The Intergenerational Effect of Fundamental Rights: A Contribution of the German Federal Constitutional Court to Climate Protection

By a recent judgment, the German Federal Constitutional Court enhanced the concept of fundamental rights to climate protection in three dimensions: their number, content and temporal reach. While previously fundamental rights to health, occupation and property have been trialled in domestic climate litigation, the Court here propounds almost all fundamental rights to being inflicted insofar as their enjoyment hinges upon the availability of fossil energy and thus the emission of greenhouse gases. Developing an intertemporal dimension of those rights, the Court finds an imbalance of permissible greenhouse gas emissions in that most of the emission budget available within a temperature increase of well below 2°C will be spent by 2030, leaving only a minimum use of fossil fuels for subsequent years and generations. This analysis summarises the Court’s legal reasoning, positioning it in the broader spectrum of fundamental rights doctrine, and reflects on the contribution of the case to the growing number of transnational climate jurisprudence.
