Companies today face growing pressure to report on their environmental, social, and governance practices. Understanding ESG reporting requirements is no longer optional—it’s essential for staying compliant and maintaining stakeholder trust.
This guide breaks down six key ESG reporting requirements that companies worldwide need to know.
Why ESG Reporting Requirements Matter
Investors, regulators, employees, and customers want transparency. They want to know how companies impact the world beyond just making money.
Ignoring these ESG reporting requirements creates serious risks:
- Regulatory penalties
- Damaged reputation
- Reduced access to capital
- Lost investor confidence
Let’s explore the major frameworks companies must navigate.
1. TCFD: Climate Risk Reporting
The Task Force on Climate-related Financial Disclosures (TCFD) helps companies report climate risks and opportunities. This framework shows investors how climate change affects business performance.
Many regions now require TCFD reporting, making it a foundation of modern ESG disclosure.
Governance and Oversight
Companies must show who manages climate issues:
- Which board members oversee climate risks
- How often the board discusses these issues
- How management identifies and handles climate risks
This starts at the top of the organization.
Strategy and Impact
Reports must explain how climate affects business:
Identify Risks and Opportunities
Climate risks include:
- Policy changes and new regulations
- Market shifts toward clean energy
- Extreme weather damaging facilities
- Rising sea levels affecting operations
Opportunities include:
- More efficient resource use
- New sustainable products
- Stronger resilience
Scenario Analysis
Companies should model different climate futures. This shows whether their strategy works if global temperatures rise by 2°C or less.
Risk Management
Companies must explain how they identify, assess, and manage climate risks alongside other business risks.
Detail your mitigation strategies:
- Investing in renewable energy
- Building supply chain resilience
- Adopting carbon reduction technologies
Metrics and Targets
Report specific numbers:
- Scope 1 emissions: Direct emissions from owned sources
- Scope 2 emissions: Indirect emissions from purchased energy
- Scope 3 emissions: Emissions from your value chain (if material)
Include water usage, energy consumption, and other relevant metrics. Set measurable targets with baseline years and progress updates.
2. GRI: Comprehensive Sustainability Framework
The Global Reporting Initiative (GRI) Standards provide a broad sustainability reporting standard used worldwide which defines ESG reporting requirements. Unlike TCFD’s climate focus, GRI covers economic, environmental, and social impacts.
Universal Standards
Three core standards apply to all companies:
GRI 101: Foundation Defines reporting principles and how to select material topics.
GRI 102: General Disclosures Requires information on:
- Company size and location
- Governance structure
- Stakeholder engagement
- Ethical practices
GRI 103: Management Approach Explains how you manage each material topic through policies and actions.
Topic-Specific Standards
GRI offers detailed standards in three areas:
Economic Standards (200 series) Cover economic performance, market presence, and anti-corruption practices.
Environmental Standards (300 series) Address energy, water, emissions, waste, and biodiversity. For example, GRI 305 requires detailed greenhouse gas reporting across all scopes.
Social Standards (400 series) Focus on human rights, labor practices, diversity, and community impacts. GRI 403 covers occupational health and safety, including injury rates and worker participation.
Materiality Assessment
GRI requires identifying your most significant impacts:
- Engage stakeholders to understand their concerns
- Identify actual and potential impacts across your value chain
- Prioritize topics based on severity and stakeholder importance
This ensures your report focuses on what truly matters.
3. SASB: Industry-Specific Standards
The Sustainability Accounting Standards Board (SASB) provides industry-specific ESG reporting requirements. While GRI looks at your impact on the world, SASB focuses on how sustainability issues affect your financial performance.
This makes SASB particularly valuable for investors.
Industry Focus
SASB created 77 industry-specific standards across 11 sectors. What matters for a technology company differs greatly from what matters for mining.
Steps to use SASB:
- Identify your industry standard
- Report on the specific metrics for your sector
- Focus on financially material issues
For example:
- Software companies report on data privacy and employee safety
- Steel producers report on air emissions and water consumption
Financial Materiality
SASB focuses on sustainability issues likely to affect financial performance. This ensures reported information directly helps investment decisions.
Connect ESG factors to:
- Revenue and expenses
- Assets and liabilities
- Cost of capital
For instance, carbon regulations could significantly impact costs for energy-intensive industries.
Quantitative and Qualitative Data
SASB requires both numbers and explanations:
Quantitative metrics provide measurable data:
- GHG emissions
- Water intensity
- Employee turnover
- Diversity percentages
Qualitative disclosures explain:
- Management approach
- Policies and programs
- Ongoing improvement efforts
4. CSRD: EU’s Expanded Requirements
The Corporate Sustainability Reporting Directive (CSRD) represents a major expansion of mandatory ESG disclosure in the European Union. It replaces the older Non-Financial Reporting Directive with much broader requirements.
This affects many companies—both inside and outside the EU.
Who Must Comply
The CSRD covers:
Large Companies Those meeting at least two criteria:
- Over 250 employees
- €40 million net turnover
- €20 million balance sheet total
Listed SMEs Small and medium companies listed on EU markets (with proportionate standards).
Non-EU Companies Those with significant EU operations generating over €150 million in EU turnover.
European Sustainability Reporting Standards
Companies must report using the European Sustainability Reporting Standards (ESRS):
Double Materiality Report on both:
- Your impact on society and environment (impact materiality)
- How sustainability issues affect your finances (financial materiality)
Comprehensive Topics Coverage includes:
- Climate change and emissions
- Pollution and water resources
- Biodiversity and ecosystems
- Resource use and circular economy
- Workforce and labor practices
- Community impacts
- Business conduct and anti-corruption
Assurance and Digital Format
The CSRD introduces important new ESG reporting requirements:
Mandatory Assurance Independent auditors must verify your sustainability data, starting with limited assurance and moving toward reasonable assurance over time.
Digital Reporting Reports must use machine-readable XBRL format. This makes data easier to extract and compare.
5. SEC Climate Rules: US Requirements
The Securities and Exchange Commission proposed climate disclosure rules for US-listed companies. While still being finalized, these rules signal a major shift in American regulatory expectations.
These ESG reporting requirements follow TCFD principles and aim to standardize climate disclosures for investors.
Who’s Affected
The proposed rules apply to all US publicly traded companies, making climate disclosure mandatory in annual reports and registration statements.
Climate Risks and Opportunities
Companies must disclose:
Risk Management
- How you identify climate risks
- How you assess potential impacts
- How climate fits into overall risk management
Business Impact
- How climate affects your strategy
- Changes to products and services
- Supply chain implications
- Research and development priorities
- Capital allocation decisions
Emissions Reporting
This is the most discussed aspect of the proposed rules:
Scope 1 and 2 Emissions All companies must report direct emissions and emissions from purchased energy.
Scope 3 Emissions Required if material or if you’ve set public reduction targets that include Scope 3. Larger companies need attestation for Scope 1 and 2 emissions.
Financial Statement Impact
Companies must quantify climate’s financial effects:
- Spending on climate risk mitigation
- Costs of renewable energy investments
- Financial impacts of severe weather
- Asset write-offs from climate events
- Insurance recoveries
6. ISSB: Global Baseline Standards
The International Sustainability Standards Board (ISSB) aims to create global baseline standards for ESG disclosure. These standards build on TCFD and seek worldwide consistency.
Think of ISSB as creating a universal blueprint for sustainability reporting.
IFRS S1: General Requirements
This standard covers all sustainability-related financial information:
Four Core Areas
- Governance
- Strategy
- Risk management
- Metrics and targets
Financial Connection Strong links between sustainability disclosures and financial statements ensure integrated reporting.
IFRS S2: Climate Disclosures
This standard focuses specifically on climate, incorporating TCFD recommendations and SASB industry guidance:
Climate Risks and Opportunities Report material climate issues across short, medium, and long-term horizons.
Scenario Analysis Assess your strategy’s resilience under different climate futures, including at least one scenario limiting warming to 1.5°C or 2°C.
GHG Emissions Report Scope 1, 2, and 3 emissions following the Greenhouse Gas Protocol. Explain your calculation methods.
Global Harmonization
ISSB’s key goal is creating a global baseline that works everywhere:
- Core requirements adoptable worldwide
- Room for additional jurisdiction-specific rules
- Reduced reporting burden for international companies
- Better comparability for investors
The ISSB works with other standard-setters like GRI to ensure different frameworks work together smoothly.

Frequently Asked Questions
What are ESG reporting requirements?
ESG reporting requirements are rules and frameworks that guide how companies disclose their environmental, social, and governance practices. These include both mandatory regulations (like CSRD in the EU) and voluntary standards (like GRI and SASB) that help companies report transparently on sustainability performance.
Why are ESG reporting requirements becoming stricter?
ESG reporting requirements are tightening because investors, regulators, and stakeholders demand better transparency on corporate sustainability practices. Climate change, social inequality, and governance failures create real financial risks, making robust ESG disclosure essential for informed decision-making.
What’s the difference between various sustainability reporting standards?
Different sustainability reporting standards serve different purposes: TCFD focuses on climate financial risks, GRI covers broad sustainability impacts, SASB targets financially material issues by industry, CSRD mandates comprehensive EU disclosures, and ISSB aims for global baseline standards. Many companies use multiple frameworks together.
Which ESG reporting requirements are mandatory?
Mandatory ESG reporting requirements vary by location and company type. The CSRD is mandatory for large EU companies and certain non-EU companies with EU operations. Proposed SEC rules would mandate climate disclosure for US public companies. Other frameworks like GRI and SASB remain voluntary but widely adopted.
How can small companies approach ESG reporting requirements?
Small companies should start with materiality assessment to identify key issues, choose appropriate frameworks (GRI and SASB offer good starting points), focus on material topics rather than comprehensive coverage, build data collection processes gradually, and consider proportionate standards like those for SMEs under CSRD.
