I have already written a detailed article on what is ESG score and why it is important for the companies nowadays. But today, I will tell you how the score is being calculated and how to check ESG score by yourself.

What is ESG Score?

The ESG score of the company represents that how the company is responding in terms of environment, social, and governance while doing its business. These parameters are becoming more and more important as the whole world is now looking for sustainability alongside the business.

How ESG Score is calculated?

The ESG score is the outcome of many parameters on which the company’s performance is being evaluated. The percentile rank scores are simple to understand (available in both percentages and letter grades from D- to A+).

There are rating agencies like Refinitiv, MSCI, S&P Global, and so on. These rating agencies will collect the data from the public domain and after processing and comparing it with its peer companies, the final ESG score is derived.

I will discuss the methodology of Refinitiv’s ESG score. Refinitiv offers one of the most comprehensive ESG databases in the industry, covering over 70% of the global market cap, across more than 500 different ESG metrics, with a history dating back to 2002.

The ESG score covers 10 main themes like emissions, environmental product innovation, human rights, shareholders, and so on. The scores are based on the relative performance of ESG factors with the company’s sector (for environmental and social) and country of incorporation (for governance).

Below are the key factors through which the ESG score is calculated.

  • Unique ESG magnitude (materiality) weightings
  • Transparency stimulation
  • ESG controversies overlay
  • Industry and country benchmarks at the data point scoring
  • Percentile rank scoring methodology

Data Collection and Processing

There is a lot of work to be done for data collection and processing the collected data. The data is collected from various publicly available information sources to provide up-to-date information of the company. There are over 500 ESG measures for which the data are being processed. The database is updated on a continuous basis – aligned with corporate reporting patterns – and data is refreshed on products every week, including the recalculation of the ESG scores.

The data has been collected from number of sources and processed into a common format. The processed data is then plotted against the set parameters to derive the ESG score. All the parameters are divided into main 3 segments i.e. Environment, Social & Governance. The main score is then derive from the subset of these 500+ parameters.

ESG Score

captures and calculates over 500 company-level ESG measures, of which a subset of 186 (details in the ESG glossary, available on request) of the most comparable and material per industry, power the overall company assessment and scoring process.

These are grouped into 10 categories that reformulate the three
pillar scores and the final ESG score, which is a reflection of the company’s ESG performance, commitment and effectiveness based on publicly reported information.

The category scores are rolled up into three pillar scores – environmental, social and corporate governance. The ESG pillar score is a relative sum of the category weights, which vary per industry for the environmental and social categories.

For governance, the weights remain the same across all industries. The pillar weights are normalised to percentages ranging between 0 and 100.

ESG Controversy Score

ESGC scores provide a rounded and comprehensive scoring of a company’s ESG performance, based on the reported information pertaining to the ESG pillars, with the ESG controversies overlay captured from global media sources.

The main objective of this score is to discount the ESG performance score based on negative media stories. It does this by incorporating the impact of significant, material ESG controversies in the overall ESGC score.

When companies are involved in ESG controversies, the ESGC score is calculated as the weighted average of the ESG scores and ESG controversies score per fiscal period, with recent controversies reflected in the latest completed period.

When companies are not involved in ESG controversies, the ESGC score is equal to the ESG score.

The conversion from a percentile score to a letter grade is based on the logic in the table below.
