The GHS addresses classification of chemicals by types of hazard and proposes harmonized hazard communication elements, including labels and safety data sheets. It aims at ensuring that information on physical hazards and toxicity from chemicals be available in order to enhance the protection of human health and the environment during the handling, transport and use of these chemicals. The GHS also provides a basis for harmonization of rules and regulations on chemicals at national, regional and worldwide level. Chemicals, through the different steps from their production to their handling, transport and use, are a real danger for human health and the environment. People of any ages, from children to elderly, using many different languages and alphabets, belonging to various social conditions, including illiterates, are daily confronted to dangerous products (chemicals, pesticides, etc.) To face this danger, and given the reality of the extensive global trade in chemicals and the need to develop national programs to ensure their safe use, transport and disposal, it was recognized that an internationally-harmonized approach to classification and labeling would provide the foundation for such programs. Once countries have consistent and appropriate information on the chemicals they import or produce in their own countries, the infrastructure to control chemical exposures and protect people and the environment can be established in a comprehensive manner. The new system, which was called "Globally Harmonized System of Classification and Labeling of Chemicals (GHS)", addresses classification of chemicals by types of hazard and proposes harmonized hazard communication elements, including labels and safety data sheets. It aims at ensuring that information on physical hazards and toxicity from chemicals be available in order to enhance the protection of human health and the environment during the handling, transport and use of these chemicals. The GHS also provides a basis for harmonization of rules and regulations on chemicals at national, regional and worldwide level, an important factor also for trade facilitation. Classification and labeling of environmentally hazardous substances An important part of the CLP Regulation is the hazard class of environmentally hazardous substances and mixtures - more precisely, that of substances and mixtures hazardous to the aquatic environment. There is already a parallel additional EU hazard class for substances hazardous to the ozone layer. The GHS will soon also contain the criteria for the classification and labelling of environmentally hazardous substances with terrestrial toxicity.

Here is the link to the purple book and what the new legislation will be guided by of Canada

The hazard class “hazardous to the aquatic environment” is subdivided into the following categories:

Subdivision of the hazard class “hazardous to the aquatic environment“ into one acute and four chronic categories The communication of the hazard arising from substances hazardous to the ozone layer is depicted here:

Hazard category of the hazard class "hazardous to the ozone layer“ In the context of the REACH Implementation Project 3.6 (RIP 3.6) guidelines are currently being developed for the application of the provisions of the new regulation on the classification, labeling and packaging of substances and mixtures.
