Compensation projects in Switzerland

Reductions in greenhouse gas emissions achieved in emissions-reduction projects and programmes (CO2 compensation) in Switzerland can receive attestation and be used to compensate for emissions.

Just like international projects, 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.

Those obliged to compensate can initiate projects themselves. For this they will receive no attestations, but rather the emission reductions will be credited to them directly. Trading these emission reductions is not possible.

The CO2 Act and the associated CO2 Ordinance form the legal basis for the implementation of CO2 compensation in Switzerland. The FOEN in conjunction with the Swiss Federal Office of Energy (SFOE) has drawn up recommendations on implementing these new legal provisions and these are presented in the implementation notice on Projects to reduce emissions in Switzerland (available in German, French and Italian).

The FOEN issues attestations for reductions achieved in Switzerland. The attestations may be sold to companies that are required to compensate for their emissions. Attestations are not internationally recognized and are therefore not fungible with Kyoto certificates.

Attestations are issued and traded in the Emissions Trading Registry. Attestations (CHA) cannot be traded outside Switzerland and are reserved to be used exclusively by companies obliged to compensate.
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

Projects that reduce emissions of methane, nitrous oxide or fluorinated gases are also eligible.

The list of allowable project types can be continuously updated as needed.

Small projects can be bundled and viewed jointly.

Projects can also be carried out as programmes. These programmes include several projects that have a common purpose.

Projects which are not permitted include projects and programmes in the fields of nuclear energy, forestry, those involving CO2 storage in geologic sequestration sites, conversion from petrol- or diesel-driven vehicles to natural gas-driven vehicles (with the exception of vehicle fleets), conversion from oil-fired heating systems to gas-fired heating systems, indirect emissions reduction by means of research and development and information and advisory services.
