The science behind ESG Score

One score that says all

How can a multi-facetted issue, the sustainability of a product, be expressed in a simple numeric value? This is the question everyone asks. Here comes the long and detailed answer.

Each week, we publish updated leaderboards in which products are sorted by sustainability based on their ESG Score, which is calculated with category-specific scoring criteria applied to product-specific sustainability data.

How we determine the ESG Score

1

Attribute points to products

Points are attributed by applying the category specific scoring criteria to the products' sustainability data profiles.

Attribute points to the products
2

Identify the highest point sum

For each category the highest achieved point sum among the products is identified.

3

Derive the ESG Score

The ESG Score for each product is derived from the percentage of the product's point sum compared to the highest point sum of the category.

The product's point sum equals to 27% of the highest point sum
The product's point sum equals to 56% of the highest point sum
The product's point sum equals to 100% of the highest point sum

Please note: The color code of our labeling shows the top third ESG Scores as green, the middle third as yellow, and the lowest third as red.

Impartiality and Independence

  • ESG Score does not realize any income from business with manufacturers. ESG Score thus, does not have any conflicts of interest in regard to companies whose products it is assessing.
  • Our main revenue comes from buyers who pay for getting fact-based, independent scorings
  • Additional revenues result from fees for distributing certifier data to retailers and procurement systems plus from fees that retailers and procurement systems pay for ESG data.

ESG Score100

ESG Score 100 and rank 1 can result from being the least bad product without being absolutely sustainable. This best-in-class approach has been chosen after intense discussions with independent experts and leading institutes.
