The green house effect has no territorial boundaries. Our stratosphere is shared among many countries and oceans without regard for nationalities and politics. The University is committed to meeting phase outs of ozone depleting substances (ODS) and reductions in green house gas (GHG) emissions.
Environment Canada classifes several compounds as ODSs:
- Chlorofluorocarbons (CFC)
- Carbon Tetrachloride (CTC)
- Hydrobromofluorocarbons (HBFC)
- Hydrochlorofluorocarbons (HCFC)
- Methyl Bromide
The stage for phase out of ODS was set by the Montreal Protocol on Substances that Deplete the Ozone Layer in 1987. The import, use and disposal of these compounds is severely restricted.
The University maintains an inventory of these substances and is actively participating to reduce inventories to meet required targets.
Visit the Ontario Ministry of the Environment for more information on ozone and air emissions.
Air emissions that contribute to the GHG effect are regulated. The NPRI reporting system requires the University to report GHG emissions to both Environment Canada and the Ontario Ministry of Environment.
Currently, SOx, NOx, CO, and particulates are reportable to Environment Canada. HFC134a, NOx, and SOx and solvents >3000 kg discharged to the atmosphere are reportable to MOE.
