Scenarios of Future Development

The prime objective for projecting the development of ozone precursor emissions for a future year was to assess the impacts of policies and legislation in place or in pipeline and to estimate the scope of the ozone problem under these conditions. The projection has to serve a number of purposes, mainly to provide the emission database to calculate ozone concentrations on regional and local scale in the trend year 2010,define a trend scenario, taking into account the legislative and technological framework and thus setting the options and limitations for further emission abatement activities,allow to assess efficiency of already implemented measures in terms of cost-effectiveness and ability to achieve the indicated targets, and finallyto model the effects of structural and behavioural changes on the environmental problem under investigation.
