Indicator Assessment Exposure of ecosystems to acidification, eutrophication and ozone (CSI 005) - Assessment published Dec 2013
Eutrophication The magnitude of the risk of ecosystem eutrophication and its geographical coverage has diminished only slightly over the years. The predictions for 2010 and 2020 indicate that the risk is still widespread over Europe. This is in conflict with the EU's long-term objective of not exceeding critical loads of airborne acidifying and eutrophying substances in sensitive ecosystem areas (National Emission Ceilings Directive, 6th Environmental Action Programme, Thematic Strategy on Air Pollution). Acidification The situation has considerably improved and it is predicted to improve further. The interim environmental objective for 2010 (National Emission Ceilings Directive) will most likely not be met completely. However, the European ecosystem areas where the critical load will be exceeded is predicted to have declined by more than 80 % in 2010 with 1990 as a base year. By 2020, it is expected that the risk of ecosystem acidification will only be an issue at some hot spots, in particular at the border area between the Netherlands and Germany. Ozone Most vegetation and agricultural crops are exposed to ozone levels exceeding the long term objective given in the EU Air Quality Directive. A significant fraction is also exposed to levels above the 2010 target value defined in the Directive. Compared to 2009, the ozone indicators show a mixed behavior  Averaged over all rural background stations, the concentration relevant for the exposure of crops is slightly higher. However, the agricultural area exposed to concentrations above the target value did not increase in 2009 and 2010 compared to previous years, but the area exposed to levels between 12 000 and 18 000 (µg/m 3 ).hour is larger than in the previous years. With respect to the exposure of forests, the concentrations are similar compared to previous years. The effect-related concentrations, addressing exposure of crops to ozone over several summer months, show large year-to-year variations. Over the period 1996-2010 there is a tendency to increased exposure until 2006; and a tendency to decreasing levels after 2006. However, due to the large year-to-year variations, this development has not proven to be statistically significant.

Figure Exposure of agricultural area to ozone (exposure expressed as AOT40 in (μg/m³).h) in EEA member countries
Exposure of agricultural area to ozone (exposure expressed as AOT40 in (μg/m3).hour) in EEA member countries . In the Air Quality Directive (2008/50/EC) the target value for protection of vegetation is set to 18000 (μg/m3).h while the long-term objective is set to 6000 (μg/m3).hour. Until 2006 Iceland, Norway Switzerland and Turkey have not been included in the analyses due to lack of detailed land cover data and/or rural ozone data, in 2007 Switzerland and Turkey are not included; since 2008 only Turkey is not included

Please consider that since 2004 a growing number of member countries has been included. In 2004 Bulgaria, Greece, Iceland, Norway, Romania, Switzerland, and Turkey have not been includedwere added. In For 2005/2006 Iceland, Norway Switzerland and Turkey are were still excluded in the analyses due to lack of detailed land cover data and/or rural ozone data. In 2007 Switzerland and Turkey are were not included. Since 2008 only Turkey is has not beennot included. Calculations of forest exposure are not available for year prior to 2004.

Highlight D source code Black carbon: Better monitoring needed to assess health and climate change impacts
Black carbon is an air pollutant which harms human health and can contribute to climate change – so cutting emissions may have many benefits. The European Environment Agency (EEA) has published a report on the measurement of black carbon in the air.

Daviz Visualization Concentration status for the target value threshold for protection of forests, 2011
Distribution of rural stations by thresholds of AOT40 concentrations for the year 2011. AOT40 concentrations for the protection of forest is the accumulated dose of hourly concentrations of O3 over a threshold of 40 ppb, equivalent to 80 μg/m3, accumulated over five month (April to September).

Daviz Visualization Concentration status for the target value threshold for protection of crops, 2011
Distribution of rural stations by thresholds of AOT40 concentrations measured in stations for the year 2011. AOT40 concentrations for the protection of vegetation is the accumulated dose of hourly concentrations of O3 over a threshold of 40 ppb, equivalent to 80 μg/m3, accumulated over three month (May to July).

Daviz Visualization Concentration status for the target value threshold for protection of human health, 2011
Distribution of stations by thresholds of the 93.15 percentile of the daily maximum of the running 8-h mean O3 concentrations for the year 2011. The chart is based on the 93.15 percentile of the daily maximum of the running 8-h mean O3 concentrations, corresponding to the 26th highest O3 concentration when data availability is 100% over the year.

Press Release Troff document Front-running cities changing transport, improving quality of life
Many cities in Europe are changing, according to a new report which points to rapid transformations in urban transport in some areas. While cycling and efficient public transport are becoming the norm in some urban areas, Europe’s transport sector is still a major contributor to excessive levels of greenhouse gases, air pollution and noise, the report says.
