The quality level of geographical representativity can be considered “good,” the quality level of technical representativity can be considered “good,” and the temporal representativity can also be considered “good.” Therefore, the overall data quality for this EPD can be classified as “good.”
The owner of this EPD shall be liable for the underlying information and evidence. The programme operator Kiwa-Ecobility Experts, third party verifier shall not be liable with respect to manufacturer data, life cycle assessment data and evidence.
To ensure comparability of results, only consistent background data from the ecoinvent database version 3.9.1 was used in the life cycle assessment (e.g. datasets for energy, transport, auxiliary and operating materials), which refer to the reference year 2022. The database is regularly reviewed and thus meets the requirements of EN 15804 (background data not older than 10 years). All consistent datasets contained in the ecoinvent database are documented and can be accessed in the ecoinvent online documentation.
This EPD is developed in accordance with EN 15804. It follows the Polluter Pays Principle, assigning environmental impacts to the responsible entity. It also applies the Modularity Principle, ensuring that impacts are reported in the specific life cycle stage in which they occur, supporting transparency, accountability, and comparability across product systems. |
