Summary

On June 12, 2026, the Federal Council adopted a multi-channel strategy for informing, warning, and alerting the population. Emergency messages will henceforth be distributed via multiple channels: mobile phone alerting (Cell Broadcast) from 2029, Alertswiss app/website, and sirens. Responsibility for stationary and mobile sirens will be fully transferred to the cantons. The emergency radio IBBK will remain in place for now; a decision is scheduled for the end of June 2027. The Federal Office of Civil Protection (BABS) will provide a new siren remote activation system by 2035.

The modernization of the alerting system addresses a critical vulnerability: previous channels do not reliably reach all population groups. Cell Broadcast closes this gap through direct access to all mobile phones without app installation – a standard already used by European countries. Simultaneously, the transfer of siren responsibility to cantons signals a restructuring of emergency accountability, although the majority of cantons rejected this in the consultation process. The decision against the cantonal position underscores the priority of cost efficiency and administrative streamlining.

Detailed Summary

The multi-channel strategy is based on the recognition that crisis communication requires redundant, independent channels. Cell Broadcast complements existing systems through technical immediacy: all mobile phones in a defined geographic area receive text messages without network dependency or prior registration. This system will become operational by 2029.

The Alertswiss platform (active since 2018) will be further developed with emphasis on accessibility and offline availability – an adaptation to user groups with limited internet access. The central core system for capturing and disseminating information will be renewed.

The Federal Council justifies the transfer of sirens to cantons with the separation of responsibilities and cost reduction. Although cantons had mostly objected in the consultation process, the Federal Council maintains this position – based on the argument of administrative efficiency and positive incentives for cantonal self-responsibility. The federal government retains control over central siren remote activation and will provide a new remote activation system by 2035.

The emergency radio IBBK remains under review. The Federal Council has tasked the Department of Defence, Civil Protection and Sports (VBS) with evaluating solution options for information provision in shelters by the end of June 2027 – a response to parliamentary demands for continued operation and feedback from the consultation process.

Key Statements

  • Cell Broadcast will be implemented as a new alerting channel by 2029 and reaches all mobile phones without registration
  • Siren relocation to cantons occurs despite cantonal opposition, with federal responsibility for central remote activation until 2035
  • Emergency radio IBBK remains in place for now; decision on future model by June 2027

Critical Questions

  1. Evidence: What data shows that Cell Broadcast has a significantly higher reach rate than existing apps (Alertswiss) in crisis situations? Were comparative studies from other European countries consulted?

  2. Conflicts of Interest: To what extent do federal budget cuts influence the decision to transfer siren management to cantons, despite their majority opposition?

  3. Causality: Is it assumed that cantons with full financing responsibility will maintain siren networks better than under cost-sharing? What alternatives (e.g., federal-cantonal cost models) were examined?

  4. Feasibility: How will it be ensured that all mobile network operators support and coordinate Cell Broadcast technically by 2029? What fallback options exist in case of technical failure?

  5. Shelters: Why is the decision on emergency radio postponed until June 2027? What new findings should be available by then?

  6. Cost Distribution: What total financial burdens will be incurred by cantons through the siren relocation, and how will disparities between wealthier and poorer cantons be addressed?
