Environmental, Social and Governance (ESG) has moved from being a specialised sustainability concept to an important part of modern business strategy. Companies are increasingly being evaluated not only on revenue, profitability and market share, but also on how they manage environmental risks, treat employees and communities, protect stakeholder interests, and maintain transparent and ethical governance.

Investors, customers, employees, regulators and business partners increasingly want to understand whether a company can create value responsibly and remain resilient over the long term.

ESG is particularly important because environmental and social issues can eventually become financial and operational issues. Climate-related disruptions can affect supply chains, poor labour practices can damage reputation, and weak governance can lead to regulatory penalties or loss of investor confidence. At the same time, effective ESG practices can create opportunities through resource efficiency, innovation, responsible sourcing, better employee engagement and access to capital.

The importance of ESG is also reflected in the rapid development of sustainability reporting standards. The IFRS Foundation says that 49 jurisdictions responding to its 2025 survey had introduced or planned sustainability-related disclosure requirements, while 47 had adopted, or planned to adopt or otherwise use, ISSB Standards.

In India, SEBI's Business Responsibility and Sustainability Reporting (BRSR) framework has made ESG reporting an increasingly important part of the listed-company landscape.

Why Is ESG Important for Businesses? Understanding Its Role in Sustainable Growth 

What Is ESG? Understanding the Meaning

ESG stands for Environmental, Social and Governance. It is a framework used to assess how an organisation manages sustainability-related risks, opportunities, responsibilities and impacts.

Rather than looking only at financial performance, ESG provides a broader perspective on how a company operates and how its activities affect the environment, employees, customers, communities, investors and other stakeholders.

According to Anthesis, ESG evaluates areas including sustainability, ethical impact and risk management, with the three pillars being interconnected rather than independent categories.

What Does ESG Stand For?

E – Environmental: How a company interacts with the natural environment.

S – Social: How a company treats people and manages relationships with employees, customers and communities.

G – Governance: How a company is directed, controlled and held accountable.

A strong ESG approach therefore asks a simple but important question: Can a business create long-term economic value while managing its environmental, social and governance responsibilities effectively?

The Three Pillars of ESG

1. Environmental: Managing the Impact on the Planet

The environmental component examines the relationship between a business and the natural environment.

Companies may be assessed on their greenhouse-gas emissions, energy consumption, water use, waste generation, pollution, resource efficiency, biodiversity impacts and exposure to climate-related risks. These issues vary significantly between industries.

For example, an energy company may face major questions around carbon emissions and the transition to cleaner energy, while a manufacturing company may need to focus on energy efficiency, waste, water consumption and pollution control.

Key Environmental ESG Factors

Some common environmental indicators include:

  • Greenhouse-gas emissions
  • Energy consumption and energy efficiency
  • Renewable-energy use
  • Water consumption and management
  • Waste generation and recycling
  • Air and water pollution
  • Biodiversity and ecosystem impacts
  • Climate-related risks
  • Sustainable resource use
  • Circular-economy initiatives

Environmental responsibility is no longer simply about improving a company's public image. Physical climate risks, resource scarcity, changing regulations and supply-chain disruptions can affect operating costs and business continuity.

2. Social: Putting People at the Centre

The social pillar focuses on how a business affects people.

This includes employees, customers, suppliers, local communities and other stakeholders. Companies are increasingly expected to demonstrate responsible labour practices, workplace safety, human-rights protections and fair treatment.

Key Social ESG Factors

Important social considerations can include:

  • Employee health and safety
  • Wages and working conditions
  • Diversity, equity and inclusion
  • Employee training and development
  • Human rights
  • Labour standards in supply chains
  • Customer privacy and data protection
  • Product safety and quality
  • Community development
  • Customer satisfaction
  • Responsible sourcing

A company may have excellent environmental credentials but still face significant ESG problems if it has unsafe workplaces, poor labour practices or weak customer protections.

Social performance can also influence recruitment and retention. Employees increasingly want to work for organisations whose values align with their expectations around fairness, inclusion, purpose and responsible business behaviour.

3. Governance: Building Responsible Leadership

Governance refers to the systems, structures and processes through which a company is managed and held accountable.

Good governance provides the foundation for credible ESG performance because it determines how decisions are made, risks are monitored and responsibilities are assigned.

Key Governance ESG Factors

Governance may include:

  • Board composition and independence
  • Executive remuneration
  • Business ethics
  • Anti-corruption measures
  • Risk management
  • Shareholder rights
  • Transparency
  • Regulatory compliance
  • Audit practices
  • Data governance
  • Cybersecurity oversight
  • Whistleblower mechanisms

Strong governance can help prevent misconduct and ensure that sustainability commitments are connected to actual business decisions rather than treated as separate corporate initiatives.

Why Is ESG Important for Businesses?

ESG matters because environmental, social and governance issues can directly or indirectly influence a company's financial performance, reputation, resilience and ability to grow.

Anthesis highlights several business reasons for ESG, including risk management, regulatory compliance, stakeholder expectations, sustainability, access to capital and operational improvement.

ESG Helps Businesses Identify and Manage Risks

Every business faces risks. Some are financial, while others originate from environmental, social or governance issues.

For example, a company dependent on water-intensive production could face operational risks from water scarcity. A manufacturer with poor labour standards in its supply chain could face reputational or legal problems. A company with weak internal controls could become vulnerable to fraud or corruption.

ESG encourages companies to identify these risks early and incorporate them into broader enterprise risk management.

ESG Can Improve Operational Efficiency

Sustainability initiatives can sometimes generate direct operational benefits.

Reducing energy consumption can lower electricity costs. Better waste management can reduce material losses. Efficient water use can lower operating expenses. Sustainable logistics can potentially reduce fuel consumption.

Therefore, ESG should not automatically be viewed as an additional cost. In many cases, it can encourage businesses to identify inefficient processes and develop more effective ways of working.

ESG Can Strengthen Brand Reputation

Reputation is a valuable business asset.

Companies that demonstrate responsible behaviour can strengthen relationships with customers, employees, communities and business partners. Conversely, environmental damage, labour controversies or governance failures can rapidly damage public trust.

However, companies must ensure that ESG claims are supported by measurable evidence. Exaggerated sustainability claims can create accusations of greenwashing, potentially undermining the credibility ESG efforts are intended to build.

ESG Can Influence Access to Capital

Investors increasingly consider sustainability-related risks and opportunities when evaluating businesses.

The global sustainable-investment landscape is becoming more structured around disclosure and comparable information. The Global Sustainable Investment Alliance's latest review said sustainable and responsible investment had moved from a niche practice towards a systemic consideration, although it also cautioned that progress remains insufficient relative to global sustainability challenges.

Better ESG information can therefore help investors understand risks that may not be immediately visible in traditional financial statements.

ESG and the Changing Regulatory Landscape

One of the most significant developments in ESG has been the emergence of sustainability-related disclosure requirements.

The International Sustainability Standards Board (ISSB) developed IFRS S1 and IFRS S2 to establish a global baseline for sustainability-related financial disclosures. The IFRS Foundation says the standards are intended to provide consistent and comparable information for capital markets.

The direction of travel is significant: governments and regulators in numerous jurisdictions are developing or considering approaches to sustainability reporting.

As of the IFRS Foundation's 2025 survey, 47 of the 49 responding jurisdictions had adopted, planned to adopt or otherwise use ISSB Standards, while 76% had declared an objective of full adoption.

ESG Is Becoming More Data-Driven

This development means companies increasingly need reliable ESG data.

Businesses may need to collect information covering emissions, energy, water, workforce indicators, supply chains, governance processes and other material sustainability factors.

Consequently, ESG is increasingly connected with:

  • Data management
  • Internal controls
  • Financial reporting
  • Risk management
  • Audit and assurance
  • Corporate strategy
  • Board oversight

ESG in India: Understanding BRSR

India has developed its own sustainability-reporting framework through SEBI's Business Responsibility and Sustainability Report (BRSR).

BRSR is applicable on a mandatory basis to the top 1,000 listed entities by market capitalisation. SEBI describes BRSR as a more quantitative and outcome-oriented framework compared with the earlier Business Responsibility Report.

SEBI also introduced BRSR Core, containing a selected group of key performance indicators intended to improve the reliability of ESG disclosures. The original framework prescribed a phased expansion from the top 150 listed entities in FY2023-24 towards the top 1,000 by FY2026-27.

In March 2025, SEBI introduced changes intended to facilitate ease of doing business, including additional time for companies and value-chain partners to establish measurement and reporting systems.

Why BRSR Matters to Indian Businesses

BRSR is important because it places greater emphasis on measurable sustainability information.

For Indian listed companies, ESG is therefore increasingly connected with regulatory reporting, investor communication and corporate governance.

It also means ESG considerations can extend beyond the company itself. Supply chains, vendors and other value-chain partners may become increasingly important when companies assess their overall sustainability performance.

What Is ESG Reporting?

ESG reporting is the process through which a company communicates relevant information about its environmental, social and governance performance, risks and opportunities.

A meaningful ESG report should provide reliable, relevant and comparable information rather than simply highlighting positive initiatives.

Anthesis notes that ESG reporting can include quantitative and qualitative information such as emissions, energy and water use on the environmental side; workforce and community information under social factors; and board composition, executive compensation and ethical conduct under governance.

Why ESG Reporting Matters

Effective reporting can help:

  • Investors evaluate sustainability-related risks
  • Regulators monitor compliance
  • Customers understand corporate practices
  • Employees assess employer values
  • Boards monitor performance
  • Businesses identify areas for improvement

The growing emphasis on comparable information is one reason international sustainability standards have become increasingly important.

Major ESG Reporting Frameworks and Standards

Businesses may encounter several ESG-related frameworks and standards.

Global Reporting Initiative (GRI)

GRI provides a widely used sustainability-reporting framework focused on an organisation's impacts on the economy, environment and people.

Sustainability Accounting Standards Board (SASB)

SASB developed industry-specific standards focused on sustainability issues that can be financially material to investors. Its standards have been incorporated into the broader work of the IFRS Foundation's sustainability reporting architecture.

International Sustainability Standards Board (ISSB)

ISSB operates under the IFRS Foundation and focuses on establishing a global baseline for sustainability-related financial disclosures.

IFRS S1 covers general sustainability-related financial information, while IFRS S2 focuses specifically on climate-related disclosures.

The IFRS Foundation continues to develop implementation guidance and monitor how jurisdictions use the standards. Its current jurisdictional profiles show that adoption and implementation are progressing across numerous markets.

Task Force on Climate-related Financial Disclosures

The TCFD recommendations played an important role in shaping climate-related reporting. The IFRS Foundation notes that the TCFD recommendations have been incorporated into the ISSB Standards.

European Sustainability Reporting Standards

The European Sustainability Reporting Standards (ESRS) support reporting under the EU's Corporate Sustainability Reporting Directive. They represent another major development in the standardisation of corporate sustainability information.

How Businesses Can Build an Effective ESG Strategy

ESG should ideally be integrated into the company's business strategy rather than treated as a separate public-relations exercise.

Anthesis recommends a structured approach that includes materiality, stakeholder engagement, goal setting, data collection, integration, transparency, reporting and continuous improvement.

Step 1: Identify Material ESG Issues

Not every ESG issue has the same relevance for every business.

A mining company, technology company, bank and food manufacturer will have very different ESG priorities.

Companies should identify the environmental, social and governance issues that have the greatest impact on their business and stakeholders.

Step 2: Engage Stakeholders

Businesses should understand the expectations of:

  • Investors
  • Employees
  • Customers
  • Suppliers
  • Communities
  • Regulators
  • Business partners

Stakeholder engagement can help companies identify risks and opportunities that may otherwise be overlooked.

Step 3: Set Measurable ESG Goals

Broad commitments such as "become more sustainable" are difficult to evaluate.

Companies should establish measurable targets, timelines and responsibilities.

Examples could include reducing energy intensity, improving workplace safety, increasing renewable-energy use, strengthening diversity or improving supply-chain traceability.

Step 4: Collect Reliable ESG Data

A strong ESG strategy requires good data.

Companies should establish clear processes for collecting, checking, storing and reporting ESG information.

Poor-quality data can undermine both internal decision-making and external reporting.

Step 5: Integrate ESG Into Business Decisions

ESG should be considered during:

  • Investment decisions
  • Product development
  • Procurement
  • Hiring
  • Supply-chain management
  • Risk assessment
  • Capital allocation
  • Mergers and acquisitions

This makes ESG part of the business rather than a standalone sustainability programme.

Step 6: Report Transparently

Companies should communicate both progress and challenges.

Transparent reporting can strengthen credibility because stakeholders are more likely to trust organisations that acknowledge areas requiring improvement rather than presenting an unrealistically perfect picture.

Step 7: Monitor and Improve

ESG is not a one-time project.

Climate risks, regulations, technologies, stakeholder expectations and market conditions continue to change. Businesses should therefore regularly review their ESG priorities and update their strategy.

Common ESG Challenges for Businesses

Despite its growing importance, implementing ESG can be challenging.

Lack of Reliable Data

Many businesses struggle to collect accurate information across multiple locations, suppliers and subsidiaries.

Different Reporting Requirements

Companies operating internationally may face different reporting requirements in different markets.

Cost of Implementation

Building ESG data systems, conducting assessments and obtaining assurance can require investment, particularly for smaller businesses.

Greenwashing Risk

Businesses may face criticism if their sustainability claims are not supported by measurable evidence.

Supply-Chain Complexity

A company's environmental and social impact can extend beyond its direct operations. Understanding suppliers' practices can therefore be difficult but increasingly important.

ESG Is More Than Environmental Sustainability

A common misconception is that ESG simply means "going green."

Environmental issues are certainly important, but ESG covers three interconnected areas.

A company that reduces carbon emissions while ignoring worker safety still has significant ESG weaknesses. Similarly, a company with strong employee policies but poor governance and corruption controls cannot claim comprehensive ESG performance.

The strength of ESG lies in considering environmental, social and governance factors together.

ESG, Sustainability and CSR: What Is the Difference?

These terms are related but not identical.

Sustainability is a broad concept concerning the long-term viability of economic, environmental and social systems.

CSR (Corporate Social Responsibility) generally refers to a company's responsibilities and voluntary activities toward society and communities.

ESG provides a structured framework for evaluating and measuring environmental, social and governance factors, particularly those relevant to business performance, risks, opportunities and stakeholders.

In practice, companies may use all three concepts within their broader responsible-business strategy.

What Does ESG Mean for Small and Medium Businesses?

ESG is not relevant only to large corporations.

Small and medium-sized businesses can also benefit from practical ESG initiatives.

For example, a smaller company can:

  • Reduce unnecessary energy consumption
  • Minimise waste
  • Improve workplace safety
  • Strengthen employee policies
  • Protect customer data
  • Improve supplier standards
  • Establish ethical business practices
  • Track relevant sustainability metrics

Smaller companies may not need the same reporting infrastructure as large listed corporations, but establishing good practices early can make it easier to respond to customer, investor and supply-chain expectations as the business grows.

The Future of ESG in Business

ESG is likely to become increasingly connected with mainstream corporate strategy.

The direction of international reporting standards suggests that sustainability information is becoming more structured and comparable. The IFRS Foundation's current work includes supporting jurisdictions implementing ISSB Standards and continuing research into areas such as nature-related risks and opportunities.

At the same time, businesses are likely to pay greater attention to:

  • Climate resilience
  • Biodiversity and nature
  • Supply-chain transparency
  • Responsible artificial intelligence
  • Data privacy
  • Workforce wellbeing
  • Cybersecurity
  • Circular economy
  • Sustainable finance
  • Transition planning

The next phase of ESG will therefore not simply be about producing sustainability reports. It will increasingly involve using sustainability information to make better business decisions.

Conclusion: Why ESG Matters for Long-Term Business Success

ESG has become an important framework for understanding how businesses manage environmental responsibilities, social relationships and governance practices. Its importance comes from the fact that these factors can influence operational resilience, reputation, regulatory compliance, stakeholder trust, investment decisions and long-term financial performance.

For businesses, the most effective ESG strategy is not simply to publish a sustainability report or adopt a few environmental initiatives. ESG needs to be integrated into strategy, risk management, operations, supply chains, governance and decision-making.

The regulatory environment is also evolving. Internationally, ISSB Standards are becoming an important foundation for sustainability-related financial disclosures, with numerous jurisdictions moving towards adoption or other forms of use. In India, SEBI's BRSR and BRSR Core frameworks are helping make ESG measurement and disclosure increasingly relevant for listed companies.

Ultimately, ESG should not be viewed merely as a compliance requirement or a trend. When implemented properly, it can help businesses identify risks earlier, improve efficiency, build stakeholder confidence, encourage innovation and prepare for a rapidly changing economic and environmental landscape.

A company that understands its environmental footprint, invests in its people and communities, and maintains strong governance is better positioned to build trust, resilience and sustainable long-term value.
