SEAL Organizational Impact Award – Methodology Discussion:

In our discussions with sustainability executives, we have consistently heard these understaffed departments are overburdened by ESG questionnaires and assessments. Of note, a European institutional investor we hosted at our office that was interested in SEAL’s perspective on ESG was quite surprised at the length, rigor, and scope inherent in the leading evaluations. We encourage you to review the methodology for the forthcoming 2024 CSA as evidence.     

Rather than create yet another assessment, SEAL Awards’ approach to this Top 50 2023 Organizational Impact Award is purely analytical and leverages existing ESG databases. Said another way, no company award entries were considered.

The CDP and Corporate Sustainability Assessment (CSA, now part of S&P Global) data sets were chosen based on their quality, rigor, and global coverage. 

For further perspectives on the strength of the CDP and CSA, we encourage you to read SustainAbility’s 2019 report Rate the Raters 2019: Expert Views on ESG Ratings.    

The SEAL Awards analysis used the “Climate Change” dimension of CDP’s 2023 A-List assessment, which represented a universe of 21,000 disclosing companies. While important to our environmental progress, the “Water Security” and “Forests” CDP dimensions were not considered due to smaller sample sizes. 

This CDP data was combined with the 2023 CSA / S&P Global ESG ratings, which covered over 9,400 companies.

The SEAL Awards analyzed the distribution of rankings for each CDP and CSA to determine a numerical equivalent score that captured an equal level of selectivity.     

CDP A-List “Climate Change” alphabetical scores were converted as follows:

  • “A” = 99.2 points 
  • “A-” = 96.4 points

The CSA tiers were converted as follows:

  • “Gold” = 99.5 points 
  • “Silver” = 98.4 points
  • “Bronze” = 97.1 points

From this combined data set, the
SEAL Awards ranked the 50 most sustainable companies in the world.

Consistent with SEAL’s organizational focus, our methodology reflects a 69% weighting on the environmental dimension. Importantly, the SEAL methodology does incorporate “Social” and “Governance” components, thereby elevating the holistic ESG performance required for award winners.
