**Purpose of the paper**

This paper provides a summary of the agenda and papers for the UK Sustainability Disclosure Technical Advisory Committee (TAC) meeting, on 8 July 2025.

**Summary of the Issue**

The TAC was tasked by the Department for Business and Trade[^1] (DBT) to assess the IFRS Sustainability Disclosure Standards, from a technical perspective, and provide advice[^2] to the Secretary of State on whether their endorsement would be conducive to the long-term public good in the UK.

In addition to the TAC, the Policy Implementation Committee (PIC) is responsible for ensuring that any endorsed standards are implemented in a way that aligns with the mandates of UK government departments and regulator representatives.

On 18 December 2024, the TAC concluded[^3] that the endorsement of both IFRS S1 General Requirements for Disclosure of Sustainability-related Financial Information (IFRS S1) and IFRS S2 Climate-related Disclosures (IFRS S2), was likely to be conducive to the long-term public good in the UK. The TAC will continue to meet monthly during 2025 (refer Appendix A).

The UKEB is represented on the Committee by a Board Member, who is appointed as a full TAC member to reflect the need to maintain connectivity between UK adopted international accounting standards and UK Sustainability Reporting Standards.

<a class="section__global-number" href="#paragraph-A5" id="paragraph-A5">A5.</a> The TAC paper noted that DBT[^6] has requested that the Committee undertakes a proportionate analysis of the ISSB's enhancements to the SASB Standards and identifies any implications for UK Sustainability Reporting Standards.

<a class="section__global-number" href="#paragraph-A6" id="paragraph-A6">A6.</a> The TAC Secretariat proposed project management approaches to coordinate responses to the EDs and requested guidance on an approach from the TAC.

    ### ISSB meeting
    
    #### June 2025
    
    <a class="section__global-number" href="#paragraph-B1" id="paragraph-B1">B1.</a> The ISSB met in Beijing on 18 June 2025 and ratified proposed amendments to enhance SASB standards (SASB Exposure Draft). The SASB Exposure Draft proposes amendments to nine[^1] high priority Standards and targeted amendments to another 41 Standards[^2] to ensure consistent disclosure guidance across SASB Standards.
    
    <a class="section__global-number" href="#paragraph-B2" id="paragraph-B2">B2.</a> The ISSB also tentatively approved amendments to the Industry-based Guidance on Implementing IFRS S2 to maintain alignment with the proposed changes in the SASB Exposure Draft.
    
    <a class="section__global-number" href="#paragraph-B3" id="paragraph-B3">B3.</a> The ISSB intend to begin the balloting process for the exposure draft of proposed amendments to the IFRS S2 industry-based guidance and to publish both Exposure Drafts in July 2025[^3].
    
    ### IFRS Foundation
    
    <a class="section__global-number" href="#paragraph-B4" id="paragraph-B4">B4.</a> As part of the London Climate Action Week[^4] the IFRS Foundation held sessions on climate-transition plans and accelerating the integration of climate-related matters into corporate and investment decision-making.
    
    <a class="section__global-number" href="#paragraph-B5" id="paragraph-B5">B5.</a> The Foundation also published guidance on disclosures relating to net zero transition plans[^5] which builds on disclosure-specific material developed by the Transition Plan Taskforce. The guidance is intended to be used by jurisdictions adopting or otherwise using ISSB Standards[^6].
    
    <a class="section__global-number" href="#paragraph-B6" id="paragraph-B6">B6.</a> The Foundation published an article regarding using ISSB Standards with the revised Management Commentary Practice Statement[^7]. It was noted that it was anticipated to facilitate better connections between financial statements and sustainability-related financial disclosures.
    
    <a class="section__global-number" href="#paragraph-B7" id="paragraph-B7">B7.</a> At the annual IFRS Conference the IASB and ISSB provided a joint update, and a workshop was held with a panel of investors, preparers and auditors which discussed perspectives on connectivity between financial statements and sustainability-related financial disclosures.
    
    ### UK updates
    
    <a class="section__global-number" href="#paragraph-B8" id="paragraph-B8">B8.</a> The Department for Business and Trade (DBT) opened a consultation[^8] on an Exposure draft of UK Sustainability Reporting Standards: UK SRS S1 and UK SRS S2. These are based on IFRS S1 General Requirements for Disclosure of Sustainability-related Financial Information and IFRS S2 Climate-related Disclosures. The government has proposed a limited number of minor amendments which include:
    
    <ol markdown="1" type="a">
    
  • Amending the instruction regarding SASB materials in IFRS S1 and IFRS S2 from 'shall refer to and consider' to 'may refer to and consider'.
  • Emissions reporting can use any appropriate classification standard and is not restricted to the Global Industry Classification Standard (GICS).
  • Entities can report on 'climate-first' for the first two years instead of one, before having to report on wider sustainability risks and opportunities.
  • The removal of a transition relief to allow delayed sustainability disclosure until after financial statements have been published.
  • Removal of the 'effective date' clauses in both Standards
  • B9. The consultation also seeks evidence on the costs and benefits of using the UK SRS. This evidence will inform future government decisions when it considers whether to require entities to report information using the Standards. The consultation will close on 17 September 2025.

    <a class="section__global-number" href="#paragraph-B10" id="paragraph-B10">B10.</a> The UK Sustainability Disclosure Technical Advisory Committee (TAC) is scheduled to meet on 8 July 2025. Please refer to the TAC Update paper in the UKEB July public papers for noting.
    
    ### European updates
    
    <a class="section__global-number" href="#paragraph-B11" id="paragraph-B11">B11.</a> The European Financial Reporting Advisory Group (EFRAG) submitted a detailed progress report to the European Commission outlining proposed simplifications to European Sustainability Reporting Standards (ESRS) in June. The proposed revisions seek to reduce the administrative burden on companies while preserving the core goals of the EU Green Deal. Key simplifications include:
    
    <ol markdown="1" type="a">
    
  • Reduced mandatory data points.
  • A clearer distinction between mandatory and voluntary disclosures.
  • Refinements to the double materiality assessment to make it more strategic in nature.
  • Improved interoperability with standards such as the ISSB's IFRS S1 and IFRS S2.
  • B12. EFRAG will conduct a public consultation and then submit final technical advice to the European Commission (EC) by October 2025. It is anticipated that the EC will adopt the revised ESRS via a delegated act by the end of 2025.
