During the 44th Session of the Sub-Committee of Experts on the Globally Harmonized System of Classification and Labelling of Chemicals, Austria, the EU, Finland, Germany, and the UK proposed revising Chapter 4.2 by adding the new hazard category related to global warming listed in the annexes to the Montreal Protocol. If the proposal is approved, the new classifications would be Hazardous to the Atmospheric System, which encompass both:
- Hazardous to the ozone layer; and
- Hazardous by contributing to global warming.
