    Ammonia emissions

    The indicator measures emissions of Ammonia (NH3). It also provides information on emissions by sectors (e.g. Industrial processes; Road transport)

    Biological quality of lakes

    This indicator represents the Cyanobacteria percentage of total phytoplankton biomass. This is an indicator of eutrophication.

    Emission of acidifying substances

    Emissions of organic matter

    The emission of organic matter is a key environmental problem. Among the pollutants mentioned are Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and Total Organic Carbon (TOC). BOD, COD and TOC are key indicators of the oxygen content of water.

    Energy and non-energy related greenhouse gas emissions

    Total man-made emissions of the ‘Kyoto basket’ of greenhouse gases (carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and the so-called F-gases (hydrofluorocarbons, perfluorocarbons and sulphur hexafluoride (SF6)). These gases are aggregated into a single unit using gas-specific global warming potential (GWP) factors.

    Energy-related emissions of particulate matter

    Combination of primary PM10 data, and emissions of secondary PM10 precursors (SO2 and NOx and NH3) weighted using aerosol formation factors (according to de Leeuw, 2002) NOx = 0.88, SO2 = 0.54 and NH3 = 0.64. Gaps in reported data have been filled by EEA/ETC-ACC where necessary using simple interpolation techniques.

    Exposure of ecosystems to acidification, eutrophication and ozone

    "The indicator shows the ecosystem or crops areas at risk of exposure to harmful effects of ozone as a consequence of air pollution, and shows the state of change in acidification, eutrophication and ozone levels of the European environment."

    Forest growth

    This indicator measures forest area and volume of forest biomass.

    Freshwater quality

    This indicator shows:

    1. Annual median concentrations in rivers of Biological Oxygen Demand (BOD) and ammonium (NH4).

    2. Trends in concentrations of orthophosphate and nitrate in rivers, total phosphorus and nitrate in lakes, and nitrate in groundwater bodies.

    Units

    The concentration of nitrate is expressed as mg nitrate (NO3)/l for groundwater and mg nitrate-nitrogen (mg NO3-N/l) for rivers and orthophosphate and total phosphorus as mg P/l.

    Fuel prices

    "The price of fuel in the EU, including the cost price, excise duty and VAT. Prices are in Euros per litre."

    (EEA, http://www.eea.europa.eu/data-and-maps/indicators/fuel-prices-and-taxes, 2014-12-17)

    Global and European temperature

    This indicator shows absolute changes and rates of change in average near-surface temperature for the globe and for a region covering Europe. (Definition of EEA)

    Habitats of European interest

    The indicator shows changes in the conservation status of habitats of European interest.
    It is based on data collected under the reporting obligations of Article 17 of the EU Habitats Directive (92/43/EEC).

    Invasive alien species in Europe

    Number of the listed 'worst' terrestrial and freshwater invasive alien species in each country". (EEA, from the title of figure 4 from http://www.eea.europa.eu/data-and-maps/indicators/invasive-alien-species (http://www.eea.europa.eu/data-and-maps/indicators/invasive-alien-species...)

    Nationally designated areas

    Areas designated under national legislation for the purpose of nature protection including sites such as national parks and nature reserves.

    Nitrogen oxides emissions

    Nitric oxide (NO) and nitrogen dioxide (NO2) are together referred to as nitrogen oxides (NOX). Combustion of fossil fuels is by far the dominant source of NOX emissions. The emissions are not dependent solely on the amount of nitrogen in the fuel but also on the air - fuel mix ratio. High temperatures and oxidation-rich conditions generally favour NOX formation in combustion.NOX contributes to acid deposition and eutrophication which in turn can lead to potential changes occurring in soil and water quality.

    Production and consumption of ozone depleting substances

    This indicator quantifies the production and consumption of ozone-depleting substances (ODS) in Europe. ODS are long-lived chemicals that contain chlorine or/and bromine and that destroy the stratospheric ozone layer.

    The indicator presents production and consumption in units of tonnes of ODS, which is the amount of ODS produced or consumed, multiplied by their respective ozone depleting potential value. The UNEP - Ozone secretariat data are already provided in tonnes of Ozone Depleting Potential (ODP tonnes).

    Soil erosion by water

    EU-wide estimates of erosion are based on modelling studies. Most models contain a rainfall erosivity factor and a soil erodibility factor that reflect average precipitation conditions. Typical values for these factors may inadequately represent the impact of extreme rainfall. Therefore, the uncertainty of modelled erosion risk is high, especially at local level.
