Principle-based provisions in Switzerland
As of 1 January 2025, Switzerland has introduced a targeted legal provision to combat greenwashing through Article 3 paragraph 1 letter x of the Unfair Competition Act (UCA). This new rule prohibits misleading climate-related claims in commercial communication. Specifically, any statement about the climate impact of a company, its products or services that cannot be substantiated by objective and verifiable evidence is deemed unfair. A key innovation is the reversal of the burden of proof: companies must now proactively demonstrate the accuracy of their environmental claims.
Greenwashing in asset management, more specifically, is also prohibited by law. Pursuant to the Swiss Collective Investment Schemes Act (CISA), the designation “collective investment scheme” must not provide any grounds for confusion or deception, in particular in relation to the investments. Moreover, the fund documents must be truthful.
In its Guidance 05/2021 on preventing and combating greenwashing, published on 3 November 2021, FINMA expresses its expectations in this context: on the one hand, regarding sustainability-related information at the fund level and, on the other hand, regarding a suitable organizational structure at institutional level for managing such products. In terms of fund level expectation, FINMA lists scenarios bearing high greenwashing risks. The examples range from obvious deception (e.g., the fund makes a reference to sustainability, although no sustainable investment strategy or policy is actually pursued) to vague statements (e.g., the fund makes a reference to sustainability by using terms such as “impact” or “zero carbon” without the stated impact or savings being measurable or verifiable). Regarding institutional level expectations, FINMA urges the integration of sustainability-related considerations into the existing corporate governance structures.
On 26 September 2022, the Asset Management Association Switzerland (AMAS) published a principle-based Self-regulation on transparency and disclosure for collective assets referring to sustainability (SR). Even though the self-regulation qualifies as independent, it imposes binding organizational, reporting and disclosure obligations for AMAS members launching and/or managing sustainability-related funds. The definition of the various investment approaches follows the Recommendations on Transparency and Minimum Requirements for Sustainable Investment Approaches and Products, jointly published by AMAS and the Swiss Sustainable Finance (SSF) in December 2021.
Since its initial publication in September 2022, the AMAS SR has undergone several amendments. Version 1.1 was released in November 2023, followed by version 2.0, which came into force on 1 September 2024, with various transition periods. Notably, version 2.0 introduced a formal requirement for independent assurance, mandating external verification of compliance with the self-regulatory framework as part of the prudential audit. The current version 2.1, dated 8 June 2025, reflects further refinements, particularly with respect to real estate funds. Following the release of SR 2.0, AMAS has published and regularly updated a Q&A document offering practical guidance on implementation and interpretation. The last update took place on 21 July 2025. A month prior, on 24 June 2025, detailed audit procedures were introduced, outlining amongst others the level of assurance, applicable assurance standards, the frequency of the assurance as well as management representations.
