Executive Summary
On 5 June 2026, the Federal Council adopted a postulate report and rejected nationwide legislative measures to improve waste heat utilization. Postulate 23.3020 from the Commission for the Environment, Spatial Planning and Energy of the National Council from February 2023 called for clarification on how waste heat from facilities such as waste incineration plants or data centers can be promoted. The Federal Council sees the existing model regulations of the cantonal energy directors (MuKEn) as the central instrument for waste heat utilization. It rejects a federal legal obligation or mandatory designation of waste heat sites in cantonal structural plans.

Clarus Lead
The rejection of national regulation signals a deliberate restraint by the federal government on energy infrastructure issues. It is based on the conviction that cantonal coordination through existing model regulations is more efficient than new federal laws. This has immediate consequences for municipalities and energy suppliers: they must build pressure at the cantonal level to integrate waste heat standards into local zoning regulations – a fragmented approach that could perpetuate differences between cantons.
Detailed Summary
Waste heat utilization aims to feed thermal waste from industrial facilities into thermal networks and distribute them as district heating to households and businesses. The Federal Council argues that legislation in the building sector is regulated at the cantonal level and therefore cantons are primarily responsible. The MuKEn – proposals from the Conference of Cantonal Energy Directors – represent a flexible instrument that cantons can incorporate into cantonal law without requiring national coercive measures.
The Federal Council recommends that cantons design their requirements so that unavoidable waste heat above a certain threshold must be discharged. Where cantonal law provides for waste heat utilization and district heating networks exist, municipalities can adapt their zoning regulations or initiate special-use planning. The Federal Council rejects further measures such as federal legal obligations or mandatory site designations in the cantonal structural plan as "neither purposeful nor appropriate to the level of governance."
Key Statements
- The Federal Council relies on cantonal self-regulation instead of national legislation
- MuKEn are the preferred instrument for promoting waste heat utilization
- Municipalities can adapt zoning regulations and special-use planning locally
- No federal legal obligation for waste heat utilization is envisaged
- Decentralized approach is intended to ensure flexibility and efficiency
Critical Questions
Evidence: What empirical data shows that MuKEn without national minimum standards actually lead to comprehensive waste heat utilization? Is an evaluation metric missing?
Conflicts of Interest: Do cantons with weak energy legislation benefit from this decentralized strategy while innovative cantons suffer competitive disadvantages?
Causality: Is the rejection of national measures based on federalist principle or on lobbying influence from industry that fears waste heat obligations?
Feasibility: How will cantons without district heating network infrastructure implement waste heat standards? Is a two-tier energy transition threatened?
Alternatives: Would an incentive model (taxes, subsidies) instead of regulation have led to waste heat utilization more quickly?
Side Effects: Does the rejection of structural plan designations delay the development of district heating networks in regions with waste heat potential?
