Heavy metals accumulate in ecosystems and damage human health. In line with the EU’s commitments under the Air Convention, specific legislation led to reductions in emissions of heavy metals across Europe from 1990 levels. Between 2005 and 2019, emissions have continued to decline, with lead emissions decreasing by 44%, mercury emissions by 45% and cadmium emissions by 33% across the EU-27 Member States. In 2019, Germany, Italy and Poland contributed most to heavy metal emissions in the EU.
In 2020, the EU continued to actively phase out ozone-depleting substances (ODS), in line with its commitment under the Montreal Protocol. Data for 2020 show that consumption of ODS in the EU remained negative (-2,023 metric tonnes), meaning that more substances were destroyed or exported than were produced or imported. The EU´s consumption of these substances has been negative since 2012.

Between 2010 and 2019, industrial releases to Europe’s water bodies of pollutants that are damaging to human health and the environment declined overall. Releases of heavy metals declined significantly, while emissions of nitrogen and phosphorus, which cause eutrophication, declined to a lesser extent. In the same period, the economic value of industry increased by 14%, in line with the EU policy objective of supporting industrial growth while decreasing industrial emissions. However, data gaps make it difficult to assess industry’s contribution to overall water pollution in Europe.
Industrial releases of air pollutants that are damaging to human health and the environment decreased between 2010 and 2019 in Europe, with emissions of greenhouse gases (e.g. CO 2 and sulphur oxides) and other pollutants (e.g. nitrogen oxides, dust and heavy metals) all declining significantly. The value that industry generated for the European economy during this period increased, however, in line with the goal of the EU industrial strategy: to support the competitiveness of European industry while driving a reduction in emissions, the use of natural resources and the production of waste.
Between 2004 and 2019, emissions from large combustion plants in the EU decreased: SO 2 by 89%, nitrogen oxides by 60% and dust by 88%. Declines in emissions and improvements in environmental performance were largely driven by European policy, which sets legally binding emission limit values. The amount of fossil fuels used decreased by 23%, as energy production shifts to climate-friendly sources. Stricter emission limit values and policies aimed at increasing the use of renewable or cleaner fuels are expected to drive further declines in combustion plant emissions in coming years.
Since 1990, emissions of persistent organic pollutants (POPs) decreased in the EEA-33 countries, e.g. hexachlorobenzene (HCB) decreased by 95 %, polychlorinated biphenyls (PCBs) by 75 %, dioxins and furans by around 70 % and polycyclic aromatic hydrocarbons (PAHs) by 83 %.
The majority of countries report that POP emissions fell during the period 1990 to 2017.
In 2017, the most significant sources of emissions included the ‘Commercial, institutional and households’ and ‘Industrial processes and product use’ sectors.
Local soil contamination in 2011 was estimated at 2.5 million potentially contaminated sites in the EEA-39, of which about 45 % have been identified to date. About one third of an estimated total of 342 000 contaminated sites in the EEA-39 have already been identified and about 15 % of these 342 000 sites have been remediated. However, there are substantial differences in the underlying site definitions and interpretations that are used in different countries.
Four management steps are defined for the management and control of local soil contamination, namely site identification (or preliminary studies), preliminary investigations, main site investigations, and implementation of risk reduction measures. Progress with each of these steps provides evidence that countries are identifying potentially contaminated sites, verifying if these sites are actually contaminated and implementing remediation measures where these are required. Some countries have defined targets for the different steps.
Thirty of the 39 countries surveyed maintain comprehensive inventories for contaminated sites: 24 countries have central national data inventories, while six countries, namely Belgium, Bosnia-Herzegovina, Germany, Greece, Italy and Sweden, manage their inventories at the regional level. Almost all of the inventories include information on polluting activities, potentially contaminated sites and contaminated sites.
Contaminated soil continues to be commonly managed using “traditional” techniques, e.g. excavation and off-site disposal, which accounts for about one third of management practices. In-situ and ex-situ remediation techniques for contaminated soil are applied more or less equally.
Overall, the production sectors contribute more to local soil contamination than the service sectors, while mining activities are important sources of soil contamination in some countries. In the production sector, metal industries are reported as most polluting whereas the textile, leather, wood and paper industries are minor contributors to local soil contamination. Gasoline stations are the most frequently reported sources of contamination for the service sector.
The relative importance of different contaminants is similar for both liquid and solid matrices. The most frequent contaminants are mineral oils and heavy metals. Generally, phenols and cyanides make a negligible overall contribution to total contamination.
On average, 42 % of the total expenditure on the management of contaminated sites comes from public budgets. Annual national expenditures for the management of contaminated sites are on average about EUR 10.7 per capita. This corresponds to an average of 0.041 % of the national GDP. Around 81 % of the annual national expenditures for the management of contaminated sites is spent on remediation measures, while only 15 % is spent on site investigations.
It should be noted that all results derive from data provided by 27 (out of 39) countries that returned the questionnaire, and not all countries answered all questions.
