Swiss climate disclosure tagging -
so you can focus on what you do best.
Switzerland's Ordinance on Climate Disclosures requires large Swiss-listed companies, banks and insurers to publish climate-related financial disclosures aligned with the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD). For the first time, these disclosures must be digitally tagged in iXBRL - making them machine-readable and comparable across companies.
The tagging can be applied using either the GRI or ESRS taxonomy. With no central filing portal and limited regulatory guidance on format, companies are largely left to self-interpret - making expertise in emerging taxonomies essential.

Does it affect me?
You are in scope if your organisation is a Swiss-listed company, a Swiss subsidiary contributing more than 20% of assets or turnover to a listed Swiss group, or a FINMA-regulated entity such as a bank, insurer or asset manager. The rules apply to groups with 500+ employees and either a balance sheet total above CHF 20 million or annual turnover above CHF 40 million.
What do I need to do?
Your sustainability report must be digitally tagged in iXBRL using either the GRI or ESRS taxonomy, depending on your reporting framework. ARKK supports tagging in both GRI and ESRS, with the final tagged report published on your company website.
What's the deadline?
The Ordinance applies to financial years beginning on or after 1 January 2025. Companies with a 31 December year end must publish their first tagged sustainability report by 30 June 2026, while other companies must publish within six months of year end. Tagging should begin early, as reports often go through multiple revisions.
