Through a review of published studies and new analyses of publicly available data, the authors assess how the European Union (EU) Nature Directives complements the CBD strategic goals for 2020 as set out in the 20 Aichi Targets, thereby addressing a question posed by the European Commission about the coherence of the Directives with other international biodiversity commitments.

The authors find evidence that the Directives complement several Aichi Targets and other Multilateral Environmental Agreements (MEAs). For example, 92% of the EU's Important Bird and Biodiversity Areas (IBAs), many of them otherwise unprotected, are partly or wholly covered by the Natura 2000 network of protected areas (contributing to Aichi Target 11). Species listed on Annex I of the Birds Directive have fared better than other species (Aichi Target 12). As 65% of EU citizens live within 5 km of a Natura 2000 site, and 98% within 20 km, these sites have the potential to raise awareness of biodiversity (Aichi Target 1) and to deliver ecosystem services to a high proportion of the EU's population (Aichi Target 14).

The Nature Directives provide a regulatory framework that, with fuller implementation, will help EU Member States to meet their obligations under the CBD and other MEAs.
