Geneva’s Grand Council approves CHF 15 million for biodiversity

On 2 October 2026, Geneva’s Grand Council approved CHF 15 million to strengthen the canton’s ecological infrastructure. According to the Keystone-ATS report carried by Radio Lac, the bill passed by 44 votes to 37. For municipalities and private property owners, the decision highlights the contribution that buildings and their surroundings can make to biodiversity.

Funding split between investment and grants

The package has two complementary components:

• CHF 5 million for studies and investment to deliver practical measures.
• CHF 10 million in grants, notably for municipalities and private stakeholders.

The funding is intended to help implement the Geneva Biodiversity Strategy 2030. The adopted bill reflects a parliamentary compromise, with a smaller budget than originally proposed.

Which measures are covered?

The programme addresses several types of intervention across the canton and within the built environment:

• Creating green roofs, making more space for nature on buildings.
• Restoring wetlands, which provide important habitats for many species.
• Adapting structures that trap small and medium-sized wildlife, reducing hazards associated with existing infrastructure.
• Upgrading lighting to support dark ecological corridors, maintaining connected areas of darkness for nocturnal species.

According to the same report, crossings for large wildlife were explicitly excluded from the programme.

What does this mean for property owners?

The allocation of some grants to private stakeholders makes the credit relevant to owners of houses, apartment buildings and land. Roof renovations or changes to outdoor areas can provide an opportunity to consider biodiversity alongside other project requirements.

Approval of the credit does not, however, guarantee a grant for every project. The report consulted does not specify grant rates, funding caps or application dates. Owners should confirm the applicable conditions with the relevant authorities before including public funding in their budgets.

Plan ahead without assuming eligibility

From a property perspective, a prudent approach is to identify possible interventions, assess technical feasibility and calculate both installation and maintenance costs. For a green roof, for example, qualified professionals should examine structural load capacity and waterproofing.

Our assessment: the decision encourages an approach to property that goes beyond the building itself to consider its relationship with the landscape and natural habitats. On its own, it does not establish an increase in property values or new general obligations for owners.
