Introduction

In February 2026, the United Kingdom formally published the UK Sustainability Reporting Standards (UK SRS), marking a major step toward standardized sustainability disclosure. The framework aligns closely with the International Sustainability Standards Board (ISSB) global baseline and is expected to shape the future of corporate sustainability disclosure across the UK economy. For global companies operating in the UK market, the release of UK SRS signals a transition toward more consistent and investor focused sustainability reporting.

The first official standards consist of UK SRS S1 and UK SRS S2, which establish requirements for sustainability related financial disclosures and climate related disclosures. These standards are built on the structure of IFRS S1 and IFRS S2 developed by the ISSB. Their publication represents an important milestone in the UK’s broader strategy to strengthen transparency around sustainability risks, climate transition plans, and long term corporate resilience.

Key Takeaways

• The UK government formally published the first UK Sustainability Reporting Standards (UK SRS) in February 2026, aligning the framework with the global ISSB baseline.
• The new framework consists of two standards: UK SRS S1 for general sustainability disclosures and UK SRS S2 for climate related disclosures.
• The standards are closely based on ISSB IFRS S1 and IFRS S2, supporting global consistency in sustainability reporting.
• UK SRS is designed to provide investor focused sustainability information that explains how sustainability issues may affect enterprise value.
• Although the standards are currently voluntary, regulators are consulting on how they may become mandatory for listed and potentially large private companies in the future.
• Companies operating in the UK should begin preparing for ISSB aligned sustainability reporting structures and disclosures.

What Are the UK Sustainability Reporting Standards (UK SRS)?

UK Sustainability Reporting Standards are the UK government’s approach to implementing a globally aligned sustainability disclosure framework. The standards aim to provide investors with decision useful information about sustainability risks and opportunities that could affect enterprise value.

The framework mirrors the architecture of the ISSB standards and focuses on integrating sustainability disclosures into financial reporting structures. This approach supports comparability across jurisdictions and improves the reliability of sustainability data used by investors and regulators.

At launch, the UK SRS framework contains two core standards.

Standard	Focus Area	Based On
UK SRS S1	General sustainability related financial disclosures	IFRS S1
UK SRS S2	Climate related disclosures	IFRS S2

The Four Core Pillars of UK SRS

The UK SRS framework is structured around four core disclosure pillars that guide how companies report sustainability information.

• Governance
  Companies must disclose how boards and senior management oversee sustainability related risks and opportunities.
  
• Strategy
  Organizations should explain how sustainability issues affect business strategy, financial planning, and long term value creation.
  
• Risk Management
  Companies are expected to describe the processes used to identify, assess, and manage sustainability related risks.
  
• Metrics and Targets
  Businesses must report measurable indicators used to track sustainability performance and progress toward targets.

UK SRS S1 – General Requirements for Sustainability Disclosures

• Establishes the overall framework for sustainability related financial disclosures.
• Requires companies to disclose information across the four pillars: Governance, Strategy, Risk Management, and Metrics and Targets.
• Focuses on sustainability risks and opportunities that could influence enterprise value.

UK SRS S2 – Climate Related Disclosures

• Provides detailed reporting requirements specifically related to climate change.
• Requires disclosure of greenhouse gas emissions including Scope 1, Scope 2, and where relevant Scope 3 emissions.
• Requires disclosure of climate risks and opportunities that could affect business performance.
• Includes information on climate transition plans, scenario analysis, and resilience of business strategies.

What May Happen Next for UK Sustainability Reporting

Although UK SRS S1 and UK SRS S2 have now been published, the standards are currently voluntary. The UK government and regulators are now considering how the framework could be integrated into mandatory corporate reporting requirements in the future.

One important development is the ongoing consultation by the Financial Conduct Authority (FCA). The regulator is proposing amendments to the UK Listing Rules that would require listed companies to report sustainability information in line with the new UK Sustainability Reporting Standards.

If adopted, these proposals would replace the current climate disclosure requirements aligned with the Task Force on Climate related Financial Disclosures with a broader reporting framework based on UK SRS. The consultation is open until 20 March 2026.

Beyond listed companies, the UK government has also indicated that it intends to explore extending the standards to large private companies. While the thresholds and timing have not yet been confirmed, policymakers have signaled that wider adoption of UK SRS could be considered as part of future sustainability reporting reforms.

Industry stakeholders are also calling for greater clarity on how the standards could become mandatory for companies within the scope of future regulation. As the consultation process continues, businesses operating in the UK are closely monitoring how UK SRS may evolve from a voluntary framework into a formal reporting requirement.

How UK SRS Compares with Other Sustainability Frameworks

The UK SRS framework is designed to fit within the broader global ecosystem of sustainability reporting standards.

Framework	Region	Reporting Focus	Materiality Approach
UK SRS	United Kingdom	Investor focused sustainability and climate disclosures	Financial materiality
ISSB IFRS S1 and S2	Global baseline	Financially material sustainability risks and opportunities	Financial materiality
EU CSRD	European Union	Comprehensive ESG disclosure	Double materiality

What Companies Should Disclose Under UK SRS

UK SRS is designed to ensure that companies provide investors with clear and comparable information about sustainability risks and opportunities that may affect enterprise value.

Disclosure Category	What Companies Should Disclose
Governance	Board oversight of sustainability risks and opportunities, management responsibilities, and governance processes
Strategy	How sustainability risks and opportunities affect business strategy and financial planning
Risk Management	Processes used to identify, assess, and manage sustainability risks
Metrics and Targets	Quantitative indicators used to measure sustainability performance including emissions and climate targets

For climate disclosures under UK SRS S2, companies are also expected to disclose:

• Greenhouse gas emissions data (Scope 1, Scope 2, and where relevant Scope 3)
• Climate transition plans
• Climate scenario analysis
• Resilience of business strategies under different climate pathways

How Companies Should Prepare for UK Sustainability Reporting

Although the standards themselves represent an important milestone, companies should view them as part of a broader regulatory transition.

Organizations can begin preparing by taking several steps:

1. Review existing sustainability and climate disclosures
   
2. Align internal reporting structures with ISSB disclosure categories
   
3. Improve governance and oversight of sustainability risks
   
4. Develop reliable systems for emissions and sustainability data
   
5. Integrate sustainability considerations into financial strategy

Companies that already report using frameworks such as TCFD or ISSB may find that many of their existing processes align with UK SRS expectations.

Frequently Asked Questions
