Answer given by Mr Sinkevičius

on behalf of the European Commission


The Commission is not aware of and not involved in the development of the study mentioned by the Honourable Member but is ready to look at its results when finalised. The Commission has also conducted a technical study on this matter that may be of assistance to national authorities and stakeholders[1].

In relation to the possible environmental impacts of solar farms projects, the Commission recalls that Member States’ competent authorities need to assess them and ensure that permits for their development are granted in accordance with EU environmental legislation. They have to determine whether solar farms projects need to be subject to an environmental impact assessment because of their likely significant effects on the environment, taking into account the relevant criteria in the Environmental Impact Assessment Directive[2]. Moreover, if solar farm projects are likely to have a significant effect on a Natura 2000 site, an appropriate assessment needs to be undertaken according to Article 6(3) of the Habitats Directive[3]. The authorities can only agree to a project if it will not adversely affect the integrity of the site concerned, either alone or in combination with other plans or projects. In addition, solar farm projects also need to comply with the relevant requirements of the Birds[4] and Habitats Directives related to species protection[5].
