Neubauer v. Germany was a 2020 court case in which a group of activists sued over the vagueness present in 2019's Climate Protection Act.
Activists backed by Fridays For Future, Greenpeace, Friends of the Earth, and other NGOs brought claim that the lack of a comprehensive legal framework to reduce carbon emissions by 2030 violated their fundamental rights as enshrined in German basic law.
[2] The Constitutional Court declared part of the Federal Climate Protection Act unconstitutional, as it did not "sufficiently protect people against future infringements and limitations of freedom rights in the wake of gradually intensifying climate change".
[3] It ruled against some of their claims, saying the plaintiffs could not prove the government violated its constitutional duty.
The finance minister responded to the ruling by saying that he would work with the environment ministry to amend the act.
