    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.

    Damages from weather and climate-related events

    Number of natural disasters
    Overall and insured losses from natural disasters

    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 efficiency and energy consumption in industry

    Specific consumption per tonne produced : Energy consumption divided by the physical production (for steel, cement , paper)

    Energy efficiency index of industry (ODEX) is a weighted average of the specific consumption index of 10 manufacturing branches.

    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.

    Forest growth

    This indicator measures forest area and volume of forest biomass.

    Generation and recycling of packaging waste

    Total packaging used in EU Member States in kg per capita.

    Recycling of packaging waste as a share of packaging used in EU Member States. The amount of packaging used is expected to equal the amount of packaging waste generated because of its short lifetime.

    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 (

    Nationally designated areas

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

    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.

    Soil organic carbon

    Soil organic carbon is the carbon (C) stored in soil organic matter (SOM). Organic carbon (OC) enters the soil through the decomposition of plant and animal residues, root exudates, living and dead microorganisms, and soil biota. SOM is the organic fraction of soil exclusive of nondecomposed plant and animal residues. Nevertheless, most analytical methods do not distinguish between decomposed and non-decomposed residues. SOM is a heterogeneous, dynamic substance that varies in particle size, C content, decomposition rate, and turnover time.

    Species diversity

    Species diversity is a measure of the diversity within an ecological community that incorporates both species richness (the number of species in a community) and the evenness of species' abundances. Species diversity is one component of the concept of biodiversity.
