In mid-September 2026, an alliance of over 130 Swiss organizations, including scientific groups and labor unions, mobilized for nationwide peaceful protests. Operating under the motto ‘Keine 50-Grad-Sommer!’ (No 50-Degree Summers!), the movement targeted the federal government, the financial sector, and multinational corporations to demand systemic economic and social transformations to reduce greenhouse gas emissions.

Protesters specifically highlighted the disproportionate role of Switzerland’s financial and commodity sectors in the climate crisis, as well as the immediate health risks posed by extreme heat to workers. For instance, the Unia union noted that many construction workers were denied recommended cooling breaks during high temperatures. In Basel, activists such as 19-year-old Marlene Boje have emphasized the necessity of fighting for every 0.1 degree of temperature reduction. The movement has expanded to include diverse groups such as families, teachers, and forestry professionals.

Following the initial call for mobilization, thousands of demonstrators gathered in cities such as Geneva and Lausanne. In Lausanne, police estimated approximately 12,000 participants, while in Geneva, organizers reported around 7,000 people, though police figures cited 3,000. Speakers at the rallies included representatives from the agricultural and education sectors, as well as Green Party President Lisa Mazzone, who criticized right-wing politicians for denying the climate emergency.

Activists sought to pressure political parties into implementing urgent environmental protections to prevent extreme temperatures from reaching 50 degrees Celsius by 2050. Demonstrators specifically targeted federal authorities, including Federal Councillor Albert Rösti, demanding urgent CO2 reduction and adaptation measures to prevent heatwaves and water shortages. These demonstrations occurred in the context of a 2024 European Court of Human Rights ruling that condemned Switzerland for failing to take adequate climate action.
