Forty Jurisdictions Adopt ISSB Sustainability Reporting Standards

The International Sustainability Standards Board (ISSB) has seen its global baseline for sustainability reporting adopted or legislated by forty jurisdictions, which collectively account for 60% of global output. These disclosure frameworks aim to attract global transition capital by providing verified evidence of environmental records.

Several emerging economies implemented specific rules in January 2026, including Brazil, Chile, Qatar, and Mexico. Nigeria also committed to a phased transition toward mandatory ISSB-aligned reporting for public-interest entities. In India, the Securities and Exchange Board of India is currently phasing in audit-grade assurance for the thousand largest listed companies, with a target completion date of 2026-27.

This reporting data is being integrated into green deposits, sovereign green bonds, and a developing climate finance taxonomy. The shift in financial rule-making is positioning cities such as Mumbai and Brasilia as central hubs for these standards, alongside established centers like New York and Brussels.
