The document discusses measures to reduce NO2 levels in Austria. It notes that exceedances of NO2 levels have occurred near roads and highways. The highest levels are found in large cities close to traffic. NO2 comes primarily from diesel vehicles. Projections show NO2 levels from traffic declining slowly by 2020. Measures discussed to reduce NO2 include reducing traffic volume, changing to less polluting vehicles, lowering emission levels from vehicles, and restricting or relocating emissions. Examples given are low emission zones, sectoral bans of trucks, taxes and charges, and speed limits. Both synergies and antagonisms between NO2 reduction and reducing other pollutants are addressed.

- 9. Types of measures to reduce (traffic) volume (activity) to change type of vehicles, installations (emission factors) to change emission factors of vehicles, installations to re-allocate emissions either spatially or temporally to confine emissions 9
- 10. Reduction of traffic volume Congestion charge Parking schemes Increase of taxes and charges, road pricing Sectoral ban (Inn valley motorway) Encouragement of public transport, bicycles, walking, ... ... Source: wikipedia Source: LERK 10

Type of vehicles, machinery Source: paultan.org Stimulating change of vehicle fleet by: incentives to foster uptake of new EURO standards, EEVs (e.g. by differentiating taxes/charges) incentives for gas, electric, ... vehicles increase of tax on diesel Scrappage schemes Environmental zones, ban of certain vehicles, machinery Encourage/require use of electric machinery instead of gasoline driven 11
- 12. Reduction of emissions at source Traffic Speed limit for passenger cars Remote sensing to detect high emitting vehicles Reduction of idling of cars and trucks Traffic, off-road, stationary Selective Catalytic Reduction SCR (retrofitting, e.g. for ships, locomotives, stationary sources) shore-side electricity for ships Auxiliary Power Unit (APU) limitations, use of Ground Power Unit change of fuel (lower N-content) Residential heating district heating, new installations, Combined Heat and Power Production CHP, thermal insulation, ... 12

- 17. Antagonistic measures GHG reduction, increase of NOx Increased use of biomass, some biofuels (when w/o changeover) (Increased share of Diesel)* Carbon capture and storage PM reduction, increase of NOx Diesel particle filter (in some cases; esp. increase of primary NO2) Source: http://www.ornl.gov/info/ornlreview/v33_2_00/research.htm NOx reduction, increase of GHG SCR, SNCR might lead to small decrease of efficiency (not for traffic!) increased use of natural gas (CH4 ) * thwarted by increased weight, power of diesel vehicles 17 Source: BMW
- 18. Synergies In general, synergies with GHG, PM reduction can be expected Reduction of costs to achieve environmental targets due to climate & energy package IIASA 2007, NEC report #5 costs C&EP costs TSAP 18

Speed limits for passenger cars motorways in AT, ES, NL, ... reduction e.g. from 130/120 to 100 or 80km/h side effects: less noise, GHG, accidents, injuries source: Air Quality Plans Technical Office. Environment and Housing Department. Autonomous Government of Catalonia Rotterdam, Inn valley: -3 to -5 g/m³ NO2 Enforcement decisive Inner-city effect (30km/h) small 23
- 24. NO2 level dependent speed limit (AT) Reason: political and public acceptance Reduction v(cars) from 130km/h to 100km/h Dependent on dispersion conditions, number and emissions of cars Same effect of permanent speed limit during winter, 75% of whole year High share of diesel cars high share for NO2 levels Costs: 2–5 Mio. €, if display necessary (permanent speed limit more cost effective) Quelle: Ökoscience 2007 24
- 25. Retrofitting SCR retrofitting possible for HDV, buses, off-road Has to be customized for each application, in some cases for each bus line High reduction of NOx (40-90%) possible Costs: LDV ≈3,500€ HDV ≈ 10,000€ Retrofitting not feasible for passenger cars 25
- 26. Pilot projects for construction sites (AT) charge dependent on EURO standard and transport distance transport via rail, ships recycling of waste at site problem: higher costs of rail transport, public procurement laws, EU law (particle filters) guidance documents (similar to Swiss guidance) © M. Deweis 26
- 27. impact of projects for construction sites charge dependent on EURO standards, distance 85 % EURO III (2005–2006) -75 % HDV km recycling of waste at site -35 % HDV trips 27
- 29. challenges in Austria Compliance with LVs in 2011 and 2015, time extension NO2 large gap in some areas drastic (traffic) measures necessary hardly any reduction of NO2 levels (primary NO2 emissions, diesel-cars, type approval cycle) quantification of impact of measures political and public acceptance exemptions for certain vehicles, installations fragmentation of responsibility compliance with NEC 29
- 30. Summary & conclusions (diesel) cars are dominant source for NO2 exceedances No single measure will result in compliance in many areas In some areas in Europe, even EURO 6/VI will not result in compliance until 2020 CC measures support AQ, leads to a reduction of costs for AQ, even though some measures do have an antagonistic effect. Impact assessment might be necessary Retrofitting not possible for all types of vehicles 30
