Scaling the Standard 2026
Insights from CDP’s 2025 IFRS S2-aligned disclosures
Harmonization has never been more important; jurisdictions that account for approximately 60% of global GDP have already decided to use or are taking steps to introduce ISSB Standards in their legal or regulatory frameworks.
In 2024, CDP aligned its corporate questionnaire with the ISSB’s IFRS S2 Standard as its foundational baseline for climate disclosure, enabling companies worth nearly two-thirds of global market capitalization to disclose IFRS S2-aligned data in a structured and transparent way. CDP is the largest single source of consistent, globally comparable IFRS S2-aligned climate data for investors and decision-makers.
This global snapshot provides insight into the extent of disclosure against IFRS S2-aligned data points in CDP’s question bank, indicating where companies are advancing and where disclosure gaps remain.
Global analysis of IFRS S2 alignment through CDP
Companies already disclosing environmental data through CDP – representing two-thirds of global market capitalization – are on the path towards meeting new requirements in jurisdictions adopting the ISSB Standards.
Analysis is based on a subset of 10,413 corporate disclosures from 2025, representing companies headquartered in 100 countries.
of companies disclosed against at least 80% of IFRS-S2-aligned questions (up from 83% in 2024)
of companies disclosed against all IFRS-S2-aligned questions on governance (up from 85% in 2024)
of companies disclosed against all IFRS-S2-aligned questions on climate-related metrics
Gaining momentum
The majority of companies are responding to climate governance-related questions, with 88% disclosing against all aligned questions on the processes they use to manage their climate-related risks and opportunities. Risk management disclosures are also strong, with 83% disclosing against all aligned questions, a 25% increase on the previous year. This represents one of the most significant year‑on‑year response improvements across the IFRS S2-aligned questions and indicates that companies are increasingly disclosing the processes they use to identify, assess, prioritize and monitor climate‑related risks and opportunities.
While gaps remain in the extent of responses against other IFRS S2 components, improvements can still be seen. Climate-related metrics, the component with the lowest levels of complete response in 2025, saw 31% of companies disclosing against all aligned questions – a 6% increase from last year.
The findings below highlight key areas for companies to further the extent of their IFRS S2-aligned reporting as mandatory disclosure requirements approach.
How policymakers can collaborate with CDP
As more jurisdictions prepare to introduce ISSB-aligned disclosure requirements, CDP is uniquely positioned to support governments and policymakers with data and insights to assess market readiness, inform regulatory frameworks and identify opportunities for capital allocation. CDP also provides a globally accessible platform for disclosure of IFRS S2-aligned information and a means to track its uptake across the economy.
CDP has a proven track record in scaling the adoption of disclosure frameworks and standards. For example, our 2018 questionnaire alignment was a driver behind the mainstreaming of TCFD-aligned reporting globally, which subsequently informed the growth of mandatory sustainability reporting.

How to engage with CDP to align with ISSB
CDP is ISSB’s key global climate disclosure partner and the ISSB’s climate Standard is the foundational baseline for CDP’s climate disclosure. Together with the disclosed dataset, the questionnaire provides an effective tool to support companies on their path to IFRS S2 disclosure.
By disclosing through CDP between June and October 2026, companies will be able to share environmental data aligned with IFRS S2 – as well as other important standards and frameworks – with stakeholders and the wider global market.
