GLOSSARY GLOSSARY CDM Refers to conservation and demand management. CEA Refers to the Canadian Electricity Association. CO2e Often greenhouse gas emissions are calculated in terms of how much CO2 would be required to produce a similar warming effect. This is called the carbon dioxide equivalent (CO2 eq) value and is calculated by multiplying the amount of the gas by its associated global warming potential (GWP). Source: Environment Canada Emissions The release of greenhouse gases into the atmosphere over a specified period of time. Source: Environment Canada ERM Refers to Enterprise Risk Management Gigawatt-Hour (GWh) A standard unit for measuring electrical energy produced or consumed over time. One GWh is equal to one million kilowatt-hours. Global Reporting Initiative (GRI) An international not-for-profit organization that promotes the use of sustainability reporting as a way for organizations to become more sustainable and contribute to sustainable development. Its framework is a reporting system that provides metrics and methods for measuring and reporting sustainability-related impacts and performance. Source: Global Reporting Initiative Greenhouse Gas (GHG) Gaseous constituents of the atmosphere, both natural and anthropogenic, that absorb and emit radiation at specific wavelengths within the spectrum of infrared radiation emitted by the earth’s surface, the atmosphere and clouds. This property causes the greenhouse effect. Water vapour (H2O), carbon dioxide (CO2), nitrous oxide (N2O), methane (CH4) and ozone (O3) are the primary greenhouse gases in the earth’s atmosphere. Moreover, there are a number of entirely human-made greenhouse gases in the atmosphere, such as sulphur hexafluoride (SF6), hydrofluorocarbons (HFCs), and perfluorocarbons (PFCs).

Source: Environment Canada Greenhouse Gas Protocol Developed by World Resources Institute and World Business Council on Sustainable Development to set the global standard for how to measure, manage, and report greenhouse gas emissions. Source: Greenhouse Gas Protocol GRI Refers to Global Reporting Initiative. Source: Global Reporting Initiative GRI Aspect The word aspect refers to the list of subjects covered by the GRI guidelines. Source: GRI Implementation Manual GRI Aspect Boundary Refers to the description of where impacts occur for each material aspect and includes impacts within and outside of the organization. Aspect boundaries vary based on the aspects reported. Source: GRI Implementation Manual GRI General Standard Disclosures Offer a description of the organization and reporting process. Source: GRI Implementation Manual GRI Specific Standard Disclosures Offer information about the organization’s management and performance related to material Aspects.
