Indicator Assessment Oxygen consuming substances in rivers (CSI 019/WAT 002) - Assessment published Feb 2015
Concentrations of biochemical oxygen demand (BOD) and total ammonium have decreased in European rivers in the period 1992 to 2012 (Fig. 1), mainly due to general improvement in waste water treatment.

Indicator Assessment Nutrients in freshwater (CSI 020/WAT 003) - Assessment published Feb 2015
Since 2005, average nitrate concentrations in European groundwater have declined and in 2011, the mean concentration had almost returned to the 1992 level. The average nitrate concentration in European rivers declined by 0.03 milligrams per liter of nitrogen (mg N/l) (0.8%) per year over the period 1992 to 2012. The decline in nitrate concentration reflects the effect of measures to reduce agricultural inputs of nitrate, as well as improvements in wastewater treatment. Average orthophosphate concentration in European rivers has decreased markedly over the last two decades (0.003 milligrams per liter of phosphorous (mg P/l) or 2.1% per year). Also, average lake phosphorus concentration decreased over the period 1992-2012 (0.0004 mg P/l, or 0.8% per year). The decrease in phosphorus concentration reflects both improvements in wastewater treatment and the reduction of phosphorus in detergents.

Indicator Assessment Passenger transport demand (CSI 035/TERM 012) - Assessment published Dec 2014
Passenger transport demand in the EU-28 decreased by nearly 1.5 % between 2011 and 2012, following a slight downward trend since its peak in 2009, broken only by a 1 % increase in 2011. Car passenger travel remains the dominant mode, with a share well above 70 %. Air transport grew by 10 % in 2011, but stabilised in 2012. However, it retained its pre-crisis modal share (9 %). Rail passengers’ share has grown slightly in recent years, and accounted for 7 % in 2012, after the slight increase in the last two years (2011 and 2012). Land passenger transport demand in non-EU-28 countries kept  growing overall in 2012, with a 1.7 % growth in Iceland, and 1.5 % in Switzerland. Norwegian land transport demand figures remain stable, with car and rail demand growth (1.3 % and 3.6 % respectively) offsetting a 20.2 % loss in rail. The quick deterioration of rail passenger transport in Turkey (-22 % in 2012) was accompanied by a significant increase (6.2 % in 2012) in total land transport demand, sustained by a 10.5 % growth in car travel. It is worth noting that, according to Eurocontrol (Eurocontrol, 2014), Turkey is also the main driver of air passenger traffic growth in the European skies.

Indicator Assessment Global and European temperature (CSI 012/CLIM 001) - Assessment published Aug 2014
Global Three independent long records of global average near-surface (land and ocean) annual temperature show that the decade between 2004 and 2013 was 0.75 °C to 0.81 °C warmer than the pre-industrial average. The rate of change in global average temperature has been close to the indicative limit of 0.2°C per decade in recent decades. Variations of global mean near-surface temperature on decadal time scales are strongly influenced by natural factors. Over the last 10-15 years global near-surface temperature rise has been slower than in previous decades. This recent slow-down in surface warming is due in roughly equal measure to reduced radiative forcing from natural factors (volcanic eruptions and solar activity) and to a cooling contribution from internal variability within the climate system (the redistribution of heat to the deeper ocean). The Arctic region has warmed significantly more rapidly than the global mean, and this pattern is projected to continue into the future. The best estimate for further rises in global average temperature over this century is from 1.0 to 3.7°C above the period 1971-2000 for the lowest and highest representative concentration pathway (RCP) scenarios. The uncertainty ranges for the lowest and highest RCP are 0.3–1.7°C and 2.6–4.8°C, respectively. The EU and UNFCCC target of limiting global average temperature increase to less than 2°C above the pre-industrial levels is projected to be exceeded between 2042 and 2050 by the three highest of the four IPCC scenarios (RCPs). Europe Annual average temperature across the European land areas has warmed more than global average temperature, and slightly more than global land temperature. The average temperature for the European land area for the last decade (2004–2013) is 1.3°C above the pre-industrial level, which makes it the warmest decade on record. Annual average land temperature over Europe is projected to continue increasing by more than global average temperature over the rest of this century, by around 2.4 °C and 4.1 °C under RCP4.5 and RCP8.5 respectively. Extremes of cold have become less frequent in Europe while warm extremes have become more frequent. Since 1880 the average length of summer heat waves over western Europe doubled and the frequency of hot days almost tripled.

Indicator Assessment Emissions of primary PM2.5 and PM10 particulate matter (CSI 003/APE 009) - Assessment published Jun 2014
Total emissions of primary sub-10µm particulate matter (PM 10 ) have reduced by 24% across the EEA-33 region between 1990 and 2011, driven by a 35% reduction in emissions of the fine particulate matter (PM 2.5 ) fraction. Emissions of particulates between 2.5 and 10 µm have reduced by 12% over the same period; the difference of this trend to that of PM 2.5  is due to significantly increased emissions in the 2.5 to 10 µm fraction from 'Road transport' and 'Agriculture' (of 20% and 6% respectively) since 1990. Of this reduction in PM 10  emissions, % has taken place in the 'Energy Production and Distribution' sector due to factors including the fuel-switching from coal to natural gas for electricity generation and improvements in the performance of pollution abatement equipment installed at industrial facilities.

Indicator Assessment Emissions of ozone precursors (CSI 002/APE 008) - Assessment published Jun 2014
Emissions of the main ground-level ozone precursor pollutants have decreased across the EEA-33 region between 1990 and 2011; nitrogen oxides (NO X ) by 44%, non-methane volatile organic compounds (NMVOC) by 57%, carbon monoxide (CO) by 61%, and methane (CH 4 ) by 29%. This decrease has been achieved mainly as a result of the introduction of catalytic converters for vehicles, which has significantly reduced emissions of NO X  and CO from the road transport sector, the main source of ozone precursor emissions. The EU-28 as a whole reported 2011 emissions at 4% below the 2010 NECD ceiling for NO X , one of the two ozone precursors (NO X  and NMVOC) for which emission limits exist under the EU's NEC Directive (NECD). Total NMVOC emissions in the EU-28 were 22% below the 2010 NECD limit in 2011, however, seven of individual Member States did not meet their ceilings for one or both of these two pollutants. Of the three non-EU countries having emission ceilings for 2010 set under the UNECE/CLRTAP Gothenburg protocol (Liechtenstein, Norway and Switzerland), all reported NMVOC emissions in 2011 that were lower than their respective ceilings, however Liechtenstein and Norway reported 2011 NO X  emissions higher than their ceiling for 2010.
