What is ESG Reporting? An Inclusive Guide

Not long ago, companies were judged almost entirely by their financial statements. If the profits looked strong, investors and customers followed. But times have changed. In today’s interconnected world, money is no longer the only currency; trust is. And the language of that trust is ESG reporting.

Think of it like this: a balance sheet shows “how much” a business earns, while an ESG report shows “how” it earns it. One tells the story of profit, the other tells the story of purpose. And in a world where consumers prefer sustainable brands and investors chase long-term value, it’s often the second story that sets companies apart.

What Is ESG Reporting?

ESG reporting serves as a key tool for companies to show their broader impact beyond financial results. This disclosure framework helps organisations showcase their steadfast dedication to environmentally responsible business practices.

ESG reporting reveals environmental, social, and governance data that gives stakeholders more than just traditional financial metrics. Stakeholders can learn about a company's effects on society and the environment while they assess potential risks and opportunities. Companies use transparent reporting to prove they meet sustainability goals instead of just "greenwashing".

Why is ESG Reporting important?

ESG reporting brings real business benefits beyond just meeting requirements. Companies that use ESG principles see measurable improvements in many areas of their operations.

1. Risk Management

Think of ESG reporting as an early warning system. By tracking environmental impact, social responsibility, and governance practices, companies can identify vulnerabilities, whether it’s a supply chain disruption due to climate change or a reputational risk from poor labour practices.

2. Investor Confidence: Beyond Numbers

Investors today are not just scanning balance sheets, they’re scrutinising sustainability reports. ESG performance is increasingly tied to financial stability and growth. Studies show that companies with strong ESG practices tend to outperform peers in the long run, attracting more investment and lowering capital costs.

3. Regulatory Compliance: Staying Ahead of the Curve

Governments worldwide are no longer treating ESG as optional, as ESG reporting is quickly becoming a legal and strategic requirement.

For example, Tata Group companies (like Tata Steel and Tata Power) have been proactive in integrating ESG reporting, particularly around climate risks and renewable energy commitments, ensuring they stay ahead of compliance requirements.

4. Brand Reputation: Winning Hearts and Minds

For marketing and communication professionals, this means telling stories that go beyond features and benefits; it’s about connecting a brand’s purpose with its audience. A company that wears its ESG commitments on its sleeve is more likely to inspire loyalty, advocacy, and long-term growth.

Key Components of ESG Reporting

At its core, ESG reporting is about measuring impact beyond profits. It breaks down a company’s responsibilities into three pillars, Environmental, Social, and Governance (ESG), that together reflect how responsibly and sustainably a business operates.

1. Environmental metrics

Imagine walking into a boardroom where the first slide is not about revenue, but rather the company’s carbon footprint. That’s the reality today. Businesses are judged not only on financial performance but also on their environmental stewardship. 

For example, in water-stressed regions of India, companies like ITC practice water-positive operations and detailed waste recycling, turning compliance into a competitive advantage.

2. Social metrics

If environmental metrics are about the planet, social metrics are about people, employees, customers, and communities. Workplace culture and community relationships shape social performance indicators. 

These metrics show workforce diversity percentages, how employees participate, and gender pay equity ratios. 

For example, from education programs to healthcare drives, ESG reports showcase how businesses contribute to society. Reliance Foundation’s CSR initiatives are a good benchmark.

3. Governance metrics

Think of governance as the compass ensuring the “E” and “S” directions aren’t lost; it’s what keeps companies on course. Governance is the backbone; the “G” in ESG ensures that both environmental and social initiatives are credible and accountable.

Investors want to see diversity and independence in boards. For instance, HDFC Bank reports board gender diversity as part of governance disclosures.

What are the global frameworks for ESG Reporting?

1. RI (Global Reporting Initiative)

The GRI Standards are the most widely used framework for sustainability reporting. They provide comprehensive guidance on disclosing a company’s impact on climate, society, human rights, and governance practices. 

In India, Tata Steel has been a pioneer in adopting GRI Standards for its sustainability disclosures. Its reports detail carbon emissions, energy use, responsible mining practices, and community development programs, demonstrating how a traditional heavy industry player can align with global best practices. 

2. SASB (Sustainability Accounting Standards Board)

Unlike GRI, which provides a broad view, SASB Standards are industry-specific. They help organizations identify and report on ESG issues that are financially material to their sector.

In India, several IT firms such as Infosys and Wipro have started aligning their reporting with SASB, especially to cater to global investors who demand sector-specific insights. 

3. TCFD (Task Force on Climate-related Financial Disclosures)

The TCFD framework, established by the Financial Stability Board, focuses on how climate change poses risks and opportunities for business operations and strategy.

In 2018, Mahindra & Mahindra became the first Indian company to commit to the TCFD framework. 

4. CDP (Carbon Disclosure Project)

The CDP specializes in environmental disclosures, asking companies to report on carbon emissions, water security, and deforestation practices. 

The Benefits of ESG for the company

• Regulatory Compliance: Staying ahead of evolving regulations, such as SEBI’s BRSR in India or the EU Green Deal, shields companies from penalties and builds global competitiveness.
• Societal Development: ESG-driven companies contribute to larger goals, such as reducing carbon footprints, promoting diversity, or advancing community welfare.
• Stronger Reputation: Businesses that prioritise sustainability are rewarded with enhanced brand value and a positive corporate image, reinforcing their role as leaders in ethical growth.

Challenges

While ESG reporting is gaining momentum worldwide, the journey toward meaningful and transparent disclosures is not without challenges. Let’s look at the major hurdles in detail:

1. Data Gaps: Hard to Track Everything
 Many industries work with long supply chains, making it tough to check if every supplier follows fair labor or eco-friendly practices. For example, textile companies in India often struggle to track sustainability across all their vendors.

2. Standardization Issues: Too Many Frameworks
 There are multiple reporting standards like GRI, SASB, TCFD, and CDP. While they aim to improve transparency, their differences often confuse companies about which one to follow.

3. Greenwashing Risks: When Claims Don’t Match Reality
 Some firms exaggerate their sustainability efforts, such as highlighting small eco-projects while hiding carbon-heavy operations.

4. Resource Constraints: Tough for Small Businesses
 Big companies can afford dedicated ESG teams and advanced tools. Smaller firms, however, often lack money, expertise, or technology to track emissions or water use. This makes it harder for them to meet global reporting standards and stay competitive.

Best Practices to follow

1. Set Clear Priorities
   Focus on what matters most to your business and stakeholders.
2. Adopt Global Frameworks
   Use recognised standards like GRI, SASB, TCFD, or CDP to ensure consistency and credibility.
3. Use Technology for Accuracy
   Leverage AI and digital tools to track emissions, energy use, and supply chains with precision.
4. Be Transparent, Not Perfect
   Acknowledge challenges and share progress honestly to avoid greenwashing.
5. Integrate ESG into Strategy
    Embed ESG goals into financial and operational plans for long-term value.
6. Build Internal Expertise
   Train employees, create ESG committees, and foster a culture of accountability.
7. Engage Stakeholders
   Communicate regularly with employees, investors, and regulators to build trust.

Conclusion

In the words of Ban Ki-moon, former UN Secretary-General:

 “Sustainability is the pathway to the future we want for all.” 

Those who embrace ESG today will define the leadership of tomorrow. ESG reporting is more like a promise than a compliance. It shows that companies care about people, planet, and profit in equal measure. For businesses, it builds trust and long-term value for professionals, and it opens doors to meaningful careers. 

The future of business is defined by transparency, responsibility, and accountability. ESG reporting is central to this shift, ensuring companies stay competitive and credible. For professionals, mastering ESG is essential. The IIM Calcutta Corporate Sustainability Course offers the tools to lead in this evolving space.

“Because Numbers may tell the story of profit, but ESG tells the story of purpose.”
