Sustainability and ethical practices are crucial factors that influence investment decisions and corporate reputations. Environmental, Social, and Governance (ESG) scores have emerged as crucial tools for evaluating a company’s dedication to these principles.  

By evaluating how organizations manage environmental responsibilities, social relationships, and governance structures, ESG scores provide stakeholders with insights into potential risks and opportunities. 

What is an ESG Score? 

An ESG score is a numerical indicator of a company’s Environmental, Social, and Governance performance. A higher score reflects stronger sustainability practices and risk management. These scores help investors assess a company’s dedication to responsible and ethical operations, supporting more informed investment choices. 

Why ESG Scores are Important 

ESG scores play a crucial role in helping companies enhance their governance and management. Here’s why they matter: 

  • Validation: ESG scores provide a precise and public measure of a company’s sustainability efforts, helping to validate its ESG initiatives. 
  • Peer Comparison: Companies and investors can use ESG scores to compare performance across similar organizations. 
  • Benchmarking: ESG scores enable industry-wide comparisons, indicating a company’s position within its sector. 
  • Progress Tracking: These scores provide a measurable way for companies to track and manage their ESG improvements over time. 
  • Investor Appeal: Investors rely on ESG scores to make responsible, sustainable investment choices. 
  • Risk Identification: Scores help highlight potential risks related to environmental, social, or governance issues. 

How ESG Scores are Calculated 

ESG scores in Indonesia and globally are based on information from company reports, government data, and news articles. Each rating agency uses methods often aligned with international standards, such as the Global Reporting Initiative (GRI), the Sustainability Accounting Standards Board (SASB), the Carbon Disclosure Project (CDP), and the UN Sustainable Development Goals (UN SDGs). 

Companies are assessed on factors such as carbon emissions, board diversity, and worker safety, which are combined to produce a final ESG score. There are two primary methods for calculating this score. 

  • Qualitative Method: This uses surveys and information provided by the company. However, it can miss important data if the company doesn’t share everything. 
  • Quantitative Method: This approach utilizes publicly available information, including official reports. It’s more consistent, but still depends on how much the company discloses. 

What is a Good ESG Score? 

A good ESG score reflects strong environmental, social, and governance performance. It indicates that a company manages sustainability risks effectively and aligns well with stakeholder expectations. ESG scores are often measured on a scale from 0 to 100 or using letter grades, with higher scores representing better ESG practices. Generally: 

  • Scores above 70 are considered strong, indicating that the company actively manages ESG risks and adheres to best practices. 
  • Scores between 50 and 70 indicate an average performance, suggesting that the company meets basic standards but may have areas for improvement. 
  • Scores below 50 indicate weaker performance and potential ESG-related risks. 

ESG Score vs. ESG Rating: What’s the Difference? 

Though often used interchangeably, ESG scores and ESG ratings have distinct meanings. Understanding their differences helps stakeholders better assess a company’s sustainability profile. 

What is an ESG Score and Why Does It Matter for Business

In short, an ESG score measures performance, while an ESG rating assesses risk. Both are valuable tools, but serve different decision-making needs. Companies in Indonesia aiming for better transparency and investor trust often strive to optimize both metrics. 

How to Improve Your Company’s ESG Score 

Enhancing your ESG (Environmental, Social, and Governance) score requires a strategic and comprehensive approach. Here are the steps companies can take to improve their ESG performance: 

Integrate ESG into Business Strategy 

Integrating ESG into the core business strategy ensures that sustainability goals align with corporate objectives. This integration enables more informed decision-making and demonstrates a commitment to long-term value creation. 

Conduct a Materiality Assessment 

Identify and prioritize ESG issues most relevant to your business and stakeholders. A materiality assessment helps focus efforts on areas with the most significant impact and significance. 

Align with Global and Regulatory Frameworks 

Adopt recognized ESG reporting standards such as the Global Reporting Initiative (GRI), Sustainability Accounting Standards Board (SASB), and the UN Sustainable Development Goals (SDGs). Compliance with these frameworks enhances transparency and comparability. 

Enhance ESG Data Collection and Reporting 

Implement robust systems for collecting, managing, and reporting ESG data. Accurate and timely disclosure of ESG metrics builds trust with stakeholders and can positively influence ESG ratings. 

Engage Stakeholders 

Involve employees, investors, customers, and communities in ESG initiatives. Stakeholder engagement fosters collaboration, accountability, and shared ownership of sustainability goals. 

Set Clear ESG Goals and Monitor Progress 

Establish specific, measurable ESG objectives and regularly track progress against these targets. Continuous monitoring enables timely adjustments and demonstrates a commitment to improvement. 

Seek ESG Advisory Services 

Engaging with ESG advisory firms can provide expert guidance on best practices, regulatory compliance, and practical strategies to enhance ESG performance. In Indonesia, ESG advisory services increasingly support businesses in navigating regulatory and investor expectations.
