The Natura 2000 legislation, notably with its habitats-test (or: habitats assessment, Article 6 of the Habitats Directive), dates back to the days climate change was not an issue and the concept of ecosystem services had not been well developed. Hence, in international law literature Kistenkas raised the question the habitats assessment was originally not designed for striking a balance of all relevant ecosystem services or to involve climate change into the assessment. Although well protecting nature conservation objectives, a rethinking of the habitats assessment might be necessary in the light of a new climate law as part of e.g. the EU Green Deal.
