The dataset contains the location of fossil fuel energy production facilities derived from the European Pollutant Release and Transfer Register (E-PRTR). E-PRTR cover all HELCOM Contracting Parties except Russia. Attribute specification and units: See E-PRTR code lists at https://www.eionet.europa.eu/schemas/eprtr/listOfValues In the HELCOM data review process, some facility locations appeared to be spatially slightly misplaced, adding up to uncertainty of data products derived from this dataset.

Locations of the coastal protection structures. The dataset contains information about the coastal defence structure type and for some the structure length (m) and the year of construction. The data was made available by HELCOM Contracting Parties in response to data request. The data was received from Denmark, Estonia, Germany, Finland, Poland and Sweden. The activity was declared as not relevant in Lithuanian area. From Latvia and Russia no data was reported. Attribute specification and units Country: Country Type: Modification structure type Const_year: Year of construction Estimated: Estimated date of completion if under construction (Estonia) or the year of environmental permit if year of construction is lacking (Finland) Out_of_use: Year when costal defence structure has been taken out of use Measure: Additional information about the modification structure Length: Length of the modified coastline (m) width: Width of the modification structure (m) Area: Area of the modification structure (km2) X_Lon: Original X (Longitude) coordinate point (Finland)
