The case, explained

PNRR Funding Revocation and Violation of the DNSH Environmental Clause

6 min read · Updated August 2026 · Editorial oversight: Avv. Federico Papa

Developments in the first months of 2024 mark a critical turning point for PNRR management in Italy. According to press reports, the Ministry of Economy and Finance has formalised a widespread series of funding revocation orders against numerous local authorities due to non-compliance with European environmental parameters. This analysis explores the civil and administrative implications of the DNSH clause, distinguishing it from the criminal aspects discussed in dedicated articles within this column, to focus on its nature as an essential condition for the validity of public tenders. The case highlights the tension between the need for swift expenditure and the rigor of sustainability criteria imposed by Brussels. Through our usual twin case, we will see how the omission of a single technical sheet can disrupt the entire economic planning of a local authority.

In brief

The article examines the recent wave of PNRR funding revocations (early 2024) resulting from the violation of the DNSH (Do No Significant Harm) principle. Unlike criminal fraud profiles, the analysis focuses on the nature of DNSH as a mandatory rule that automatically integrates tender notices. Through the reconstruction of the Venice and Florence cases and the Court of Auditors' monitoring, it illustrates how the absence of environmental technical documentation leads to the nullity of procedures and the definitive loss of EU contributions.

  1. The facts

    According to reports by Italia Oggi and Enti Locali & Edilizia del Sole 24 Ore, the audit phase concluded in early 2024 confirmed the definitive blocking of funding for several major metropolitan works. The case stems from findings by the European Commission and the Court of Auditors, which as early as the 2024 Report had signaled serious criticalities in Integrated Urban Plans, explicitly citing cases like the Bosco dello Sport in Venice and the stadium renovation in Florence. The current procedural stage is mainly administrative and accounting: after the denial of PNRR funds by the Ministry of Economy, the affected municipalities appealed the revocation orders before the Regional Administrative Court (TAR). Simultaneously, the accounting judiciary has initiated investigations to evaluate the hypothesis of accounting damage against executives, resulting from the alleged loss of EU contributions due to presumed negligence in preparing tender documents. At the heart of the dispute is the failure to include the so-called DNSH technical sheets in the tenders, which guarantee that the work does not cause significant harm to the environment.

  2. The rules in play

    1. Regulation (EU) 2020/852 (Taxonomy) defines the concept of significant harm to environmental objectives in Art. 17, establishing criteria for considering an activity eco-sustainable.
    2. Regulation (EU) 2021/241 establishes the Recovery and Resilience Facility, imposing DNSH compliance as an eligibility condition for each funding installment.
    3. Decree-Law 77/2021 (PNRR Governance) provides in Art. 8 for the automatic revocation of funds if the irregularity committed by the implementing body prejudices reporting to the European Union.
    4. Legislative Decree 36/2023 (Public Procurement Code) states in Art. 57 that PNRR environmental clauses constitute essential contract requirements, the absence of which can lead to the nullity of the award.

  3. What the case law says

    Administrative jurisprudence has recently consolidated a rigorous position, qualifying the DNSH principle as a mandatory rule of economic public order. According to the judges of Palazzo Spada, the environmental requirements of the PNRR operate through the mechanism of automatic integration of the tender notice: even if the municipality omits them, they are considered an integral part of the contract. However, the lack of documentary evidence of compliance with these parameters in the technical offer justifies the immediate exclusion of the bidder. The accounting magistrates, for their part, have clarified that the loss of public funding due to non-compliance with clear technical clauses does not fall within the lawful risk covered by the Business Judgment Rule, but constitutes gross negligence. The principle of proportionality of revocation, often invoked by municipalities, is applied with extreme caution, as the European Commission does not allow partial derogations regarding investment sustainability.

  8. What it teaches professionals

    1. Monitoring oversight: one must constantly verify the consistency between the executive project and the DNSH mappings uploaded to the ReGiS system.
    2. Tender drafting: lawyers must insert indemnity clauses and specific documentary obligations for the contractor regarding EU parameters.
    3. Management of variations: any modification during construction must be previously assessed for environmental impact to avoid expenditure decertification.

Frequently asked questions

What happens if a Municipality loses PNRR funds for environmental reasons?

The entity must return the advanced sums and, if the work has already started, must find alternative coverage in its own budget or rely on national refinancing, exposing administrators to accounting liability.

Is it possible to cure the lack of DNSH documentation after the award?

Procedural cure is strictly limited; case law tends to deny it if compliance with the DNSH principle required specific design choices or materials that should have been declared at the time of the offer.

Who is liable for the damage if the tender was poorly written?

Liability usually falls on the Single Project Manager (RUP) and the executives who signed the acts, unless it is proven that the error resulted from contradictory ministerial instructions.
