UK Government Publishes First ISSB-Aligned Sustainability Reporting Standards
The UK government has published the first set of UK Sustainability Reporting Standards, marking an important milestone in the evolution of corporate sustainability disclosure. The new standards align closely with the global framework developed by the International Sustainability Standards Board (ISSB) and aim to improve the consistency and comparability of sustainability information reported by UK businesses.
A New Step in UK Sustainability Reporting
On 25 February 2026, the UK government’s Department for Business and Trade released the first official UK Sustainability Reporting Standards (UK SRS) for voluntary use by organisations across the country.
The new standards represent the UK’s adoption of internationally recognised sustainability disclosure rules developed by the ISSB. They are designed to improve transparency around how businesses manage sustainability risks and opportunities that may affect their financial performance.
Initially, companies can choose to apply the standards voluntarily while the government considers how they may be introduced into mandatory reporting requirements in the future.
What the New Standards Cover
The UK Sustainability Reporting Standards consist of two core disclosure frameworks.
The first is UK SRS S1, which sets out general requirements for reporting sustainability related financial information.
The second is UK SRS S2, which focuses specifically on climate related disclosures, including how organisations assess climate risks, measure emissions and plan for transition.
Together, these standards aim to ensure that sustainability information is presented alongside financial information in a way that helps investors, regulators and other stakeholders understand the long-term resilience of a business.
Built on Global Sustainability Reporting Standards
The UK SRS are closely based on the global sustainability disclosure standards issued by the ISSB in June 2023. These original standards, known as IFRS S1 and IFRS S2, were created to establish a global baseline for sustainability related financial disclosures.
By aligning with this international framework, the UK government aims to ensure that sustainability information reported by UK businesses remains comparable with companies operating in other areas.
This alignment is seen as particularly important for investors and financial markets, where consistent sustainability data can support better capital allocation and risk assessment.
How the Framework Was Developed
The path to the final standards began in June 2025, when the UK government launched a consultation on draft UK Sustainability Reporting Standards along with proposals on transition planning and sustainability assurance.
Feedback from businesses, investors and professional bodies helped shape the final framework that was published in February 2026.
The government also indicated that further work will take place to determine which organisations will eventually be required to report under the standards and how assurance of sustainability disclosures will be overseen.
What This Means for Businesses
Although the standards are currently voluntary, they represent a significant shift in how sustainability information is expected to be reported within the UK.
Many organisations may begin adopting the standards early to prepare for potential future regulatory requirements and to align with international reporting expectations. The framework is also expected to influence sustainability disclosures by listed companies as regulators explore aligning existing reporting rules with the UK SRS.
For businesses already reporting on climate risks or sustainability performance, the new standards provide a clearer structure and stronger link between environmental impacts and financial decision making.
The publication of the UK Sustainability Reporting Standards signals the next phase in the development of the UK’s sustainable finance framework. By aligning with international reporting standards while tailoring them for the UK market, the government aims to create a consistent system that improves transparency and supports investment in sustainable economic growth.
As regulatory expectations continue to evolve, organisations that begin aligning their reporting practices now are likely to be better prepared for future requirements and better positioned to demonstrate credible sustainability performance.
