Grade summary

Mitsubishi produces seven SIN List substances, of which two are officially recognised as chemicals of high concern by the EU. The company has a method in place to screen and assess the sustainability of its products and includes intrinsic hazards of ingredients in the screening process. It does not, however, have a phase-out strategy for hazardous substances. The Tokyo-based company is a member of Responsible Care but has, over the last ten years, been involved in a couple of controversies regarding data manipulation.

Opportunities for improvement

  1. Add transparency to the hazardous product portfolio. We can only rank less than a quarter of Mitsubishi’s overall production since the rest takes place outside the EU and US. For other regions there are no reliable and publicly available sources for identifying producers of hazardous chemicals. Informing ChemSec of hazardous chemical production outside the EU and US could help raise the company score.
  2. One of Mitsubishi’s sustainability goals is to “become an entity that is friendly to both people and the planet”, and states that the company is “knowledgeable about chemical hazards of products ingredients”. To be knowledgeable is a good first step. The next step should be to act on this knowledge and not allow hazardous ingredients into newly developed products.
  3. Another related aim of Mitsubishi is to “supply environmentally-friendly products and services”. We encourage Mitsubishi to market these products publicly.

In 2010, it was also revealed that the Japanese company had manipulated wastewater data. As a result of the investigation, several more wastewater data manipulation cases were found.
