Rhine drought, heatwaves and deaths: Is it time for Germany to enshrine climate protection in law?

Germany’s coalition government is split over putting climate protection in the constitution. A debate is heating up in Germany over whether to enshrine climate protection in the constitution. The proposal by a group of German ministers sparked pushback from within the government on 17 August, despite Western Europe sweltering through record-breaking summer temperatures – with a litany of ill effects. Germany alone has recorded around 12,500 heat-related deaths in 2026 so far. The country has also temporarily relaxed truck-driving restrictions to ease pressure on supply chains disrupted by record-low water levels on the Rhine. Climate scientists say global warming is intensifying drought and wildfires, dropping river levels and threatening harvests in Europe's biggest economy. German ministers say law limits response to climate crisis Ministers from the centre-left Social Democrats (SPD), junior coalition partners to Chancellor Friedrich Merz's conservatives, said Berlin must enshrine the need for "climate adaptation and nature conservation" in the German constitution, known as the Basic Law. They urged changes to urban planning legislation and building codes, and new labour laws to address working in high temperatures. With the Rhine running low and forest fires flaring, the SPD's Environmental Minister Carsten Schneider said the climate crisis was now a "tangible reality" but that current law limits what his ministry can do in response. Key figures in Merz's CDU/CSU bloc were however lukewarm on the idea, warning about the potential costs. Klaus Mack, deputy chairman of the CDU's parliamentary group, raised concerns about possible fiscal implications and administrative hurdles. The CDU's climate policy spokesman, Mark Helfrich, told Politico that they "are not convinced" by the SPD idea of new joint funding for national, regional and local climate measures. Who supports a German climate protection law? Environmental groups largely voiced support for the SPD proposal and criticised Merz for not laying out a plan of his own about how to address drought, heat and water shortages. "This summer of extremes shows that Germany is ill-prepared for the heatwaves striking us with increasing frequency due to the escalating climate crisis," Barbara Metz, head of Environmental Action Germany (DUH), told the RND media group. The opposition Greens in principle also back the idea – but their party chief Felix Banaszak charged that the SPD had previously blocked similar proposals and warned voters: "Don't fall for these con artists." Climate action "is not rocket science", he added, demanding more renewable energy and grid and storage capacity to make Germany "independent of fossil fuel imports". Is Germany backsliding on climate commitments? Merz has faced accusations of backsliding on Germany's robust climate commitments, as he has sought to bolster the economy by cutting red tape and bringing down energy costs. An expert commission in May forecast that Germany would miss its 2030 greenhouse gas emissions targets, which are anchored in law. DUH – which successfully sued the previous government over a climate plan that courts determined was inadequate – has also brought a lawsuit over the current government's climate action plan. The SPD plan would require support from Merz's conservatives, as amending the Basic Law requires a two-thirds majority in parliament. The far-left Die Linke party dismissed the proposal as "empty promises" while the far-right and climate-sceptic AfD categorically rejected it. Other European countries are debating similar reforms. In Spain, Prime Minister Pedro Sanchez's leftist government in June unveiled a programme to strengthen "resilience to heatwaves, floods, droughts and other risks posed by climate change". It calls for sweeping measures such as a national network of climate shelters and more urban greenery, but it is not clear whether it can get the necessary consensus and money to implement it.
