ESG Scores: Definition, Use Cases, Importance, and How to Improve

What is an ESG Score?

ESG Score stands for Environmental, Social, and Governance score. It is a metric used to evaluate a company’s performance in three critical areas:

1. Environmental (E): Impact on the natural environment, such as carbon footprint, resource usage, and waste management.
2. Social (S): Relationships with employees, customers, and communities, focusing on diversity, labor practices, and community engagement.
3. Governance (G): Leadership, business ethics, and transparency in corporate decision-making.

These scores are typically calculated by specialized ESG rating agencies, such as MSCI, Sustainalytics, and S&P Global, based on publicly available data and company disclosures.

What are the different uses for ESG Scores?

1. Investment Decisions: Investors increasingly prioritize companies with strong ESG performance, as they are seen as more sustainable and less risky in the long term.
   1. Publicly traded companies:
      1. Morningstar/ Sustainalytics: offers detailed ESG risk ratings to help investors understand how environmental and social risks could impact a company’s valuation. The “low, medium, or high risk” scoring system identifies material ESG issues relevant to specific industries.
      2. Moody’s ESG Solutions (Vigeo Eiris): Provides ESG assessments integrated with credit risk analysis, helping fixed-income investors assess long-term risks.
         Institutional investors rely on these scores to build ESG-focused portfolios or screen out high-risk companies.
   2. Private Equity:
      1. Investors assess ESG scores to identify potential risks and opportunities in their portfolio companies. Firms with strong ESG performance are often seen as lower risk and better positioned for long-term success.
      2. Portfolio Management: Private equity firms use ESG scores to monitor and improve the sustainability practices of their investments, enhancing value creation.

      

   3. Sustainable Supply Chain Finance and “green loans”:
      1. ESG in Supply Chain Finance: Corporate buyers and financial institutions offering early invoice payment programs are now taking into account suppliers’ sustainability performance to provide more attractive financing terms in order to incentivise suppliers to improve on ESG.
      2. ESG-Linked Financing: Banks and other financial institutions are driving ESG performance while creating innovative ESG-linked products by integrating EcoVadis Ratings into their eligibility criteria and linking ESG performance to financing products.
      3. ESG Ratings for Private Debt: By offering an improved borrowing rate for clients who have a strong EcoVadis Rating, private debt managers are tracking and improving ESG performance across their portfolio of borrowers.
2. Sustainable Procurement and supply chain: Companies are increasingly relying on ESG scores and ratings to manage sustainability in their supply chains. The drivers and benefits include:
   1. Regulatory Compliance: Many countries are introducing regulations that require companies to report on ESG metrics.
   2. Brand Reputation: Companies with high ESG scores often enjoy better reputations, attracting customers, employees, and partners.
   3. Supply Chain Risk Management: ESG-focused companies are often better prepared to handle environmental, social, and governance risks, such as climate change, labor strikes, and scandals.
   4. Financial Performance: Research indicates that companies with high ESG scores often outperform their peers financially over time. See “Do ESG Efforts Create Value?”, a study showing the strong correlations of ESG performance with higher profitability and growth rates.

   

How Is an ESG Score Calculated?

Each rating agency has its own sustainability / ESG rating methodology, but the process generally includes:

1. Data Collection includes:
   1. Company-Provided Data: Firms submit detailed information, including policies, program documentation, reports, and records. This encompasses sustainability or CSR reports, environmental impact assessments, and governance structures.
   2. External Information Sources: Analysts review data from reputable sources such as news outlets, regulatory bodies, and NGOs. This includes monitoring reports from organizations like China Labor Watch and the U.S. Environmental Protection Agency (EPA)
   3. Certifications and Standards: Possession of certifications like ISO 14001 (environmental management), ISO 26000 (social responsibility), and Forest Stewardship Council (FSC) labels can positively influence ESG scores. These certifications indicate adherence to recognized sustainability standards
   4. Audit Reports: Third-party audit findings provide insights into a company’s compliance with ESG criteria. These audits assess the effectiveness of implemented policies and identify areas for improvement.

   

2. Assessment: Assessing the company’s policies, practices, and performance in ESG criteria.
3. Weighting and Scoring: Assigning weights to different ESG factors based on their relevance to the company or industry.
4. Final Score: Producing an overall ESG score or rating, often on a scale (e.g., 0–100 or letter grades like AAA to CCC).

Advanced ESG rating methodologies integrate both quantitative data (e.g., emission metrics, diversity statistics) and qualitative assessments (e.g., policy effectiveness, governance quality). They may also consider industry-specific factors and regional regulatory environments. The Global Reporting Initiative (GRI) provides standards to guide businesses in disclosing sustainability-related information, ensuring alignment with global expectations and regulatory frameworks.

ESG Scores as a Catalyst for Sustainable Growth

Environmental, Social, and Governance (ESG) scores are no longer just a metric for corporate responsibility—they have evolved into a critical factor for driving sustainable growth. Companies that prioritize ESG principles create long-term value for stakeholders, mitigate risks, and adapt to shifting global challenges. Here are the core levers of how ESG scores act as a catalyst for sustainable growth.
