Who is Lisa Mazzone and what role does she play in the Greens?

Lisa Mazzone is the president of the Swiss Green Party. Originally from Geneva, she leads the party in carrying out criticism of the federal management of climate change, especially with regard to the decisions of the Federal Council and the allocation of public resources between defense and environmental protection. His interview before party delegates in Freiburg represents the official position of the Greens on federal climate policy.

What does DATEC mean in the context of Mazzone's request?

DATEC is the acronym for the Department of Environment, Transport, Energy and Communications. Albert Rösti heads this federal department. Mazzone asks that the Federal Council remove him from this post because he is not ensuring sufficient priority to climate protection within a department with very transversal competences, where the climate is subordinated to short-term pressures from transport and energy.

How much has the Federal Climate Council allocated to defence?

According to Mazzone, the Federal Council has allocated an additional 900 million francs to the army. In the same budgetary context, the government has not allocated even one additional franc for climate protection and climate adaptation. This direct contrast highlights the federal priority scale: defense before climate.

How does the lack of federal investment in the climate impact Swiss residents?

Without specific federal investments, municipalities and cantons must locally finance climate adaptation measures (energy isolation, urban greening, resilient water supply), increasing the local tax burden. Farmers, workers and consumers face rising costs related to extreme heat, droughts and food price volatility. Quality of life and productivity are directly impacted by heat waves.

What has the Federal Council decided about the Sustainable Financial Square initiative?

The Federal Council rejected the initiative on the sustainable financial square. According to Mazzone, this initiative could have had a significant impact on the global climate, directing international financial flows towards climate-sustainable investments. The refusal represents, for the Greens, a further sign of immobility and absence of climate ambition on the part of the federal government.

In brief

Lisa Mazzone calls on Federal Council to change course on climate
Government spent CHF 900M on defense, zero on climate protection
Greens: Remove DETEC from Rösti, prioritize climate and renewables

Key facts

Who: Lisa Mazzone, president of the Greens
What: Criticizes Federal Council's inaction on climate change
When: During the party delegates' assembly (summer 2026)
Where: Fribourg, Greens Party delegates meeting
Amount: CHF 900 million extra for army vs. zero for climate
Federal decision: Rejected initiative on sustainable financial center

Lisa Mazzone, president of the Greens, issued a stark warning at the party delegates' assembly in Fribourg. The central theme of her speech? The Federal Council's inaction in the face of the heatwaves of the past summer, which left gaps in decisions and concrete measures for Switzerland's climate.

'The Federal Council must remove the environment department from Albert Rösti,' stated the Geneva native, addressing the federal government directly. According to the Greens' president, the Swiss executive has clear responsibilities and must 'change course' in a radical and immediate way.

The demand is broad and incisive. Mazzone stressed that the Federal Council must 'put climate first,' 'adopt urgent measures to adapt our cities and countryside,' and 'invest heavily in climate protection by ending the harmful dependence on fossil fuels.' Words that summarize a vision of profound transformation of federal policy.

The Federal Climate Debate and the Role of DETEC

The challenge that Mazzone raises goes beyond a simple ministerial reorganization: it touches the heart of Swiss federal governance and how Bern intends to address the climate crisis in the coming years in a structural way.

Albert Rösti, director of the DETEC (Department of the Environment, Transport, Energy and Communications), has been a point of friction in the Swiss political debate for months. Attributing the climate dossier to a department that also manages transport, energy and communications creates priority conflicts: how to balance road expansion, rail efficiency, digital infrastructure and renewable investment with the imperative to reduce emissions and protect the climate?

The Greens' position suggests that the current institutional set-up is not sufficient to ensure coherent and truly priority climate protection. If the climate is managed within a cross-cutting department, it risks being subordinated to short-term pressures from other sectors.

Federal investments and pressure on Swiss municipalities

Without climate-specific federal investments, Swiss municipalities and cantons must locally finance climate adaptation measures. Thermal insulation of public buildings, urban greenery to reduce heat islands, public cooling systems, resilient water supply: all

Key points

### What these choices mean for those who live and work in Switzerland Heatwaves and droughts are not political abstractions confined to international climate conferences: they directly impact rents, food prices, energy costs, drinking water availability, quality of life, and productivity in every Swiss canton. If the Federal Council continues to fail to prioritize specific federal investments in climate adaptation, the weight of the transition falls on multiple levels. Municipalities locally finance energy insulation, shaded parks, resilient water supply systems, and infrastructure reinforcements against floods and landslides. Employers face rising costs for climate control, workplace safety in extreme heat, and absenteeism due to thermal discomfort. Workers suffer from reduced productivity, health risks in exposed sectors (construction, agriculture, transport), and stress from climate vulnerability. Consumers see food prices remain volatile in the face of crop losses and drought management. ### How to follow the federal political debate on the climate Mazzone's request will be debated in Swiss democratic forums in the coming months. The Federal Chambers, particularly specialized committees like the CATAE (Environment, Spatial Planning and Energy Committee), will take positions on how to redesign federal climate governance and allocate public resources. Swiss citizens who wish to influence this process have effective tools at their disposal: follow parliamentary procedures on parlament.ch to track climate-related motions and initiatives; contact your parliamentary representatives (National Councilors and Councilors of States) to highlight local climate adaptation priorities in your cantons; monitor federal consultations when the Federal Council proposes ordinances and decrees on environmental protection and energy transition. The articulation of the federal debate depends on the democratic pressure exerted by citizens, businesses, trade unions, and environmental organizations. The Greens' position is one piece of a broader mosaic of pushes for a more ambitious and funded central climate policy. ### How to stay informed and monitor personal impact To understand how federal budget choices—and thus taxes and public investments—directly impact your salary, benefits, and quality of life, consult the Frontaliere Ticino salary and tax calculator.
