Rationale

Justification for indicator selection

Persistent Organic Pollutants (POPs), including polycyclic aromatic hydrocarbons (PAHs) are recognised as being directly toxic to biota. They can be progressively accumulated higher up the food chain, such that chronic exposure of lower organisms to much lower concentrations can expose predatory organisms, including humans and wildlife, to potentially harmful concentrations. In humans, POPs are also of concern for human health because of their toxicity, their potential to cause cancer and their ability to cause harmful effects at low concentrations. Their relative toxic/carcinogenic potencies are compound specific. POPs, including PAHs, have also been shown to possess a number of toxicological properties. The major concern is centred on their possible role in carcinogenic, immunological and reproductive effects but more recently concern has also been expressed over their possible harmful effects on human development.

Policy context and targets

Context description

Targeted EC legislation (directives and regulations), coupled with improved control and abatement techniques, have led to strong progress by the EEA-33 countries in reducing air emissions of POPs, including the PAH group of chemicals. Such legislation includes:

  • The 1998 UNECE Aarhus Protocol on POPs (to the 1979 Convention on Long-range Transboundary Air Pollution (LRTAP)). The ultimate objective of this protocal is to eliminate any discharges, emissions and losses of POPs. The original Protocol bans the production and use of some products outright (aldrin, chlordane, chlordecone, dieldrin, endrin, hexabromobiphenyl, mirex and toxaphene), with others scheduled for elimination at a later stage (DDT, heptachlor, hexaclorobenzene, PCBs). In 2009, the protocol was updated to list commercial Pentabromodiphenyl (Penta-BDE) and commercial Octabromodiphenyl (Octa-BDE) as POP substances, whilst the POPs task force concluded that hexabromocyclododecane (HBCD) met the criteria to be considered as a POP, and potential risk management options are therefore currently being considered for it. Finally, the protocol severely restricts the use of DDT, HCH (including lindane) and PCBs, and includes provisions for dealing with the wastes of products that will be banned. It also obliges parties to reduce their emissions of dioxins, furans, PAHs and HCB to below their 1990 levels (or an alternative year between 1985 and 1995). For the incineration of municipal, hazardous and medical waste, it lays down specific limit values.

 

  • The 2001 UNEP Stockholm Convention on POPs aims to reduce and ultimately cease the manufacture, use, storage and emission of POPs, as well as to destroy existing stocks. It provides for measures to reduce or eliminate emissions resulting from intentional and unintentional production and use. It also plans to meet the obligations on technical and financial assistance to developing countries and countries with economies in transition, and to cooperate and exchange information. 12 POPs were covered under the original scope of the Convention:

 

  • Pesticides: aldrin, chlordane, DDT, dieldrin, endrin, heptachlor, hexachlorobenzene, mirex, toxaphene;
  • Industrial chemicals: hexachlorobenzene, polychlorinated biphenyls (PCBs); and
  • By-products: hexachlorobenzene; polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/PCDF), and PCBs.

 

  • In May 2009, nine additional chemicals were added to the Convention:
    • Pesticides: chlordecone, alpha hexachlorocyclohexane, beta hexachlorocyclohexane, lindane, pentachlorobenzene;
    • Industrial chemicals: hexabromobiphenyl, hexabromodiphenyl ether and heptabromodiphenyl ether, pentachlorobenzene, perfluorooctane sulfonic acid, its salts and perfluorooctane sulfonyl fluoride, tetrabromodiphenyl ether and pentabromodiphenyl ether; and
    • By-products: alpha hexachlorocyclohexane, beta hexachlorocyclohexane and pentachlorobenzene

 

Targets

As noted above, the POPs protocol to the UNECE LRTAP Convention obliges parties to reduce their emissions of dioxins, furans, PAHs and HCB below their 1990 levels (or an alternative year between 1985 and 1995 inclusive).

Methodology

Methodology for indicator calculation

This indicator is based on officially reported national total and sectoral emissions to the EEA and UNECE/EMEP (United Nations Economic Commission for Europe/Co-operative programme for monitoring and evaluation of the long-range transmission of air pollutants in Europe) Convention on Long-range Transboundary Air Pollution (LRTAP Convention), submission 2015. For the EU-28 Member States, the data used is consistent with the emissions data reported by the EU in its annual submission to the LRTAP Convention.

Recommended methodologies for emission inventory estimation are compiled in the EMEP/EEA Air Pollutant Emission Inventory Guidebook, (EMEP/EEA, 2013). Base data is available from the EEA Data Service

(http://www.eea.europa.eu/data-and-maps/data/national-emissions-reported-to-the-convention-on-long-range-transboundary-air-pollution-lrtap-convention-9) and the EMEP web site (http://www.ceip.at/). Where necessary, gaps in reported data are filled by the European Topic Centre for Air and Climate Change using simple interpolation techniques (see below). The final gap-filled data used in this indicator is available from the EEA Data Service (http://www.eea.europa.eu/data-and-maps/data/data-viewers/air-emissions-viewer-lrtap).

Indicator specification and metadata

Base data, reported in the UNECE/EMEP Nomenclature for Reporting (NFR14) sector format, is aggregated into the following EEA sector codes to obtain a consistent reporting format across all countries and pollutants:

  • Energy production and distribution: emissions from public heat and electricity generation, oil refining, production of solid fuels, extraction and distribution of solid fossil fuels and geothermal energy;
  • Energy use in industry: emissions from combustion processes used in the manufacturing industry including boilers, gas turbines and stationary engines;
  • Industrial processes: emissions derived from non-combustion related processes such as the production of minerals, chemicals and metal production;
  • Road transport: light and heavy duty vehicles, passenger cars and motorcycles;
  • Non-road transport: railways, domestic shipping, certain aircraft movements, and non-road mobile machinery used in agriculture and forestry;
  • Commercial, institutional and households: emissions principally occurring from fuel combustion in the services and household sectors;
  • Solvent and product use: non-combustion related emissions mainly in the services and households sectors including activities such as paint application, dry-cleaning and other use of solvents;
  • Agriculture: manure management, fertiliser application, field-burning of agricultural wastes;
  • Waste: incineration, waste-water management;
  • Other: emissions included in national totals for the entire territory not allocated to any other sector

Methodology for gap filling

An improved gap filling methodology was implemented in 2010 that enables a complete time series trend for the main air pollutants (NOX, SOX, NMVOC, NH3 and CO) to be compiled. In cases where countries did not report emissions for any year, it meant that gap-filling could not be applied. For these pollutants, therefore, the aggregated data is not yet complete and is likely to underestimate true emissions. Further methodological details of the gap filling procedure are provided in section 1.4.2 Data gaps and gap-filling of the European Union emission inventory report 1990–2009 under the UNECE Convention on Long-range Transboundary Air Pollution (LRTAP).

Uncertainties

Methodology uncertainty

The use of gap filling in instances where countries have not reported emissions for one of more years can potentially lead to artificial trends, but it is considered unavoidable if a comprehensive and comparable set of emissions data for European countries is required for policy analysis purposes.

Data sets uncertainty

Uncertainties in the emission estimates of PAHs reported by countries are considered to be higher than for other more 'traditional' air pollutants such as NOX and SO2 due to the relatively higher uncertainties that exist in both activity data and emission factors for this group of pollutants. Emission estimates for the other POPs are also considered to be of high uncertainty. 

Rationale uncertainty

This indicator is regularly updated by the EEA and is used in state of the environment assessments. The uncertainties related to methodology and data sets are therefore of importance. Any uncertainties involved in the calculation and in the data sets need to be accurately communicated in the assessment, to prevent erroneous messages influencing policy actions or processes.
