Compliance with EU air quality limit values - A first set of sensitivity and optimization analyses

摘要: This report provides additional information to the baseline and optimized scenarios that have been developed for review revision of Thematic Strategy on Air Pollution in TSAP Reports #6 #7. The examines implications different assumptions implementation Euro-6 emission standards light duty diesel vehicles compliance with NO2 air quality limit values Europe. For TSAP-2012 scenario, i.e., a decline real-driving two stages down 1.5 times value test cycle 2018, it is estimated almost all AIRBASE stations modelled this exercise would achieve by 2030 at latest. However, least optimistic sensitivity case, under assumption failure (no change emissions compared Euro-4), about 100 out 1173 monitoring still remain non-compliance 2030. A second analysis optimization results presented Report #7 more detail provides, each scenarios, sectors which reductions occur cost-optimal cases. These will lead lower background pollution concentrations Europe, affect PM10 levels within cities. It estimated, e.g., high ambition number robustly 20%. The seems possible but not certain fall 30% baseline. In contrast, do yield significant improvements values, as series did consider further measures road vehicle emissions. Finally, an initial assessment current future mercury Europe suggests Hg 22% 2020 (relative 2005), mainly consequence coal use power sector. Full available technical controls, especially reduce PM emissions, could eliminate EU another third, so total release be than 50% 2005.
