ESG reporting rules by country

Compare mandatory ESG and climate reporting rules by country, including scope, start dates, ISSB alignment, Scope 3 and assurance requirements.

Environmental, social and governance reporting is converging around common standards, but it is not becoming one global filing rule. Company thresholds, start dates, Scope 3 reliefs and assurance duties still depend on the jurisdiction.

Use this directory to compare reporting rules across 13 major jurisdictions, identify the rule owner and open the relevant regulator source or detailed TPB guide. International Sustainability Standards Board (ISSB) alignment is shown separately from the local duty to file.

Comparison notes

Where the rules differ

The same standard name can lead to different reporting work once local thresholds, filing locations and transition reliefs are applied.

Law, listing rule or voluntary standard

A standard can be available without being mandatory. The UK and Brazil currently illustrate why availability and filing duty need separate checks.

Climate-only or sustainability-wide

Australia and New Zealand focus on climate disclosure. EU reporting reaches across environmental, social and governance topics through double materiality.

Reporting period or filing date

A rule often applies to a financial year before the report appears. Map the first period in scope separately from the first publication deadline.

Scope 3 relief

Scope 3 can be mandatory, deferred, voluntary or tied to materiality. ISSB alignment alone does not identify the first year for value-chain emissions.

Assurance

Some frameworks phase limited assurance after reporting begins. Others cover only emissions or have not settled an economy-wide timetable.

Group and foreign-issuer scope

Revenue, assets, listing status and local activity can bring an overseas group into scope. The current local rule remains decisive.
