Climate reporting law guide

Know which climate report is due—and what standard it must follow.

California, Australia, and the EU all require climate-related reporting, but they do not ask for the same report. Compare the current status, timing, scope, and framework for SB 261, ASRS, and CSRD.

California SB 261

The statute set January 1, 2026 as the first deadline, then every two years. CARB says it will not enforce that date while the Ninth Circuit injunction remains in place and will announce an alternate date, if appropriate, after the appeal is resolved.

What report is expected

Public climate-related financial risk report

What the law asks for

SB 261 requires disclosure of material physical and transition risks and the measures adopted to reduce and adapt to those risks. Reports may be consolidated at the parent-company level.

A publicly accessible climate-related financial risk report posted on the company website. It should follow the 2017 TCFD recommendations, a successor, or a qualifying equivalent. Incomplete reports should explain gaps and the steps toward complete disclosure.

Do not confuse it with:

SB 261 is a climate-related financial risk report. It is not California SB 253’s greenhouse-gas emissions report.

Framework decoder

The frameworks overlap—but they do not ask for the same thing.

TCFD established the common climate-risk architecture. IFRS S2 adds a more prescriptive investor-focused standard. ESRS goes further with double materiality and broader sustainability impacts.

Common starting point

TCFD recommendations

The four-pillar architecture: governance, strategy, risk management, and metrics and targets.

Builds directly on TCFD

IFRS S2

Financial materiality

A more prescriptive global baseline focused on climate-related risks and opportunities that could affect enterprise value.

Separate EU standards

ESRS / CSRD

Double materiality

A broader sustainability reporting system that assesses both financial effects and the company’s impacts on people and the environment.

Jurisdictional adaptation

Australia AASB S2

Based on IFRS S2, modified to operate as Australia’s mandatory standalone climate standard.

Connection—not equivalence

Interoperability guidance

Shared climate disclosures can reduce duplication, but ESRS and IFRS S2 retain different materiality lenses and legal requirements.

Physical risk
Transition risk
Scenario analysis
Metrics & targets

Shared subject matter does not mean identical scope, materiality, measurement, or filing requirements.

What each framework expects

A practical comparison of core climate assessment and disclosure expectations. “Partial” means the topic is addressed, but with less prescription, conditional scope, or available transition relief.

Double materiality

Financial effects on the company plus impacts on people and planet

TCFD

Financial materiality focus

IFRS S2

Investor-focused financial materiality

ESRS / CSRD

Core ESRS assessment principle

The practical rule: IFRS S1 and IFRS S2 incorporate all TCFD recommendations, but a TCFD-aligned report is not automatically IFRS-compliant. ESRS and IFRS S2 share substantial climate content, but ESRS adds impact materiality and is not an equivalent standard.

Legal scope, court orders, regulator guidance, and implementation dates can change. Confirm your entity’s obligations with counsel and the relevant regulator before filing or publishing.

From requirement to report

Turn the requirement into a reviewable climate-risk report.
