Framework Overview
The ESG reporting landscape has four dominant frameworks, each serving different stakeholder needs. Understanding the differences — and overlaps — between GRI, SASB, TCFD, and CDP is critical for choosing the right reporting approach for your company.
Side-by-Side Comparison
| Aspect | GRI | SASB | TCFD | CDP |
|---|---|---|---|---|
| Primary audience | All stakeholders | Investors | Investors & regulators | Investors & customers |
| Focus | Broad sustainability impact | Financially material ESG | Climate risk | Environmental disclosure |
| Industry-specific | Sector standards available | Yes (77 industries) | No (universal) | Sector questionnaires |
| Mandatory anywhere | EU reference standard | SEC references | UK, EU, Japan, others | Voluntary (widely expected) |
| Best for | Comprehensive reporting | Investor meetings | Climate risk disclosure | Environmental scores |
GRI — Global Reporting Initiative
GRI is the world's most widely used sustainability reporting framework. It takes a multi-stakeholder approach, covering the full range of environmental, social, and governance topics. GRI is structured around Universal Standards (applicable to all), Sector Standards, and Topic Standards.
Best for companies that need to communicate broadly with employees, communities, regulators, and investors. Learn more about GRI reporting with GreenScore.
SASB — Sustainability Accounting Standards Board
SASB provides industry-specific ESG disclosure standards designed for investor decision-making. With 77 industry standards, SASB focuses on the ESG topics most likely to impact a company's financial performance — making it the preferred framework for institutional investors.

TCFD — Task Force on Climate-related Financial Disclosures
TCFD focuses specifically on climate-related financial risk disclosure. It's structured around four pillars: Governance, Strategy, Risk Management, and Metrics & Targets. TCFD recommendations are increasingly being embedded into regulatory requirements worldwide.
