Children and young people Domestic court Emissions reductions/mitigation Germany Paris Agreement Right to a healthy environment Self-determination

Marlene Lemme et al. v. Bayern

This case is one of ten separate constitutional complaints and one subsidiary popular complaint supported by the NGO Deutsche Umwelthilfe against ten German States (“Bundesländer”). It was brought by ten youth plaintiffs concerning the codification of the adjusted climate goals brought about in response to the Neubauer v. Germany judgment of the German Bundesverfassungsgericht. According to the applicants, in their constitutional claim, the German States (“Bundesländer”) share responsibility for protecting their lives and civil liberties, along with those of future generations, within their spheres of competence. They argue that the lack of legislation on climate action on the state level violates the German Constitution and the reductions regime under the Paris Agreement, and that they have a fundamental right to defend themselvse against future rights impacts caused by the lack of climate measures.

The Bavarian Climate Protection Act (Bayerisches Klimaschutzgesetz) aims to reduce greenhouse gas emissions by 55% compared to 1990 levels by 2030. It also aims to achieve net zero emissions by 2050, and requires Bavaria to offset emissions after 2030. This has been implemented through a climate protection program. According to the plaintiffs, the lack of a deadline of adaptation strategy, and the failure to provide differentiated targets or instruments for implementation of compliance, mean that the Bavarian law falls short of the Federal requirements on climate protection measures.

On 18 January 2022, the First Senate of the Federal Constitutional Court dismissed all eleven complaints for lack of adequate prospects of success. In alignment with its argumentation in Neubauer v. Germany, the First Senate recognized that the burden of CO2 emissions reductions must not be unilaterally offloaded onto future generations. However, the First Senate stated the individual legislators of the Bundesländer have not been been given an overall reduction target to comply with, even at the expense of freedom protected by fundamental rights. Thus, according to the First Senate’s decision, a violation of the obligations to protect the complainants from the dangers of climate change cannot be established. As regards to the Bundesländer, the First Senate clarified that they still have a responsibility to protect the climate, particularly by virtue of Article 20a of the German Constitution.

Rights invoked:
The applicants invoked violations of various freedoms guaranteed under the domestic Constitution, especially those in Art. 2(1) of the German Constitution (right to free development of one’s personality), in combination with Article 20a of the Constitution (protection of the natural foundations of life and of animals). They invoked these rights in their ‘intertemporal dimension’, i.e. taking on the framing of the Neubauer case, which considered that failure to act now on climate change means excessively impacting future freedoms.

Date of decision:
18 January 2022

Related proceedings:
In addition to the constitutional proceedings, a subsidiary popular complaint has been brought by the same group of applicants to contend that the Bavarian Climate Protection Act (Bayerisches Klimaschutzgesetz), along with the wider regulatory context, is in violation of constitutional rights.
