The non-linear chemistry, responsible for ozone formation poses problems in developing an optimized abatement strategy. Estimates of emissions are often quite uncertain, e.g. in estimates of biogenic emissions and car emissions. Effective abatement should be based on a careful evaluation of local conditions regarding oxidant formation. Some control strategies are effective in one place, but not in another. A good example offers control by means of limiting of hydrocarbons. This strategy is not effective in regions where large emissions of biogenic hydrocarbons are encountered.
