  1. Berlin’s Air Quality Strategy: measures and expected effects Martin Lutz Senate Department for Urban Development, Berlin Directorate IX, Environment Policy • brief recap: problems, origin, sources • expected benefit of a trend scenario • additional measures and their impact

  2. Comparison of PM10-pollution in European cities EU-limit value

  3. 40 35 30 25 20 15 10 urban background Source analysis Simplified schematic of the PM pollution Urban areas countryside Traffic, local sources PM [µg/m³] regional background hemisspheric/natural background

  4. source attribution Sectors contributing to total PM10 at a busy traffic spot in Berlin.... #based on values recorded at the top of a radio tower 324m above ground Institut für Energie- und Umwelttechnik e.V.

  5. street canyon Air pollution control planning in Berlin  multi-scale model calculations ~30x30 km2 4x4 km2 1x1 km2

  6. current situation (base year 2002)  modelled PM10 in street canyons 24h limit value annual limit value • 450 km road sections in non-attainment • 190.000 affected residents

  7. trend scenario 2010 predicted PM10 concentration in main road network 24h limit value annual limit value • 200 km road sections in non-attainment • ca 81.000 affected residents

  8. Air pollution control planning additional measures planned • stationary sources • BAT and more …. • transport: • cleanervehicles and fuels • municipal car fleet (CRT retrofit & CNG) • LEZ (low emission zone) • less traffic through sustainable transport- and city planning (master plan transport, “StEP”), inter alia…. • re-routing through traffic on tangential roads • extension of zones with parking fees • expected effect: ~ 10% traffic reduction in Berlin’s centre • Optimized traffic management at hot spots ( HEAVEN) • linked with noise abatement • Speed limits • big effect on noise and safety • little effect on air quality • stationary sources • BAT and more …. • transport: • cleanervehicles and fuels • municipal car fleet (CRT retrofit & CNG) • LEZ (low emission zone) • less traffic through sustainable transport- and city planning (master plan transport, “StEP”), inter alia…. • re-routing through traffic on tangential roads • extension of zones with parking fees • expected effect: ~ 10% traffic reduction in Berlin’s centre • Optimized traffic management at hot spots ( HEAVEN) • linked with noise abatement • Speed limits • big effect on noise and road safety • little effect on air quality

  9. Options for LEZ: Emission reduction in relation to the trend scenario 2010 impact of transport planning („StEP“) and vehicle technology all Diesel vehicles Euro III + particle filter(PF) all vehicles Euro IV + PF busses Euro V big fleets of delivery services and logistic firms municipal fleet no StEP with StEP no StEP implementation 2010

  10. Air Pollution Control Planning Core measure: low emision zone traffic restriction for high emitting Diesel vehicles in the cenral city area • stage I: 2008, minimum criteria EURO II • stage II: 2010, minimum criteria EURO III & particle filter  scrutiny in 2006, whether retrofit with particle trap could be required already in stage I  at last under preparation... • national labelling scheme for clean vehicles Federal Government • tax incentives, in particular for clean (or retrofitted) vans and lorries Federal Government

  11. Air Pollution Control Planning impact of various control scenarios

  12. 24h limit value annual limit value low emission zone low emission zone LEZ & “StEP” scenario 2010 PM10 reduction beyond the trend scenario 2010

  13. 24h limit value Beusselstr annual limit value remaining hot spots where local traffic management is an option LEZ & “StEP” scenario 2010 predicted PM10 concentration in main road network

  14. Expected decrease of PM10 in Berlin 40 -9% 35 -11% -13% -14% 30 -4% -13% -24% -30% 25 local increment -8% -10% -11% -15% 20 urban increment annual average PM10 [µg/m³] regional BG 15 10 -10% -10% -10% -10% 5 0 2002 CLE 2010 LEZ 2010 LEZ StEP "MFR" 2010 Results of scenario runs

  15. Air Pollution Control Planning supplementary action Optimised traffic management at hot spots • HEAVEN: potential for improvement up to 20% (NOx) and 7% (PM10) by truck ban • limited scope for implementation • needs thorough investigation to avoid disbenefits elsewhere • successive scrutiny of remaining hot spots • Speed limits • concept for imposing 30 km/h limits on main roads where noise & road safety & air pollution warrants
