Sustainability regulations are rapidly moving into implementation. Across regions, frameworks are being introduced, refined, and enforced, expanding the scope from core disclosures to value chains and assurance.
This roundup covers key global sustainability framework updates from January to March 2026, focusing on what’s now in force and what organisations should prepare for next.
A) European Union
A1. ESRS simplification advances, easing future reporting requirements

Impacted sectors: All listed and large companies
Status: In Force
What to watch
- The UK Sustainability Reporting Standards (UK SRS) have been formally published, establishing the UK’s baseline for sustainability disclosures aligned with ISSB standards.
- The framework introduces UK-specific modifications and replaces the earlier TCFD-based reporting approach. Voluntary application begins from FY2026.
Why it matters
Organisations should begin aligning internal reporting processes with ISSB principles while accounting for UK-specific adjustments. Early adoption can help streamline future compliance and strengthen investor-facing disclosures.
B2. UK introduces ISAS 5000, strengthening the assurance landscape for sustainability reporting
Date: January 2026
Aligned with: IAASB, ISSB
Impacted sectors: Auditors, assurance-obligated corporates
Status: In Force
What to watch
- The UK has introduced ISAS 5000, a dedicated sustainability assurance standard aimed at improving the quality and consistency of assurance engagements.
- The standard provides a structured framework for auditors assessing sustainability disclosures.
Why it matters
As assurance becomes integral to ESG reporting, organisations should prepare for more rigorous verification processes. Strengthening data controls and audit readiness will be critical to meeting evolving assurance expectations.
C) China
China advances climate disclosure with IFRS-aligned trial standard
Date: January 5, 2026
Aligned with: IFRS S2, Dual Carbon
Impacted sectors: All corporates (trial phase)
Status: In Force (Trial)
What to watch
- China’s Ministry of Finance has issued Corporate Sustainable Disclosure Standard No. 1 – Climate (Trial), marking a significant step toward standardised climate disclosures.
- The framework closely mirrors IFRS S2 and is currently being implemented on a trial basis, with expectations of a transition toward mandatory adoption over time.
Why it matters
Organisations operating in or engaging with the Chinese market should begin aligning with IFRS-based climate disclosure practices early. The trial phase offers a window to build internal capabilities ahead of eventual mandatory requirements.
D) Japan
D1. Japan initiates SSBJ voluntary phase, signalling transition toward mandatory ISSB-aligned reporting
Date: January 2026
Aligned with: ISSB S1 & S2, IFRS

- While currently voluntary, mandatory adoption is set to begin from FY2027 for companies with a market capitalization of ¥3 trillion or more.
- The Financial Services Agency (FSA) is also introducing a phased approach to Scope 3 emissions disclosure.
Why it matters
Listed companies should use the voluntary window to align with ISSB-based reporting and prepare for upcoming mandatory requirements. Early action on Scope 3 data collection and supply chain engagement will be critical as disclosure expectations evolve.
D2. Japan rolls out GX2040 subsidy framework to accelerate clean energy demand
Date: January 2026
Aligned with: Paris Agreement, Japan NDC
Impacted sectors: Energy, Manufacturing, Data Centres, Technology
Status: In force
What to watch
- Japan has introduced the GX2040 Clean Energy Demand Subsidy Framework, a ¥200B+ initiative spanning five years to incentivise the consumption of decarbonised electricity.
- The scheme is a key component of the country’s broader GX2040 Vision, aimed at accelerating the transition to a low-carbon economy.
Why it matters
Organisations in energy-intensive sectors should evaluate eligibility and potential cost advantages from adopting clean energy sources. The framework signals increasing policy support for demand-side decarbonisation, making early participation strategically beneficial.
E) South Korea
South Korea outlines roadmap for mandatory KSSB adoption, signalling phased ISSB alignment
Date: March 2026 (draft roadmap for public consultation)

K) India
India updates climate goals, raising ambition under its 2035 NDC
Date: March 2026
Aligned with: Paris Agreement, UNFCCC
Impacted sectors: Energy, Manufacturing, Infrastructure, All sectors
Status: In force
What to watch
- India has approved its updated Nationally Determined Contributions (NDCs) for the 2031–2035 period, setting enhanced climate targets.
- These include a 47% reduction in emissions intensity (from 2005 levels), achieving 60% of installed power capacity from non-fossil fuel sources, and creating a carbon sink of 3.5–4.0 billion tonnes of CO₂ equivalent by 2035.
- The updated targets build on India’s earlier commitments, many of which were achieved ahead of schedule, and signal a continued push toward clean energy expansion and low-carbon growth.
Why it matters
Organisations should anticipate stronger policy alignment toward decarbonisation, particularly in energy sourcing, manufacturing, and infrastructure. The updated NDCs reinforce the direction of travel toward cleaner energy systems and may influence future regulatory, disclosure, and transition expectations across sectors.
Conclusion
Sustainability reporting is no longer a peripheral exercise, it is becoming a core business requirement, shaped by converging global standards and increasing regulatory scrutiny.
As frameworks evolve and expectations expand, organisations need systems that can adapt across jurisdictions, frameworks, and disclosure requirements.
At Credibl, we support this shift by enabling organisations to align with multiple global frameworks, streamline reporting, and build a connected sustainability data ecosystem designed to scale with a rapidly changing regulatory landscape.
