Compensation projects in Switzerland

Reductions in greenhouse gas emissions achieved in projects and programmes in Switzerland can receive attestation and be used to compensate for emissions.

Compensation projects and programmes in Switzerland must follow a specific procedure. The critical step in this procedure is to demonstrate that the reductions are additional and would have not been achieved without the project/programme.

The CO2 Act and the associated CO2 Ordinance form the legal basis for the implementation of CO2 compensation in Switzerland. Recommendations on implementing these provisions can be found in the implementation notice (available in German, French and Italian).

Registered compensation projects in Switzerland

Compensation projects approved by the FOEN and the SFOE are registered. An overview of the compensation projects already registered, including project documentation, is available here:

Statistics on compensation projects

The administrative office for compensation publishes statistics on the registered compensation projects. The estimates of expected emissions reductions come from the application documents for the registered projects and programmes. A file containing the data as well as evaluations are made available for download:


The FOEN issues attestations for reductions achieved in Switzerland. The attestations may be sold to fuel importers that are required to compensate for their emissions. Attestations are not internationally recognized. They cannot be traded outside Switzerland. Attestations are issued and traded in the Emissions Trading Registry (CHA unit). Information regarding opening an account in the Emissions Trading Registry can be found here:

Eligible types of projects

Projects in the following categories are eligible:

  • Energy-efficiency (in terms of supply and demand)
  • Renewable energies
  • Mobility management
  • Wood products
  • Biofuels with high quality standards
  • Biological and geological carbon storage

The list of allowable project types can be continuously updated as needed. Projects that reduce emissions of methane, nitrous oxide or fluorinated gases are also eligible. Projects can also be carried out as programmes. These programmes include several projects that have a common purpose.

The full list of project types for which no attestation is issued can be found in the Annex 3 of the CO2 Ordinance:

Implementation of projects / programmes

Information on the process of implementing projects and programmes as well as templates for preparing the project/programme documentation is available here:
