Summary:
On 30 November 2023, a Court of Appeal in Brussels, Belgium, issued its judgment in the Urgenda-inspired “Klimaatzaak” (Dutch for “climate case”). Its judgment builds on a 17 June 2021 first-instance judgment, which held that Belgian climate policy was negligent and violated positive obligations under the European Convention on Human Rights (Articles 2 and 8). While confirming this part of the judgment for three of the four domestic governments involved, the appeal court overturned the first instance’s finding that, in light of the separation of powers, it could not set greenhouse gas reduction targets. The appeal court set clear targets for domestic emissions reductions, ordering reductions of 55 percent by 2030 (compared to 1990 levels).
First-instance judgment:
The applicants in this case alleged, among other things, that the four Belgian governments (i.e. the three regional governments and the federal state) had violated human rights law, and were obligated to reduce Belgium’s greenhouse gas emissions by 40% by 2020 compared to 1990 levels.
The case was delayed for almost three years because of proceedings contesting the language of the case, which was ultimately adjudicated in French.
On 17 June 2021, a court of first instance found that Belgian climate policy was negligent and violated positive obligations under human rights law. At stake were, among other things, violations of Articles 2 and 8 ECHR, in claims inspired by the Dutch Urgenda case. However, the court of first instance also held that, in light of the principle of separation of powers, it could not set greenhouse gas reduction targets for the Belgian governments.
The Brussels court of first instance not only declared the complaint of the applicant association, VZW Klimaatzaak, admissible, but also that of the 58,000 co-plaintiffs. Belgian law does not allow for an actio popularis, but the first-instance court recognized that all of the applicants faced a risk of material, physical or moral damage. In doing so, it referred to the risks to human and animal health and to the territorial integrity of the Belgian state, and especially of the Flemish region, which was particularly at risk of harms caused by sea level rises. The best available science, as reflected in existing diplomatic consensus, did not leave room for doubt about the existence of a real risk from dangerous climate change. This meant a serious risk that current and future generations would see their daily lives profoundly impacted (“profondément perturbées”). The fact that other Belgian citizens could bring a similar claim did not change this.
The judgment also stated that the federal state and the three regions are jointly and individually responsible for the risk of harm at stake, despite the complex structure of the Belgian state.
Lastly, the judgment stated that the four governments’ inadequate climate policy violated articles 2 and 8 of the European Convention on Human Rights (ECHR) (which enshrine the right to life and the right to respect for private and family life, respectively).
However, the court did not order the injunction claimed by the applicants for concrete reduction targets. The applicants had requested an injunction to the effect that the Belgian state should reduce greenhouse gas emissions by 42% by 2025 and by 55% by 2030.
Judgment on appeal:
On appeal by the applicants, who challenged the first-instance judgment over the decision not to order concrete reductions targets, the case was reviewed by the Brussels Court of Appeal. Its judgment, which was issued on 30 November 2023, confirmed that the 2020 climate policy of three out of the four respondent domestic governments had violated Articles 2 and 8 ECHR. In its judgment, the court ordered the Belgian state, the Flemish Region and the Brussels-Capital Region to reduce their greenhouse gas emissions more quickly, namely by 55 percent by 2030 (compared to 1990 levels). Meanwhile, it found that the Walloon region’s climate policy had progressed sufficiently to be in conformity with human rights law.
In its judgment, the court found that “in light of the prevailing consensus within the scientific community and the international political community, the three governments have violated Articles 2 and 8 of the European Convention on Human Rights (ECHR) and Articles 1382 and 1383 of the old Civil Code because they had not sufficiently reduced greenhouse gas emissions in 2020” (our translation). This violation was still ongoing because these governments have “set insufficiently strict targets and have not taken sufficiently far-reaching measures to sufficiently limit emissions by 2030”. The court found that “a reduction of -55% in GHG emissions by 2030 constitutes a minimum threshold, below which Belgium cannot go under penalty of violating Article 2 of the ECHR” (in the original French: une diminution de -55 % des émissions de GES à l’horizon 2030 constitue ce seuil minimal, en deçà duquel la Belgique ne peut aller sous peine de ne pas respecter l’article 2 de la CEDH). In doing so, it draws on the European Climate Law, which codifies the goals set out in the European Green Deal for the EU to become climate-neutral by 2050.
While the applicants had requested a penalty payment of 1 million euros per month, the appeal court deferred its ruling on this issue to await, among other things, emissions figures from the 2022-2024 period.
Status of case:
After the November 2023 ruling, further proceedings — in cassation, and potentially before the European Court of Human Rights — are possible in this case, which is accordingly not yet final.
