Sustainability frameworks are easier to understand when you separate five jobs: company reporting, financial product disclosure, activity classification, carbon pricing and voluntary climate claims.
Quick answer
Use this map when you are trying to work out whether a term is about reporting, finance, classification, carbon markets or claims. The frameworks overlap in practice, but they do not all do the same job.

- Do no significant harm (DNSH)
- Minimum safeguards

These systems put a compliance cost on emissions or offsetting obligations in specific sectors and jurisdictions.

Credit quality and public claims
These standards sit around voluntary carbon credits, removal quality and what companies can credibly say.
Credit quality

Voluntary Carbon Markets Integrity Initiative (VCMI) Guidance on how companies should use carbon credits in public climate claims.Removal and quality

If you are reading a company report
Start with reporting frameworks
Use the main company reporting guides first. These explain what the company is disclosing, what audience the disclosure serves and whether the topic is financial risk, impact or both.
If you are reading a fund factsheet
Start with finance disclosure
Use sustainable finance disclosure rules, fund labels, holdings and fees together. A label can help, but the holdings, index rules and stewardship evidence still matter.
If you are checking a green bond
Start with classification and use of proceeds
Use the EU Taxonomy, EuGB Standard, green bond framework, external review, allocation report and impact report. The label is only useful if the evidence chain is clear.
If you are assessing a climate claim
Start with claims and credit quality
Use voluntary carbon market integrity guidance, Core Carbon Principles labels, claims guidance and carbon credit quality checks. The central question is not whether a credit exists. It is whether the credit supports the claim being made.
Common confusion points
Reporting law vs standards
The law and the standards
The Corporate Sustainability Reporting Directive is the European Union reporting law. The European Sustainability Reporting Standards are the standards companies use to report under it. If the law answers "who reports", the standards answer "what do they report".
European Union disclosure vs United Kingdom labels
European Union disclosure and United Kingdom labels
The Sustainable Finance Disclosure Regulation is a European Union sustainable finance disclosure regime. The Sustainability Disclosure Requirements regime is the United Kingdom sustainability disclosure and investment labelling system. The names sound similar, but they are not the same system.
Taxonomy vs green bond label
Classification and a bond label
The EU Taxonomy classifies sustainable economic activities. The EuGB Standard is a voluntary green bond label that uses taxonomy alignment as a core test.
Credit quality vs claims quality
Credit quality and claims quality
The Integrity Council for the Voluntary Carbon Market focuses on carbon credit quality through Core Carbon Principles labels. The Voluntary Carbon Markets Integrity Initiative focuses on how companies make claims when using carbon credits. Buyers often need both lenses.
Where to go next
If the map gives you the structure, the detailed guides explain the working parts. Start with the sustainability acronyms guide, then use the specialist guides on CSRD reporting, SFDR, EU Taxonomy, European green bonds, EU ETS and UK ETS, EU ETS2, CORSIA, ICVCM and CCP labels and VCMI claims.
