Reporting, Disclosure & Frameworks
Climate disclosure
The practice of companies and financial institutions publicly reporting climate-related risks, opportunities, governance, strategy and emissions — now shifting from voluntary frameworks to mandatory law.
Expert review openNo editor-accepted expert review yetDefinition
The public reporting by organisations of climate-related information — governance, strategy, risk management, metrics and targets, and greenhouse-gas emissions — following structured frameworks. Voluntary practice consolidated around the TCFD recommendations (2017), whose four-pillar architecture now underpins mandatory regimes built on the ISSB's IFRS S2 standard, the EU's CSRD/ESRS, and jurisdiction-specific laws such as California's SB 253/SB 261.

Overview
What it means
Climate disclosure travelled from niche ESG practice to financial-mainstream obligation in under a decade: the TCFD disbanded in 2023 having completed its mandate, with its content absorbed into IFRS S2; as of 2026, 36 jurisdictions have adopted or are finalising ISSB-based requirements, the UK, EU, Australia, Singapore, Japan, Brazil, Nigeria and others mandate climate reporting in some form, and the US federal SEC rule was withdrawn after litigation — leaving state law (California) as the US driver.
The field's live fault lines: financial materiality (ISSB) versus double materiality (CSRD), Scope 3 feasibility, assurance depth, and the transition from disclosing risk to demonstrating credible transition plans.
How it is used
Companies produce IFRS S2/CSRD-aligned reports with scenario analysis and Scope 1–3 inventories; investors and regulators consume disclosures for risk pricing and supervision; assurance providers verify emissions data; litigation and green-claims enforcement test disclosure accuracy.
Why it matters
Climate disclosure is the connective tissue between climate science and capital allocation — the mechanism meant to make climate risk visible, priced and managed across the economy.
Review
Public comments appear only after editor acceptance. Draft comments stay in the review queue.
Reviewers choose the definition or an overview paragraph, leave a comment or replacement, and attach evidence or a source link.
Editors compare reviewer cards side by side. AI may help find agreement, conflicts, unsupported claims and possible source issues.

Review board
Comment on a specific line. Each reviewer stays separate until an editor accepts a merged draft.
Each person comments on the definition or overview in their own draft card, with role, evidence and suggested wording kept together.
AI can compare comments against the current text, flag conflicting claims, surface missing evidence and identify where reviewers agree.
An editor merges compatible suggestions into a draft change, checks sources, records disagreements and decides what can be published.
