On June 5, 2021, environmental justice NGO A Sud and more than 200 plaintiffs filed suit alleging that the Italian government, by failing to take actions necessary to meet Paris Agreement temperature targets, is violating fundamental rights, including the right to a stable and safe climate. The action, part of a campaign called Giudizio Universale (The Last Judgment), seeks a declaration that the government's inaction is contributing to the climate emergency and a court order to reduce emissions 92% by 2030 compared to 1990 levels. According to an executive summary of the claim released by the plaintiffs, the government's climate obligations stem from the Paris Agreement, EU regulations, and IPCC reports. The human right to a stable and safe climate is based on guarantees in Article 6 of the Treaty of the European Union (guarantee of fundamental rights), and Articles 2 (right to life) and 8 (right to privacy) of the European Convention on Human Rights, among others. These rights violations give rise to non-contractual liability of the Italian government under Article 2043 of the Italian Civil Code. 

On December 14, 2021, the first hearing was held before the Civil Court of Rome in the form of written notes. In its reply, the Presidency of the Council of Ministers, represented by the “Avvocatura Generale dello Stato” (state lawyers), requested the Court to declare the complaint inadmissible and, in any case, to dismiss the applicants’ claims on the merits. On the matter of fact, the reply describes in depth the State’s policies and endeavors on climate change. On the matter of law, the reply deals with: (i) the absence of jurisdiction of the civil judge over activities pertaining to the legislative and executive powers of the State; (ii) the lack of standing rights of the applicants; (iii) the impossibility of placing an individual responsibility on the Italian State for climate change and its impact. 


The applicants sent their rebuttal notes on January 14, 2022. The second hearing (the first oral hearing) has been held on 21 June 2022. The parties presented their legal arguments before the judge. The judge scheduled the next hearing for September 13, 2023.

Following the final hearing on 13 September 2023, the Judge of the Second Civil Section of the Court of Rome requested the parties' closing statements and proceeded with the ruling.

In its judgment of February 26, 2024, the Court declared the claims inadmissible for absolute lack of jurisdiction (‘difetto assoluto di giurisdizione’). 

The Court applied the principle of separation of powers and the related case law. The Court pointed out that the claim entails a review of the sphere of powers that the Constitution reserves to the legislature. 

In the Court's opinion, "the interest for which compensation is claimed under Articles 2043 and 2051 of the Italian Civil Code does not fall within the category of legally protected subjective interests, since decisions relating to the methods and timescales for managing the phenomenon of anthropogenic climate change - which involve discretionary socio-economic assessments and in terms of cost-benefit in the various sectors of human life - fall within the sphere of attribution of the political bodies and cannot be sanctioned in the present proceedings. With the proposed civil action, the plaintiffs essentially ask the Court to annul the measures, including primary and secondary regulatory measures (...) that constitute the implementation of the political choices of the legislature and the government for the achievement of the objectives assumed at international and European level (in the short and long term) in violation of a cardinal principle of the order represented by the principle of separation of powers" (unofficial English translation, p. 12 of the judgment).  

A Sud appealed the court ruling, but a new ruling will not be made until October 21, 2026.

An aim to achieve a quantifiable outcome within a given time-frame, set by an institution such as a national government.

Policy instruments are techniques or tools used by governing authorities to promote certain policies in order to achieve predetermined goals. Put simply, instruments are how a government tries to achieve its goals, with this taxonomy being focused on national policy instruments.

Risk is the potential for adverse consequences resulting from the dynamic interplay between (climate-related) hazards, exposure, and vulnerability of affected human or ecological systems.

Climate change can have a range of impacts on technological system. Extreme weather events can cause infrastructure failures like power outages or damage to roads and bridges, as well as the impacts from waste following natural disasters. Human activities also cause technological impacts, such as the risks posed by oil spillage and leaks.

Climate change impacts our society by disrupting the natural, economic and social systems we depend on. Physical hazards and underlying vulnerabilities can lead to increased resource competition for food and water, which can heighten the risk of conflict.

Slow onset events evolve gradually from incremental changes over many years or from increased frequency or intensity of recurring events. As defined in the Cancun Adaptation Framework (2010), slow onset events include risks and impacts from rising temperatures, desertification, biodiversity loss, land and forest degradation, glacial retreat, ocean acidification, sea level rise, and salinization.

Heavy precipitation refers to any form of weather where substances fall from the sky, including rain, snow, sleet, or hail.

The cryosphere is the frozen part of the Earth—it includes sea ice, glaciers, snow, and ice sheets. It helps regulate the climate and weather by reflecting sunlight. Rising temperatures are causing melting, leading to sea ice loss, glacier collapse, and glacier landslides and avalanches. This threatens the livelihoods of around 700 million people who rely on the cryosphere for food, water security, and cultural practices.

Geohazards are adverse geological phenomenon's that are capable of causing widespread damage or loss to property, life and the environment, such as earthquakes, volcano eruptions and tsunamis.
