Methodology

ChemScore is a brand new 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 35 largest global stock exchange listed chemical companies based on their 2018 revenue are ranked in four categories.

  1. Hazardous Product Portfolio
  2. Development of Safer Chemicals
  3. Management & Transparency
  4. Controversies

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, or download the top scorer’s report card here for a comprehensive look at the methodology.
