Local adoption of IFRS S1 / S2 (ISSB Standards)

Chile's Ley REP requires producers of priority products to organize and finance collection and recycling of their post-consumer waste, individually or through collective management systems. Targets are in force for tyres (DS 8/2019, from January 2023) and packaging (DS 12/2020, from September 2023). The portable battery and EEE decree (DS 22/2025) was published in May 2026; its general collection and recovery target starts at 3% in the first year and rises to 45% from the tenth year, applying from May 2028. The lubricant oils decree was annulled by the courts in August 2026, and decrees for batteries and textiles are still being drafted.

UK SRS S1 and S2 are the UK government's endorsed versions of IFRS S1 and S2, published on 25 February 2026 for voluntary use. Voluntary users can apply the Scope 3 and non-climate reliefs with no time limit. The FCA has consulted on listing rules that would make UK SRS S2 climate reporting mandatory for listed companies, with Scope 3 emissions and UK SRS S1 non-climate reporting on a comply-or-explain basis.

Enforcement

Voluntary at publication. FCA proposes mandatory UK SRS S2 for listed issuers (Scope 3 and broader sustainability on comply-or-explain).

Effective date

Voluntary use: no effective date (entities apply the standards when they choose). FCA proposal, subject to the final policy statement: rules in force 1 January 2027 for accounting periods beginning on or after 1 January 2027; using the transitional reliefs, Scope 3 reporting from periods beginning on or after 1 January 2028 and UK SRS S1 non-climate reporting from periods beginning on or after 1 January 2029.
