Metrics for material sub-topics of E4 Biodiversity and Ecosystems

Revised ESRS 2026

ESRS Standard

20. In addition to paragraph 19, and in accordance with ESRS 2 GDR-M, the undertaking shall report metrics related to its material impacts on biodiversity and ecosystems.


Application Requirements

AR 9. When providing the description of material impacts in accordance with ESRS 2 IRO-2, the undertaking shall indicate which material impacts concern land degradation, desertification or soil sealing and operations that affect threatened species or ecosystems.

AR 10. Depending on which sub-topic is material, the undertaking shall

include metrics in relation to:

(a) drivers of biodiversity and ecosystem change,

(b) the state of species (e.g. related to extinction risk),

(c) the condition and extent of terrestrial, freshwater, and

marine ecosystems (e.g. related to site condition and

landscape condition) and

(d) ecosystem services.

AR 11. Primary data on the state of nature metrics collected at location-level or through remote sensing is the best means to help determine impacts on biodiversity and ecosystems. Using primary data on the state of nature

is especially relevant where the undertaking’s sites are in or near

biodiversity-sensitive areas. The undertaking can also estimate its

impacts by using data on impact drivers or secondary data on the state of nature.

AR 12. When identifying the metrics to disclose, the undertaking shall

consider:

(a) the frequency of monitoring and the baseline condition or value and baseline year or period; and

(b) whether the metrics enable users to understand how they relate to the

material impacts.


Definitions (ESRS) and further information

Protected area

"A clearly defined geographical space, recognised, designated and managed through legal or other effective means to ensure the long-term conservation of nature and the associated ecosystem services and cultural values."

Simplified wording:
A protected area is a legally defined area where special rules and bans apply. They protect the biological diversity of natural and cultural landscapes, as well as abiotic resources.

Further information and references to protected areas in the Austrian federal states are available on the website of the Federal Environment Agency and in the further sources listed at the end of the article. The interactive map of Austria on Geoland.at shows protected areas in Austria. For example, you can display protected areas under various directives, as well as relevant cultural sites.

Biodiversity-sensitive area

"Areas that include Natura 2000 protected areas, UNESCO World Heritage Sites, Key Biodiversity Areas, and other protected areas"

  1. Natura 2000
    EU-wide network of protected areas for the conservation of habitats and species. It is based on the Birds Directive and the Habitats Directive (Fauna, Flora and Habitats Directive).

  2. Established in the UNESCO Convention concerning the Protection of the World Cultural and Natural Heritage.

  3. Areas of particular ecological value that are identified on the basis of scientific criteria. They have no general legal basis. They are mostly protected by national laws, international agreements or voluntary measures.

  4. Other protected areas

    • Databases and maps of environmental authorities

    • International registers of protected areas
      (e.g. World Database on Protected Areas – WDPA, Protected Planet)

    • National categories of protected areas (e.g. national parks, biosphere reserves, landscape protection areas)

Biodiversity or biological diversity

"The variability among living organisms and the ecological complexes of which they are part, including genetic, phenotypic and functional differences as well as temporal and spatial changes in their distribution."

Simplified wording:

A diversity of life in a habitat is necessary for a stable, productive and resilient ecosystem. This diversity shows in genes, in outward characteristics and in functions. These are not fixed. They can change over time or across space.
