ESG Score Meaning: Breaking Down The Calculation

ESG (Environmental, Social, and Governance) scoring is becoming increasingly crucial for businesses today. This is primarily due to a shift in investor behavior as they place more emphasis on sustainable and ethical business practices. A study by the Global Sustainable Investment Alliance (GSIA) found that sustainable investing assets reached $35.3 trillion globally in 2020, making up 36% of all professionally managed assets in the five major markets—a percentage that keeps growing, highlighting the increasing importance investors are placing on companies with strong ESG scores. 

It’s clear that ESG scoring has moved beyond being just a trend and is now considered an essential factor in assessing a company’s overall value and long-term viability. Today, we’re taking a deep-dive into how ESG scores are calculated and interpreted and what impact this can have on your business.

Understanding ESG Components

ESG scores are used to evaluate a company’s sustainability performance and business ethics. These scores are calculated based on a variety of factors related to a company’s environmental impact, social responsibility, and corporate governance practices:

  • Environmental criteria include a company’s energy use, carbon emissions and other pollution, waste management, water usage, and other climate change impacts.
  • Social criteria may include employee relations and labor practices, human rights, community engagement, diversity and inclusion policies, product safety, and data protection and privacy. 
  • Governance criteria include executive compensation, board diversity, shareholder rights, business ethics, and anti-corruption policies. 

The ESG Scoring Process

ESG scoring is a multi-step process that involves gathering, analyzing, and rating data relating to each of the three criteria detailed above. Third-party ESG rating agencies – including MSCI ESG Research, Sustainalytics, and Moody’s – oversee the ESG scoring process.Each agency uses its own complex algorithms and methodologies to evaluate companies, making the process more objective and less susceptible to bias. While there’s a general agreement on the ESG factors to consider, the weighting of these factors varies between rating agencies, which leads to differences in the ESG scores provided by different agencies for the same company.

To calculate ESG scores, the rating agency collects data from a wide range of sources, including company reports and disclosures, governmental databases, NGO publications, news outlets, and direct engagement with companies. The quality, consistency, and transparency of the data varies significantly depending on the company and the industry. This makes the process of data verification crucial to ensure the reliability of an organization’s ESG score.

Once the data is collected, it is then analyzed and converted into ratings. Each company is then assigned an overall ESG score, as well as scores for each of the three ESG categories. Although the scales used for ESG ratings vary between different rating agencies, most agencies use a scale that ranges from poor to excellent, which is represented either numerically or alphabetically, such as 1-100 or A-F. A higher rating signifies better ESG performance, indicating that a company is perceived to have lower ESG-related risks and is more likely to be practicing sustainable and ethical business. Companies with higher ESG scores may be seen as more sustainable and responsible, which can lead to increased investor interest, better reputations, and other benefits.

Investors and other stakeholders use ESG scores to evaluate a company’s sustainability performance and to make informed decisions about investing, partnering, or doing business with the company. 

An ESG Scoring Example

Let’s say a rating agency gives 50% weight to environmental factors, 30% to social factors, and 20% to governance factors. If a manufacturing company scores 80 out of 100 on environmental factors, 70 on social factors, and 90 on governance factors, the final ESG score would be calculated as follows: (0.5 * 80) + (0.3 * 70) + (0.2 * 90) = 76. While this is a simplification of a process that tends to be much more complex, it helps illustrate the basic approach to ESG score calculation.

The Importance of ESG Scores for Investors and Companies

Investors increasingly consider ESG scores as a critical factor in their decision-making process. High ESG scores often indicate that a company is more likely to be resilient to ESG-related risks, including regulatory changes, social unrest, or environmental disasters. Investors therefore tend to perceive these companies as less risky and more likely to provide sustainable returns. In contrast, low ESG scores can deter investment due to the associated risks.

ESG scores also have a direct impact on a company’s reputation. Companies with high ESG scores tend to be seen as responsible and sustainable, which can enhance their brand image, help attract customers, and improve stakeholder relations. This positive reputation can lead to financial benefits, including increased sales and access to capital. 

How to Improve Your ESG Score

Improving your company’s ESG score starts by implementing and demonstrating sustainable and ethical practices. One important step is reducing your environmental footprint by implementing more sustainable business practices. Responsible junk removal and recycling can contribute greatly to improving your ESG score.
