Methodology

ChemScore is an initiative from NGO ChemSec that aims to capture and rank the world’s largest chemical companies’ efforts to reduce their production of toxic chemicals and boost investments in safer, greener alternatives.

The 50 largest global stock exchange listed chemical companies based on their 2020 revenue are ranked in four categories.

  1. Product Portfolio: How many toxic chemicals are in each company’s product portfolio?
  2. Development of Safer Chemicals: How much effort goes into research & development?
  3. Management & Transparency: How progressive is the chemicals management and how much information is made public?
  4. Lack of Controversies: The number of controversies and scandals that the company has been involved in during the last ten years.

The points scored in each of these categories are then totalled to give an overall score, presented in the form of a letter grade. Read more about the categories in the menu to the left.
