Aarhus, convention
A UN treaty signed on 25 June 1998 by the European Union in the Danish city of Aarhus,
providing for access to information, public participation in decision-making and
access to justice in environmental matters. It is known as the Aarhus convention.
This website is a result of the Aarhus convention [Index]
Catchment area
A catchment area is the area from which surface runoff is carried away by a single
drainage system. In general, this term is used for the area of land bounded by watersheds
draining into a specific river, basin or reservoir. [Index]
Classification in maps
The 9 colour ranges in the maps presented run from light yellow to dark red. This
classification is calculated automatically using the minimal and maximal emission
values. One out of three methods can be used: equal value, equal count and equal
value based on logarithmic values. [Index]
Compartment
Air, water and soil represent the three classical compartments. Two extra compartments
have been added to the Emission register. These are: ‘Air’ and the compartment ‘Air
IPCC’, excluding some national emissions (e.g. emissions from international shipping,
air traffic above a certain level and the use of biofuels). Water has three compartments:
‘Discharged load to surface water’, 'Load to sewers' and ‘Load to sewers and surface
waters’. See also the general
explanation of compartiments
[Index]
Competent authority
The national authority assigned by a member state to validate emissions. In the
Netherlands the provinces validate the emissions to air from the larger facilities.
The municipalities validate the emissions from agriculture. For emissions to water
the competent authority is the local water board assigned to the catchment area;
in the case of large rivers or the sea, the competent authority is the national
government. [Index]
Hydrochlorofluorocarbons(HCFC's)
Ozone-depleting substances taken up in the Montreal Protocol; they comprise hydrogen,
chlorine, fluorine, and carbon. [Index]
Chlorofluorocarbon (CFC's)
Ozone-depleting substances mentioned in the Montreal protocol, consisting of chlorine,
fluorine, and carbon: CFCl3 (CFC-11), CF2CL2 (CFC-12),
C2F3Cl2 (CFC-113), C2F5Cl
(CFC-115), CF3Cl (CFC-13), C2FCl5 (CFC-111), C2F2Cl4
(CFC-112), C3FCl7 (CFC-211), C3F2Cl6
(CFC212), C3F3Cl5 (CFC-213), C3F4Cl4,
(CFC-214), C3F5Cl3 (CFC-215), C3F6Cl2
(CFC-216), C3F7Cl (CFC-217). [Index]
Atmosferic Deposition
The factsheet
atmosferic deposition for the Netherlands and the Netherlands Continental Shelf
describes the method used to calculate deposition on coastal waters. Coastal waters
are defined by a 1 mile distance from shore. This website contains data of all saltwater,
including Waddenzee and Oosterschelde and Westerschelde. [Index]
Diffuse sources
the large number of small and scattered sources which can produce emissions to the
air, soil and water. Their combined effect can be significant but it is not practicle
to report them individually. Within the Dutch emission register every emission source
without an individual emission report is considered to be a diffuse source, including
emissions from transportation, consumers etc. but also emissions from small and medium
sized enterprises [Index]
Direct and indirect emissions (to water)
Direct emissions are emissions direct to the surface water (load to surface water).
Indirect emissions are emissions to the sewer system and sewage treatment plant
(emissions to water). See the
explanation of compartiments
[Index]
Embargosheet
The Dutch Emission Register contains the emissions of more than a hundred components.
But not always all sources are known. Consequently there is no national figure given.
In order to publish as much al possible data we use the so called Embargosheet,
stating the sources without a known emission for a given component [Index]
EMEP
European co-operative programme for Monitoring and Evaluation of the long-range
transmission of air Pollutants [Index]
Emission source
The emission source is the most detailed level for defining emissions on a national
scale. More than a thousand emission sources are summed in a hierarchy of over 100
sub-sectors and 14 sectors. Some emission sources within such sectors as Industry
or Energy have another level below the emissions source: the individual
facilities. [Index]
EPER : European Pollutant Emission Register
EPER is the first European-wide register of industrial emissions to air and water.
It provides access to information on the annual emissions of approximately 12,000
facilities in the 25 member states of the EU and Norway for the year 2004, see the
EPER website It allows you to group information
easily, by pollutant, activity (sector), air and water (direct or via a sewer system)
or by country. It is also possible to see detailed data on individual facilities.
EPER has delivered two datasets: one for 2001 and one for 2004. EPER will be replaced
by E-PRTR (see below).
[Index]
E-PRTR : European Pollution Release and Transfer Register
The European PRTR is the European Pollutant Release and Transfer Register - the
European-wide register of industrial and non-industrial releases into air, water,
land and off-site transfers of waste water and waste, including information from
point and diffuse sources. The first E-PRTR reporting year will be 2007. E-PRTR
replaces EPER. [Index]
Facility
Facility is the formal id for a company or point source. A facility is defined as
an industrial complex with one or more installations on the same site.

Greenhouse gases
Greenhouse gases (GHG) are gaseous components of the atmosphere that contribute
to the greenhouse effect. The major natural greenhouse gases are water vapor, carbon
dioxide (CO2) and ozone. Other greenhouse gases are methane (CH4),
nitrouse oxide (N2O), hydrofluorcarbons (HFC's) and sulfur hexafluoride
(SF6). [Index]
Halonen
Ozone-depleting substances taken up in the Montreal protocol: CF2BrCl,
CF3Br, C2F4Br2, CH3Br.
[Index]
Heavy metals are a group of elements - between copper and lead on the periodic talbes
of the elements - having atomic weights between 63.546 and 200.590 and specific
gravities greater than 4.0. Living organisms require trace amounts of some heavy
metals, including cobalt, copper, manganese and zinc, but excessive levels can be
detrimental to the organism. Other heavy metals such as mercury, lead and cadmium
have no known vital or beneficial effect on organisms, and their accumulation over
time in the bodies of mammals can cause serious illness. [Index]
HFC's
Hydrofluorocarbons, a group of greenhouse gases: HFC23, HFC32, HFC41, HFC4310mee,
HFC125, HFC134, HFC134a, HFC152a, HFC143, HFC143a, HFC227ea, HFC236fa, HFC245ca,
HFC365mfc. [Index]
IPCC : Intergovernmental Panel on Climate Change
The Intergovernmental Panel on Climate Change (IPCC) was established by WMO and
UNEP to assess scientific, technical and socio-economic information relevant for
the understanding of climate change, its potential impacts and options for adaptation
and mitigation [Index]
IPPC : Integrated Pollution Prevention and Control
IIPPC forms the subject matter of Council Directive 96/61/EC of 24 September 1996,
concerning integrated pollution prevention and control, a European Union regulation
which is referred to as the IPPC Directive. [Index]
Method report
A method report describes how the emissions of a specific emission source are calculated.
You can find these reports selecting 'documents' in the menu. Many of them are in
the Dutch. [Index]

Perfluorocarbons (PFC's)
Ozone-depleting substances mentioned in the Montreal protocol. Sum of CF4,
C2F6, C3F8, C4F10,
c-C4F8, C5F12, C6F14.
PFC is 6500-9200 times more effective than carbon dioxide at trapping heat in the
atmosphere. [Index]
Point source
In the Dutch Emission Register a point source is the synonym of a company or facility
with known individual emissions. However, not all the emissions from all the point
sources are known. Point sources without known individual emissions belong therefore
to diffuse sources. [Index]
Spatial allocation
This is the process in which national emissions are allocated to a spatial unit
(e.g. community, province, gridcel or water catchment area). [Index]
