(de-news.net) – As federal and state politicians debate whether climate protection and adaptation should receive greater constitutional status, Germany’s climate policy is coming under renewed pressure for action. The discussion reflects a broader question facing the government: how to strengthen climate resilience and continue reducing emissions while confronting a fragile economic situation.
Andreas Jung, deputy chairman of the Christian Democratic Union (CDU) and a leading party voice on climate policy, argued that although substantial progress had already been made, further measures remained necessary. In his view, economic conditions and climate policy could not be considered separately.
Jung maintained that an amendment to the Basic Law was not necessary to finance climate-related investment by municipalities. At the same time, he pointed to increasingly urgent adaptation needs in schools, daycare facilities and other public buildings, where temperatures of 30 to 35 degrees Celsius or higher have underscored the practical consequences of extreme heat. Such facilities, he argued, need to be made both energy-efficient and more resilient to heat. Because financially strained municipalities would struggle to manage those investments on their own, climate adaptation should instead be treated as a shared responsibility involving municipalities, the states and the federal government.
For Jung, the central challenge for Chancellor Friedrich Merz is to reconcile climate protection with economic recovery rather than treating them as competing priorities. If climate policy is pursued through technological innovation, he argued, it could become an economic model that creates opportunities for international cooperation and exports. Germany’s contribution could consequently extend beyond the country’s comparatively small share of global carbon dioxide emissions by enabling technologies developed domestically to be adopted elsewhere.
Jung also pointed to a precedent for acting without changing the constitutional framework. An energy-efficiency program for municipalities introduced during the 2009 economic crisis, he noted, had operated under the existing Basic Law and proved effective. Comparable measures, he argued, could therefore be introduced immediately, drawing on money from special funds as well as revenues generated through carbon pricing. Investment in public buildings would serve more than one purpose, in his assessment, by improving their climate performance while also making them better able to withstand periods of extreme heat.
The Climate Union, an association of CDU and Christian Social Union (CSU) members that supports climate policy aligned with the 1.5-degree target, has likewise called on the chancellor to make climate protection a priority ahead of the federal cabinet’s retreat in Neuhardenberg. Thomas Heilmann, the group’s chairman and a former CDU member of the Bundestag, argued that Germany should remain on its existing climate policy course while simultaneously strengthening its capacity to cope with heat, drought and other forms of extreme weather. The two strands of policy, he maintained, should be pursued together because earlier action could save lives, protect prosperity and reduce the financial costs associated with more severe climate impacts later.
Heilmann has also opposed establishing a new constitutional framework for climate adaptation. In his assessment, the federalism reforms of 2009 had deliberately clarified the responsibilities of the federal government, states and municipalities, while a constitutional amendment would not itself provide additional funding. He instead advocated using existing revenues from emissions trading for the climate-related purposes for which they were intended. Heilmann, who has headed the Climate Union since 2022 and represented Berlin’s Steglitz-Zehlendorf district in the Bundestag from 2017 to 2025, has at the same time pressed the federal government to intensify measures aimed at climate adaptation and heat protection.
State-level CDU opposition grows over climate amendment
Opposition to the proposed constitutional amendment has also emerged among CDU environmental ministers at the state level. Georg-Ludwig von Breitenbuch, Saxony’s environment minister, argued that the Basic Law should not be burdened with additional provisions when effective adaptation measures could already be implemented within the existing legal framework. He specifically opposed making heat protection a constitutional state objective. Von Breitenbuch also criticized Federal Environment Minister Carsten Schneider for advancing the proposal beyond the coalition agreement’s mandate to examine the issue, arguing that the move was inconsistent with cooperative relations between the federal government and the states.
Christine Schneider, Rhineland-Palatinate’s agriculture and environment minister, likewise called for any constitutional amendment to be assessed carefully against the legal and financial alternatives already available. In particular, she emphasized the importance of speeding up approval procedures, as envisaged by the federal government’s planned infrastructure legislation. Constitutional recognition of climate adaptation, she argued, would not by itself alter the broader social responsibility for addressing the issue.
Hesse took a less explicitly oppositional position. The state said it would participate constructively in federal-state discussions on climate adaptation and possible joint approaches, while emphasizing that the decisive factor was the implementation of concrete and effective measures at the local level. Its position thus stopped short of directly rejecting the proposal while maintaining the focus on practical action.
The federal cabinet was scheduled to take up Schneider’s proposal beginning Tuesday during its retreat in Neuhardenberg. Changing the Basic Law would require two-thirds majorities in both the Bundestag and the Bundesrat, making support across Germany’s federal political system essential. The initiative has received backing from Social Democratic Party (SPD) ministers, including Vice Chancellor Lars Klingbeil, adding a further dimension to the debate within the governing coalition.
The political dispute comes as climate indicators continue to point to mounting environmental pressure. The global average sea-surface temperature reached a record daily high of 21.1 degrees Celsius on Aug. 22, surpassing the previous record of 21.09 degrees set in March 2024, according to the European Union’s Copernicus Climate Change Service. The record adds urgency to a debate that increasingly concerns not only long-term emissions reductions but also the ability of communities and public infrastructure to withstand immediate climate-related stresses.
Copernicus has warned that warmer oceans can increase the potential for extreme weather because they transfer greater amounts of heat and moisture into the atmosphere. That additional energy and moisture can contribute to more intense rainfall and storm systems, increasing the potential severity of extreme-weather events. Rising sea temperatures can also reduce the ocean’s ability to absorb carbon dioxide, potentially weakening an important natural buffer against climate change.
Samantha Burgess, a climate expert at the European Center for Medium-Range Weather Forecasts, has attributed part of the current warming to the El Niño phenomenon. But she also emphasized the broader context in which that temporary influence is occurring: decades of global warming driven by human activity. The distinction underscores the wider challenge confronting policymakers, as short-term natural climate variability is superimposed on a longer-term warming trend that continues to shape the debate over both climate protection and adaptation.
