    Ammonia emissions

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

    Change in species diversity as a result of climate change — outlook from EEA

    The objective of this indicator is to produce a high-level generic indicator that will show the state and trends of biodiversity in Europe.

    Critical load exceedance for nitrogen

    Exceedance of critical loads for nitrogen deposition indicating risks for biodiversity loss in (semi)-natural ecosystems.

    Ecological Footprint

    The Ecological Footprint represents the productive area required to provide the renewable resources humanity is using, as well the area required to absorb the waste emitted.

    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.

    Emissions of primary particulates — outlook from LRTAP

    This indicator tracks trends and presents projections in emissions of primary particulate PM10 and PM2,5.
    "PM10" means particulate matter which passes through a size-selective inlet with a 50 % efficiency cut-off at 10 mm aerodynamic diameter;
    "PM2,5" means particulate matter which passes through a size-selective inlet with a 50 % efficiency cut-off at 2,5mm aerodynamic diameter.

    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.

    Exceedance of air quality limit values in urban areas

    The indicator shows the fraction of the EU-28 urban population that is potentially exposed to ambient air concentrations of certain pollutants (PM2.5, PM10, O3, NO2, SO2 and B(a)P)) in excess of the EU limit or target values (EU, 2004, 2008) set for the protection of human health; and to concentrations of these pollutants in excess of the WHO Guidelines (WHO, 2000, 2006).

    It also shows the evolution of urban background levels of PM2.5, PM10, O3 and NO2 at the European level.

    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."

    Land cover distribution and change — outlook from MNP

    Land cover distribution and change is a modeled prediction of the distribution of land-cover types (tropical rain forest; desert; tundra; etc.) across the total world terrestrial area in 2050 based on different scenarios.

    Municipal waste generation, total

    Total Municipal waste consists of waste generated by households primarily, but may also include similar wastes generated by small businesses and public institutions and collected by the municipality.

    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.

    Status of marine fish stocks

    "The indicator tracks the ratio of the number of over-fished stocks to the total number of commercial stocks per fishing area in European seas."

    Domestic material consumption by material

    The indicator Domestic Material Consumption (DMC) is defined as the total amount of material directly used in an economy. DMC equals Direct Material Input (DMI) minus exports and Domestic Extraction (DE) plus imports. (source: Eurostat,
