The journey of Klimaatzaak

Supported by over 71,000 citizens, vzw Klimaatzaak (Climate Case) tackles the core of Belgium's climate problem: political stagnation. We are forcing our governments through the courts to take responsibility and lead society through the climate transition in a fair manner. Here you can read all about the progress of our court case.

Current situation

We have won at every stage of the proceedings. 

  • In 2021, the Court of First Instance ruled that the Belgian authorities had violated their duty of care by failing to adequately protect citizens their from climate hazards.
  • Because the judge did not impose any concrete measures, we appealed against our own victory.
  • Successfully: in 2023, the Court of Appeal imposed a binding reduction target of -55% by 2030.
  • The Flemish government lodged an appeal in the Court of Cassation (the Belgian Supreme Court) in 2024. 

We are now preparing to defend our case before the Court of Cassation and enforce implementation of the previous judgement through legal means, including penalty payments. All steps in the procedure can be found in this timeline, including the court rulings.

    Flanders lodges cassation appeal

    The Flemish government is the only government to lodge an appeal in cassation. The federal and Brussels governments are seizing this ruling to change course, following all scientific insights to make our country future-proof.
