By application lodged on 9 February 2017, Terre wallonne sought the annulment of that decree before the Conseil d’Etat (Council of State, Belgium).

| 16 | In support of its application, that association claimed, inter alia, that the provisions of the Decree of 1 December 2016 come within the scope of the notion of ‘plans and programmes’, for the purposes of either the Habitats Directive or the SEA Directive. According to the association, that notion applies not only to plans and programmes likely to be harmful to the environment but also to those potentially beneficial to the environment. It takes the view, moreover, that the public inquiry ought to have extended to the entire territory of the Walloon Region and not solely to the municipalities affected by the Natura 2000 sites. |

It takes the view, moreover, that the public inquiry ought to have extended to the entire territory of the Walloon Region and not solely to the municipalities affected by the Natura 2000 sites.

| 17 | In reply, the Government of the Walloon Region contends, first, that the Decree of 1 December 2016 is ‘directly linked or necessary’ to the management of the sites, with the effect that it does not come within the scope of the situations referred to in Article 6(3) of the Habitats Directive. Secondly, since that decree is exempt from an appropriate assessment, within the meaning of that directive, it ought also to be exempt from an assessment of its effects, for the purposes of the SEA Directive, Article 3(2)(b) of which refers to Articles 6 and 7 of the Habitats Directive. The Walloon Government adds that that decree does not constitute a plan or programme, for the purposes of the SEA Directive, and does not, in any case, come within the scope of that directive as a result of Article 3 thereof. |

| 18 | The referring court is unclear as to whether the Decree of 1 December 2016 comes within the scope of the SEA Directive and, if so, whether or not the effect of the Habitats Directive is to preclude the obligation to conduct a prior assessment of its effects on the environment, for the purposes of the SEA Directive. |

| 19 | According to that court, while the Decree of 1 December 2016 falls outside the scope of Article 3(2)(b) of the SEA Directive, the fact remains that such a measure could nevertheless constitute a plan or programme, within the meaning of either Article 3(2)(a) or Article 3(4) of the SEA Directive. |

| 20 | In those circumstances, the Conseil d’État (Council of State) decided to stay the proceedings and to refer the following questions to the Court for a preliminary ruling:





  ‘(1) | Is a decree by which a body of a Member State establishes the conservation objectives for the Natura 2000 network, in accordance with the [Habitats] Directive, a plan or programme within the meaning of the [SEA] Directive, and, more specifically, within the meaning of Article 3(2)(a) [of that directive] or of Article 3(4) of that directive? |

Consideration of the questions referred

Consideration of the questions referred

| 21 | By its questions, which it is appropriate to examine together, the referring court is asking, in essence, whether Article 3(2) and (4) of the SEA Directive must be interpreted as meaning that a decree, such as that at issue in the main proceedings, by which a body of a Member State establishes conservation objectives at regional level for its Natura 2000 network, is one of the ‘plans and programmes’ for which an environmental impact assessment is mandatory. |

| 24 | Lastly, given the objective of the SEA Directive, which is to provide for such a high level of protection of the environment, the provisions which delimit the scope of the directive, in particular those setting out the definitions of the measures envisaged by the directive, must be interpreted broadly (judgment of 27 October 2016, D’Oultremont and Others, C‐290/15, EU:C:2016:816, paragraph 40 and the case-law cited). |

It is in the light of those considerations that the questions referred must be answered.

| 27 | In that connection, first, the Belgian Government and Ireland argue that, in so far as the Decree of 1 December 2016 establishes conservation objectives, it could have only beneficial effects and, accordingly, would not require an environmental impact assessment. |

| 28 | It must, however, be borne in mind that, as regards Directive 85/337, the Court has already ruled that the fact that projects should have beneficial effects is not relevant in determining whether it is necessary to make those projects subject to an assessment of their environmental impact (judgment of 25 July 2008, Ecologistas en Acción-CODA, C‐142/07, EU:C:2008:445, paragraph 41). |

| 29 | Secondly, according to the Belgian Government and Ireland, on account of Article 3(2)(b) of the SEA Directive and the exception which applies to site management measures under Article 6(3) of the Habitats Directive, the strategic environmental assessment is restricted, so far as Natura 2000 sites are concerned, to the assessment of plans and projects which are also subject to an assessment of the implications for the site under the Habitats Directive. Following that analysis, measures for the management of those sites would never require an environmental assessment. |

Following that analysis, measures for the management of those sites would never require an environmental assessment.

| 30 | In the present case, it is clear from the order for reference that the Decree of 1 December 2016 is directly connected to the management of all sites in the Walloon region. It therefore does not concern a particular site, for the purposes of Article 6(3) of the Habitats Directive and, accordingly, nor does it require an environmental assessment pursuant to Article 3(2)(b) of the SEA Directive. |

It therefore does not concern a particular site, for the purposes of Article 6(3) of the Habitats Directive and, accordingly, nor does it require an environmental assessment pursuant to Article 3(2)(b) of the SEA Directive.

| 31 | That being said, the fact that a measure, such as that at issue in the main proceedings, need not be preceded by an environmental assessment on the basis of the combined provisions of Article 6(3) of the Habitats Directive and Article 3(2)(b) of the SEA Directive does not mean that it is exempt from any obligation in that regard, since it is not excluded that such a measure could enact rules which lead to it being placed on the same footing as a plan or programme for the purposes of the latter directive, in respect of which an environmental impact assessment may be mandatory. |

| 32 | In that connection, as the Advocate General states in points 64 and 65 of her Opinion, the fact that, in the context of the Habitats Directive, the EU legislature did not consider it necessary to adopt provisions on environmental assessment and public participation in connection with site management does not mean that it wished to exclude the management of Natura 2000 sites when it subsequently adopted general rules on environmental assessment. Assessments conducted under other environmental protection instruments co-exist and usefully supplement the rules of the Habitats Directive in relation to the assessment of potential environmental effects and public participation. |

| 33 | As regards, in the first place, the decree at issue in the main proceedings being placed on the same footing as a plan or programme for the purposes of the SEA Directive, it should be recalled that it follows from Article 2(a) of the SEA Directive that plans or programmes are those which satisfy two cumulative conditions, namely (i) having been subject to preparation and/or adoption by an authority at national, regional or local level or which are prepared by an authority for adoption, through a legislative procedure by Parliament or Government; and (ii) being required by legislative, regulatory or administrative provisions. |

| 34 | The Court has interpreted that provision as meaning that plans and programmes whose adoption is regulated by national legislative or regulatory provisions, which determine the competent authorities for adopting them and the procedure for preparing them, must be regarded as ‘required’ within the meaning, and for the application, of the SEA Directive and, accordingly, be subject to an assessment of their environmental effects in the circumstances which it lays down (judgments of 22 March 2012, Inter-Environnement Bruxelles and Others, C‐567/10, EU:C:2012:159, paragraph 31 and of 7 June 2018, Thybaut and Others, C‐160/17, EU:C:2018:401, paragraph 43). |

| 35 | In the present case, the Decree of 1 December 2016 was drafted and adopted by a regional authority, namely the Government of the Walloon Region, and that decree is required by Article 25a of the Law of 12 July 1973. |

| 36 | As regards, in the second place, the question of whether a plan or programme such as that at issue in the main proceedings must be preceded by an environmental assessment, it must be borne in mind that the plans and programmes which satisfy the requirements of Article 2(a) of the SEA Directive may be subject to an environmental assessment, provided that they are one of those categories referred to in Article 3 of the SEA Directive. Article 3(1) of the SEA Directive in fact provides that an environmental assessment is to be carried out for plans and programmes referred to in paragraphs 2 to 4 which are likely to have significant environmental effects. |

| 37 | Under Article 3(2)(a) of the SEA Directive, an environmental assessment is to be carried out for all plans and programmes which are prepared for agriculture, forestry, fisheries, energy, industry, transport, waste management, water management, telecommunications, tourism, town and country planning or land use and which set the framework for future development consent of projects listed in Annexes I and II to Directive 2011/92. |

| 38 | In that connection, the Belgian and Czech Governments, Ireland and the Commission have expressed doubts as to whether the establishment of conservation objectives for the Natura 2000 sites in a region of a Member State can fall within the scope of one of those sectors. |

| 39 | As the Advocate General notes in point 44 of her Opinion, in so far as, under Article 3(4) of the SEA Directive, Member States must determine whether plans and programmes, other than those referred to in Article 3(2), which set the framework for future development consent of other projects, are likely to have significant environmental effects, it must be determined whether a measure, such as that at issue in the main proceedings, sets such a framework. |

| 40 | As the Advocate General observes in point 69 of her Opinion, the obligation to carry out an environmental assessment, laid down in Article 3(4) of the SEA Directive, like the assessment requirement under Article 3(2)(a) of that directive, is dependent on whether the plan or programme in question sets the framework for future development consent of projects. |

| 41 | In that connection, the Court has ruled that the notion of ‘plans and programmes’ relates to any measure which establishes, by defining rules and procedures, a significant body of criteria and detailed rules for the grant and implementation of one or more projects likely to have significant effects on the environment (judgments of 27 October 2016, D’Oultremont and Others, C‐290/15, EU:C:2016:816, paragraph 49 and the case-law cited, and of 8 May 2019, Verdi Ambiente e Società (VAS) — Aps Onlus and Others, C‐305/18, EU:C:2019:384, paragraph 50 and the case-law cited). |

| 42 | In the present case, the Decree of 1 December 2016 does not set out conservation objectives for specific sites, but summarises them for the Walloon region as a whole. Furthermore, it is apparent from the third subparagraph of Article 25a(1) of the Law of 12 July 1973 that the conservation objectives at Walloon Region level have indicative value only, whereas the second subparagraph of Article 25a(2) provides that the conservation objectives applicable at the level of Natura 2000 sites have statutory value. |

| 43 | In the light of those factors, it must be held that a measure, such as that at issue in the main proceedings, fails to satisfy the condition recalled in paragraph 41 of the present judgment, in that it does not set a framework for future development consent of projects, with the effect that it does not come within the scope either of Article 3(2)(a) or Article 3(4) of the SEA Directive. |

| 44 | In the light of the foregoing, the answer to the questions referred is that Article 3(2) and (4) of the SEA Directive must be interpreted as meaning that a decree, such as that at issue in the main proceedings, by which a body of a Member State establishes, at regional level for its Natura 2000 network, conservation objectives which have an indicative value, whereas the conservation objectives at site level have a statutory value, is not one of the ‘plans and programmes’, within the meaning of that directive, for which an environmental impact assessment is mandatory. |
