Environmental, Social and Governance (ESG) has evolved from a voluntary sustainability idea into a core business and investment decision-making framework. Today, ESG influences financing, compliance, risk management, stakeholder trust, and long-term value creation.

1. 📜 Origin and History of ESG

The concept of ESG originated from socially responsible investing and later evolved into a structured corporate performance framework.

Key Milestones

• 1960s–1980s: Ethical investing began (avoid tobacco, weapons, apartheid-linked companies).

• 1990s: Sustainability and corporate responsibility gained traction.

• 2004: ESG formally introduced in report “Who Cares Wins” by the United Nations Global Compact with financial institutions.

• 2006: Launch of UN Principles for Responsible Investment — institutional investors began integrating ESG.

• 2015: Adoption of United Nations Sustainable Development Goals and Paris Agreement accelerated ESG globally.

• 2020 onward: ESG became mainstream — mandatory disclosures, ratings, and investor screening.

👉 ESG moved from ethical investing → sustainability reporting → mandatory governance framework

2. 🎯 Why ESG is Needed

Organizations adopt ESG for risk mitigation, compliance, and long-term value creation.

Key Drivers

• Climate change and environmental risks

• Investor pressure and ESG-linked financing

• Regulatory compliance requirements

• Supply chain expectations (global clients demand ESG)

• Energy consumption

• Renewable energy use

• Water consumption and recycling

• Waste generation & disposal

• Biodiversity impact

• Air emissions

• Climate risk management

• Circular economy initiatives

👥 Social (S)

Focus: People and stakeholders

Key Social Indicators

• Compliance framework

• Business ethics

• Data privacy & cybersecurity

• Transparency & disclosures

6. 📈 ESG Reporting Framework Structure

Most ESG frameworks follow this structure: 

ESG reporting frameworks generally follow a structured approach covering Environmental, Social, and Governance pillars. The Environmental pillar focuses on climate change, resource consumption, emissions, and environmental management practices. Organizations typically disclose metrics such as greenhouse gas emissions, energy consumption, water usage, waste generation, renewable energy adoption, and biodiversity impacts.

The Social pillar focuses on employee welfare, human rights, stakeholder engagement, and community impact. Companies report indicators such as occupational health and safety performance, workforce diversity, employee training hours, labor practices, supply chain responsibility, customer satisfaction, and community development initiatives.

The Governance pillar focuses on corporate governance, ethical conduct, and compliance. This includes disclosure of board structure, independence of directors, anti-corruption policies, whistleblower mechanisms, risk management framework, business ethics, transparency practices, and regulatory compliance systems.

Together, these three pillars provide a comprehensive picture of an organization’s sustainability performance and responsible business practices.

7. ESG vs Sustainability vs CSR

ESG, sustainability, and Corporate Social Responsibility (CSR) are often used interchangeably, but they differ in scope and purpose.

ESG is a structured framework used to measure and evaluate a company's environmental, social, and governance performance using defined metrics. It is increasingly becoming mandatory for listed companies and is widely used by investors, lenders, and rating agencies for decision-making.

Sustainability is a broader concept that focuses on long-term environmental protection, social responsibility, and economic viability. It is more strategic and vision-oriented, guiding companies toward responsible growth and resource conservation. Sustainability initiatives are often voluntary and may not always be measured through defined indicators.

Corporate Social Responsibility (CSR) refers to a company's commitment to contribute to societal development, typically through community programs, education support, healthcare initiatives, and environmental conservation projects. In India, CSR spending is mandatory for eligible companies under the Companies Act, 2013. CSR is only one component of the broader ESG framework and primarily falls under the Social pillar.

In simple terms, sustainability is the overall goal, ESG is the measurement framework, and CSR is one of the implementation mechanisms focused mainly on social impact.
