Action plans in Austria

Two step process (according to Austrian law):

1. Identification of relevant sources that caused the exceedances and determination of area affected by low air quality (“status report”)

2. Abatement measures (if possible) to avoid exceedances in future

Results of status reports

PM10 exceedances: status reports finished for Graz, Linz, Klagenfurt, Lienz: mostly caused by traffic and domestic heating, at some sites also influence of local industry and gaseous precursor

NO2 exceedances: status reports for Tyrol, Vienna,

Salzburg: caused to a great extent by traffic.However, to comply with LVs a substantial decrease of traffic (mostly HDVs) would be necessary

Abatement measures

NO2 exceedances in Tyrol:

68% of NO2 emissions from HDV

Action plan: night-time ban (10pm to 6am) of HDV (started a year ago)

Sectoral ban of HDV (iron, waste, wood,…), abandonded by EU-court

Result of night-time ban: counterproductive for compliance with short time LV as all banned vehicles go between 5am and 9am when inversions have not dissolved yet. Influence on annual mean not evaluated yet

Ban should be between 10pm and 10am

PM10 exceedances:

local measures in Linz (industry) and Lienz (domestic heating replacement programs)

Nationwide PM10 abatement strategy will be finished in 2004

Ozone reduction:

First action plans should be finalised in the near future
