By contrast, if emissions of the most important (in terms of POCP and mass values or reactivity) non-methane man-made VOC species were reduced by 50% (by mass), the calculated result is a 20-30% reduction of peak episodic ozone concentration. This confirms the merits of a POCP approach to determine priorities for VOC emission control and clearly shows that VOCs may at least be divided into large categories, according to their importance in episodic ozone formation.
