ESG reporting is evolving from a niche sustainability exercise into a core business function. In 2026, organisations are expected not only to disclose environmental, social, and governance (ESG) data, but to demonstrate how these factors impact financial performance, risk exposure, and long-term value creation.
For investors, regulators, and stakeholders, ESG reporting is now a critical decision-making tool. For companies, it represents both a compliance obligation and a strategic opportunity.
This guide explains everything you need to know, from ESG frameworks and metrics to step-by-step reporting processes and emerging trends.
What is ESG Reporting?
ESG reporting is the structured disclosure of non-financial data related to a company’s environmental, social, and governance performance.
It provides stakeholders with insights into how an organisation manages:
- Environmental impact (e.g., carbon emissions, energy use, waste, circular economy etc.)
- Social responsibility (e.g., stakeholder engagement, social value creation, labour practices, diversity)
- Governance structures (e.g., board composition, ethics)
Unlike traditional financial reporting, ESG reporting focuses on long-term sustainability, risk management, and ethical operations.
More importantly, modern ESG reporting connects non-financial performance with financial outcomes, helping stakeholders assess resilience and future growth potential.
Why ESG Reporting Matters in 2026
Regulatory Pressure is Increasing
Governments and regulators are rapidly introducing mandatory ESG disclosure requirements. Frameworks such as the EU’s Corporate Sustainability Reporting Directive (CSRD), the UK’s Sustainability Disclosure Requirements (SDR), the Australian Securities and Investment Commission (ASIC) and many others are transforming ESG from voluntary to mandatory.
Companies that fail to comply face legal risks, reputational damage, and reduced market access.
Recent regulatory developments do not change the nature of impacts nor the responsibility of organizations to address them. Even in a less burdensome regulatory context, a well-designed qualitative approach enables organizations to maintain continuity, credibility, and robustness in their sustainability journey.
Investors Are Using ESG Data to Allocate Capital
Institutional investors increasingly rely on ESG reporting to evaluate companies. Strong ESG performance can:
- Improve access to capital
- Lower cost of financing
- Increase investor confidence
ESG is no longer a “nice-to-have”; it is a financial signal.
ESG is a Core Risk Management Tool
ESG reporting helps to demonstrate that organisations are effectively identifying and managing risks such as:
- Climate change and environmental disruption
- Adverse impacts on the environment
- Waste management and circular economy
- Supply chain instability
- Governance failures and compliance breaches
By integrating ESG into reporting, companies gain a clearer view of both operational and strategic risks.
ESG Reporting Frameworks Explained
One of the biggest challenges in ESG reporting is navigating multiple frameworks. Each serves a different purpose.
Key ESG Frameworks
GRI (Global Reporting Initiative)
Focuses on a company’s impact on the environment and society. It is widely used for broad sustainability reporting.
SASB (Sustainability Accounting Standards Board)
Emphasises financially material ESG factors relevant to investors.
TCFD (Task Force on Climate-related Financial Disclosures)
Focuses specifically on climate-related risks and financial implications.
ISSB (International Sustainability Standards Board)
Aims to standardise ESG reporting globally and align sustainability disclosures with financial reporting.

ESG Metrics That Actually Matter
Not all ESG metrics provide equal value. High-quality ESG reporting focuses on material, decision-useful metrics.
Environmental Metrics
- Scope 1, 2, and 3 carbon emissions
- Energy consumption and intensity
- Water usage and waste management
- Emissions to land, air and water
- Life Cycle Analysis and Environmental Product Declarations
Social Metrics
- Employee turnover and retention
- Employee satisfaction
- Diversity, equity, and inclusion (DEI) metrics
- Local procurement and employment
- Social value creation
- Health and safety incident rates
Governance Metrics
- Board independence and diversity
- Executive compensation linked to ESG goals
- Anti-corruption and ethics policies
The key is to prioritise material metrics, those that significantly impact business performance and stakeholder decisions.
Metrics measured in isolation are of little use. Organisations need to establish their long and short term goals, baseline metrics and SMART targets. The metrics can then be used to gauge performance against targets and prompt corrective action if needed.
How to Create an ESG Report (Step-by-Step)
A structured approach is essential for effective ESG reporting.
Step 1: Identify Material ESG Issues
Determine which ESG topics are most relevant to your business and stakeholders. This often involves a double materiality assessment, considering both financial impact and societal impact.
Step 2: Map Stakeholders
Identify key stakeholders, including:
- Investors
- Regulators
- Customers
- Employees
Understanding stakeholder expectations ensures your ESG report is relevant and credible.
Step 3: Collect ESG Data
ESG data is often fragmented across departments such as finance, HR, operations, and procurement/supply chain.
Key challenges include:
- Data inconsistency
- Manual processes
- Lack of standardisation
- Limited resources
- Resistance from a multi-tiered supply chain to disclose data that may be sensitive
Implementing centralised data systems can help, but there is no easy solution. Data collection is challenging and will require extensive internal and supplier engagement.
Step 4: Select Reporting Frameworks
Choose frameworks that align with your objectives. Here are some examples of frameworks you may select:
- GRI for broad sustainability
- TCFD for climate risk
- SASB for investor relevance
Many organisations use multiple frameworks simultaneously.
Step 5: Validate and Assure Data
Each sustainability requirement should be verifiable via an evaluation procedure. When choosing an appropriate evaluation procedure, organizations should take into account the following factors:
- the materiality of the issue/requirement to the organization;
- the risks of non-conformity with the sustainability criteria;
- the cost of the evaluation procedure;
- The availability of technical infrastructure to support the evaluation procedure.
- the competence of the evaluator;
- The credibility of any external body or organization that is involved.
Evaluation procedures involve activities such as the review of documentation, testing, inspections, audits, certification, management systems, assessment, sustainability claims, labels and declarations, or a combination of them.
These activities can be carried out by the organisation or supplier (first-party), the purchasing organisation or an external body on its behalf (second-party), or an independent external body or organisation (third-party). When defining the evaluation procedure for each requirement, the organization should establish what activities should be carried out and by whom.
ISO standards that address conformity assessment should be used where relevant when establishing evaluation procedures. When choosing an evaluation procedure, the organization should balance cost in connection with the desired level of assurance. Cost can differ between evaluation procedures. The organization should also consider who bears the cost, taking into account the context of the supplier (e.g. size, location).
The organization should consider the level of assurance offered by each type of evaluation procedure. In general terms, certification schemes typically engender higher levels of confidence with limited effort for the purchasing organization.
The organization should also determine whether the technical infrastructure involved in the evaluation procedure is competent and complies with relevant applicable standards and guides.
When an external body is used, the organization should consider whether it is operating in accordance with relevant standards (e.g. ISO/IEC 17020, ISO/IEC 17021, ISO/IEC 17025, ISO/IEC 17024 and ISO/IEC 17065.)
Accreditation is a means of assessing, in the public interest, the technical competence and integrity of organizations offering evaluation services. Organizations might wish to consider the additional assurance that might be gained by using an accredited evaluation body.
Step 6: Publish and Improve Continuously
ESG reporting should not be a one-time activity. Leading organisations continuously refine their reporting processes and improve performance year over year.
Common ESG Reporting Challenges
Lack of Standardisation
The presence of multiple frameworks creates inconsistency and confusion. It is important to spend time with stakeholders to establish a framework that reflects the organisation’s material impacts.
Data Quality Issues
Many organisations rely on manual data collection, leading to inaccuracies and inefficiencies. It is important to establish a clear framework of meaningful data requirements before rushing into automating the collection of data that has no value. Investment in some automation may then have value.
Greenwashing Risks
“Greenwashing” is defined as “behaviour or activities that make people believe that a company is doing more to protect the environment than it really is”. Overstating ESG performance can damage credibility and lead to regulatory scrutiny. Use of effective verification techniques can help to mitigate these risks.
Resource Constraints
Smaller organisations often lack the expertise and tools needed for effective ESG reporting. VSME, the EU voluntary standard for SMEs, is designed to facilitate essential dialogue along the value chain but does not provide tools for quantitative reporting. Collaboration with similar organisations can help, along with accessing free training and tools.
ESG Reporting Best Practices
To produce high-quality ESG reports:
- Focus on material issues rather than reporting everything
- Clearly define goals, targets, indicators, and metrics before rushing into data collection
- Align ESG reporting with financial disclosures
- Use consistent methodologies across reporting periods
- Invest in ESG data systems and automation
- Ensure transparency and auditability
Best-in-class ESG reporting is clear, consistent, and decision-focused.
ESG Reporting Examples
Example 1: Integrated Reporting Approach
Some companies integrate ESG data directly into annual financial reports, providing a unified view of performance.
Example 2: Climate-Focused Reporting
Organisations in high-impact industries prioritise climate disclosures aligned with TCFD recommendations.
Example 3: Supply Chain Transparency
Companies with complex supply chains emphasise supplier audits and ethical sourcing metrics.
Real-world examples demonstrate how ESG reporting can be tailored to industry-specific risks and priorities.
The Future of ESG Reporting
ESG reporting is rapidly evolving. Key trends shaping the future include:
Standardisation Through ISSB
Global standards are slowly converging, reducing complexity and improving comparability over time.
Technology-Driven Reporting
AI and data platforms are emerging with the potential to enable:
- Real-time ESG monitoring
- Automated data collection
- Advanced analytics
Integration with Financial Reporting
ESG and financial disclosures are becoming increasingly interconnected, reflecting their combined impact on business performance.
Increased Regulatory Oversight
Some governments are tightening ESG requirements, making accurate reporting essential. Corporate ESG reporting must increasingly address what happens outside a company’s direct boundaries. Current economic and environmental dynamics show that a substantial share of value – and potential vulnerabilities – is generated through relationships with suppliers, partners, customers, and other actors involved in the production and distribution of goods and services.
