Similar to the Urgenda case in the Netherlands, the Klimaatzaak -- "climate case" -- was brought by an organization of concerned citizens, and 58,000 citizen co-plaintiffs, arguing that Belgian law requires the Belgian government's approach to reducing greenhouse gas emissions to be more aggressive. The suit named the Belgian State, the Walloon Region, the Flemish Region, and the Brussels-Capital Region as defendants. Specifically, plaintiffs called for reductions of 40% below 1990 levels by 2020 and 87.5% below 1990 levels by 2050.

From February 2019 through March 2020, the parties submitted their main conclusions and final conclusions. In their main conclusions, the plaintiffs seek a Court injunction directing the government to reduce emissions 42 to 48% in 2025 and at least 55 to 65% in 2030. Oral arguments were heard from March 16 to 26, 2021. 

On June 17, 2021, the Brussels Court of First Instance held that the Belgium government breached its duty of care by failing to take necessary measures to prevent the harmful effects of climate change, but declined to set specific reduction targets on separation of powers grounds. 

The Court first analyzed whether the claim was admissible, and, in doing so, whether the plaintiffs established that the proceedings would provide a benefit to them. Article 17 of the Judicial Code excludes actions brought in the general interest that only indirectly benefit the plaintiff. The Court found that both the 58,000 co-plaintiffs and the Klimaatzaak organization have a personal interest in the action. The citizen co-plaintiffs have a direct, personal interest because they seek to hold Belgian authorities responsible for the climate consequences on their daily lives, and the fact that other Belgian citizens may also suffer damages does not transform their interest into a general one. The Klimaatzaak organization has a direct, personal interest in part because environmental organizations have a privileged status to sue to defend the environmental from harm.

The Court found the federal state and the three regions jointly and individually in breach of their duty of care for failing to enact good climate governance. The Court found that despite being aware of the certain risk of dangerous climate change to the country's population, the authorities failed to take necessary action, meaning that they failed to act with prudence and diligence under Article 1382 of the Civil Code. Further, by failing to take sufficient climate action to protect the life and privacy of the plaintiffs, the defendants were in breach of their obligations under Articles 2 and 8 of the European Convention on Human Rights.

However, the Court declined to issue an injunction ordering the government to set the specific emission reduction targets requested by the plaintiffs. The Court found that the separation of powers doctrine limited the Court's ability to set such targets, and doing so would contravene legislative or administrative authority. Neither European nor international law required the specific reduction targets requested by the plaintiffs, and that the scientific report that they relied on, while scientifically meritorious, was not legally binding. The specific targets, therefore, were a matter for the legislative and executive bodies to decide. 

On November 17, 2021, Klimaatzaak appealed the judgment of the Brussels Court of First Instance. The appeal is primarily aimed at the Tribunal's refusal to set specific binding targets related to the reduction of greenhouse gas emissions over time. Klimaatzaak notably argues that the Brussels Court of First Instance has confused two distinct sources of liability in its analysis of Article 1382 of the Belgian Civil Code in that it confined itself to taking as a reference only the emission reduction targets laid down by rules of positive international, European and Belgian law, and refrained from analyzing the authorities' conduct in the light of their knowledge of the danger and of what needed to be done to help prevent or limit it. Klimaatzaak also asks the Court of Appeal to repeal and correct what they argue are factual or legal errors in the judgment of June 17, 2021. The defending Governments are expected to reply to this petition and the Brussels Court of Appeal will review the factual and the legal components of the case in the course of the appeal procedure.

After a written round of conclusions that will take sixteen months, the case was heard from September 14 to October 6, 2023.

The Court of Appeal of Brussels handed down its decision on November 30, 2023. The Court confirmed the finding of breaches established at first instance (except in the case of the Walloon Region), but in addition, ordered the condemned authorities to reduce their GHG emissions. Unlike the judge at first instance, the Court therefore considers that using its power of injunction against public authorities does not necessarily infringe the principle of separation of powers, provided that the judge does not take the place of the authorities in choosing the means to remedy violations. Competent Belgian public authorities (the Federal State, Flemish Region and the Brussels-Capital Region) have been ordered to reduce their GHG emissions of 55% compared to the 1990 level by 2030. The grounds of this decision are based on the breach of human rights (articles 2 and 8 of the ECHR) and civil liability rules (articles 1382 and 1383 of the (Former) Civil Code). 

However, the Court reformed the first instance judgment towards the Walloon Region by establishing that this authority is already playing its role in the fight against climate change. Therefore, the Court observes that there is no breach of human rights or civil liability rules on the part of the Walloon Region. The Court suspended its ruling on the question of the penalty payment and the production of the GHG emissions reports, depending on the official figures to be produced for the period 2020-2024 by the convicted authorities. The parties have 3 months to lodge a final recourse with the Court of Cassation.

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.

The processes through which enterprises can identify, prevent, mitigate and account for how they address their actual and potential adverse impacts. Due diligence is the idea that reasonable precautions should be taken to avoid causing harm to people, the environment, or society.

Terrestrial means "of the earth" and relates to the risks to ecological system that includes all living organisms and their interactions within land-based environments, such as forests, grasslands, and deserts.

Air pollution involves harmful contaminants in the air, affecting both indoor and outdoor environments. It can lead to health issues like respiratory diseases and heart problems, and climate impacts such as global warming. Pollutants can damage plants, trees, habitats, and water bodies like rivers and lakes.

Social inclusion is the process of improving the terms on which individuals and groups take part in society—improving the ability, opportunity, and dignity of those disadvantaged on the basis of their identity.

Fossil gas, commonly known as natural gas, is a fossil fuel consisting chiefly of methane with smaller amounts of other hydrocarbons and trace gases, found in underground deposits.

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.

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. Climate change can increase the frequency and severity of some geohazards, such as landslides, and soil erosion.
