The global shift toward standardized sustainability reporting is gaining momentum, and the UK is at the forefront with its introduction of the UK Sustainability Disclosure Standards (UK SRS), due to be implemented from January 1, 2025. Developed by the UK government through the Department for Business and Trade (DBT) and guided by the Financial Reporting Council (FRC), these standards aim to align UK corporate sustainability reporting with the International Sustainability Standards Board (ISSB). For multinational companies, especially those with operations, investments, or listings in the UK, understanding the UK SRS is critical to maintaining compliance, reputation, and investor confidence. The UK SRS will initially adopt the ISSB's IFRS S1 and S2 standards, bringing a consistent and decision-useful framework for reporting climate and sustainability risks (UK Government announcement).
At its core, the UK SRS incorporates the IFRS S1 (General Requirements for Disclosure of Sustainability-related Financial Information) and IFRS S2 (Climate-related Disclosures) developed by the ISSB, which was established under the IFRS Foundation in response to demands from investors and regulators for clear and comparable ESG data.
The UK SRS framework will require companies to disclose:
Crucially, these disclosures must be integrated into the annual financial report and subject to assurance, enhancing the credibility of reported data. The standards also support double materiality, meaning companies must assess both how sustainability issues affect them financially and how their operations affect the environment and society.
The UK SRS will have direct implications for UK-incorporated companies, especially Public Interest Entities (PIEs) such as listed companies, banks, and insurance firms. However, multinational corporations headquartered elsewhere but operating in the UK, or raising capital from UK investors, will likely need to align their disclosures with the UK SRS to meet stakeholder expectations and avoid regulatory scrutiny.
The FRC and FCA (Financial Conduct Authority) will work jointly to oversee adoption, with a phased implementation likely based on company size and sector. Companies already reporting under the Task Force on Climate-related Financial Disclosures (TCFD) framework or preparing for EU’s Corporate Sustainability Reporting Directive (CSRD) may find some alignment, as the ISSB standards were designed to build on TCFD principles. However, differences in materiality definitions and scope (particularly around Scope 3 emissions) may require adjustments.
Moreover, firms listed on both the London Stock Exchange and European markets will need to ensure interoperability between UK SRS, EU ESRS, and potentially SEC climate rules in the U.S. This increases the demand for harmonized ESG data collection systems and internal governance structures that can support multi-jurisdictional compliance.
To prepare effectively for the UK SRS in 2025, companies should undertake the following steps:
Many companies are already taking these steps, driven by increasing investor demand. According to a 2024 survey by PwC, 72% of UK institutional investors said they will prioritize companies aligned with ISSB standards by 2026 (PwC Sustainability Reporting Survey).
The introduction of the UK Sustainability Disclosure Standards marks a pivotal evolution in corporate sustainability reporting. While initially UK-focused, its alignment with ISSB positions the UK SRS as a de facto global benchmark. For international companies, particularly those already navigating a complex regulatory landscape that includes CSRD, SEC climate rules, and TCFD requirements, UK SRS adds another layer—but also an opportunity.
By proactively aligning with the UK SRS, companies can demonstrate climate governance maturity, reduce regulatory risk, and gain a competitive edge in attracting ESG-focused investors. The message is clear: sustainability reporting is no longer a peripheral issue—it's a central pillar of financial and strategic disclosure in the UK and beyond.
