On 31st January 2022, the Climate Disclosure Standards Board (CDSB) was consolidated into the IFRS Foundation to support the work of the newly established International Sustainability Standards Board (ISSB). While this site and its resources remain relevant for preparers looking to improve sustainability disclosure until such time as the ISSB issues its IFRS Sustainability Disclosure Standards on such topics, no further work or guidance will be produced or published by CDSB. For further information please visit the IFRS website.


The CDSB Framework aligns as far as possible with features of the mainstream-reporting model.

The CDSB Framework is designed for the purpose of reporting climate change-related and environmental information in mainstream reports. The materiality position therefore adopted by CDSB aligns as far as possible with features of the mainstream-reporting model, so that climate-change related and environmental information may be prepared and presented in a structured way within the architecture of existing mainstream reports.

The following considerations have guided CDSB's thinking on relevance and materiality based on research and technical discussions:

  1. Consistency with materiality as applied in the mainstream-reporting model
  2. Materiality and proportionality
  3. Materiality determination process and outcome
  4. Clarification of scope, stakeholder group and time frames for materiality
  5. Materiality of climate change 
  6. Trends in reporting

CDSB will continue to monitor the IASB's Disclosure Initiative "Principles of Disclosure" and Conceptual Framework projects and the work of SASB, IIRC and others, and recognises that new thinking on materiality is likely to emerge over time.
