The IFRS Foundation's International Sustainability Standards Board (ISSB), at its extraordinary meeting on 4 April, announced additional transitional measures for companies applying its first two climate change standards S1 (General Requirements for Financial Disclosure on Sustainability) and S2 (Climate Disclosures). Thus, companies will be able to take advantage of the first year of implementation of the S1 and S2 standards to familiarize themselves with them and develop and implement a management system that allows them to produce high-quality reports that satisfy investors. In summary, during the first year, companies applying to ISSB standards will have to provide only information on climate-related risks and opportunities and not sustainability, so they will not have to submit comparative information on Scope 3 greenhouse gas emissions, nor should they use the Greenhouse Gas Protocol to measure emissions. Complete information should be reported from the second year of implementation of the standards.

In May 2023, ISSB will set the following priorities: biodiversity, human capital, human rights, and integration in reporting, as recently reported.
