  • 1Some of this environmental data has been third-party verified. The verification covers sites participating in the European Union Eco-Management and Audit Scheme (EMAS).
  • 2Energy consumed within our organization includes non-renewable and renewable fuel, and the purchase of electricity, steam and heat. We do not include energy purchased for cooling and do not sell energy. We do not currently measure the energy consumed outside the organization. Energy consumption data is compiled through invoice or meter measurements from our sites and consolidated in a central database. Factors from the International Energy Agency, Energy Statistics Manual, were used to convert energy consumption volumes into GJ.
  • 3Other non-renewable fuels consumed within our operations include: gasoline, naptha, residual fuel oil, acetylene, LPG, and diesel.
  • 4Energy intensity relates to energy consumed within our organization, covering both renewable and non-renewable fuel as well as the electricity, steam and hot water purchased at our sites.
  • 5Some of this data has been third-party verified. The verification covers sites that qualify under the European Union Emission Trading Scheme (EU ETS) as well as those receiving external verification for GHG emissions under the Québec cap-and-trade system for GHG emission allowances (C&T system).
  • 6Some of this environmental data has been third-party verified. The verification covers sites participating in the European Union Eco-Management and Audit Scheme (EMAS).
  • 7We report GHG emissions based on an operational control consolidation approach. The scope 1 emission factors are compiled from the International Panel for Climate Change. The scope 2 emission factors are compiled from local utilities, provinces/states, and national inventories, where available. For both scope 1 and 2, we apply the International Panel for Climate Change (2007 Fourth Assessment Report) Global Warming Potentials to our calculations, which includes the following gases: carbon dioxide (CO2), Methane (CH4), Nitrous oxide (N2O), and Hydrofluorocarbons (HFCs). Scope 3 emissions are currently not included.
  • 8GHG intensity relates to scope 1 and 2 emissions only. It includes the following gases: CO2, CH4, N2O, and HFCs.
  • 9Ozone-Depleting Substances (ODS) are used in air conditioning units, freezers, refrigerants in our facilities, trains and aircraft. We calculate the GHG emissions using the amount of ODS associated to accidental leaks in equipments and then applying the relevant global warming potentials from the International Panel (2007 Fourth Assessment Report) covering hydro fluoro carbons.
  • 10We confirm our disposal methods through reports provided to us by our disposal contractors. Composted waste is included in our energy valorization numbers. We do not dispose any waste by deep well injection. We also do not have on-site storage.
  • 11Valorized waste refers to hazardous and non-hazardous waste, which has been redirected to a process that reuses, recycles, composts and combusts the waste into useful product or sources of energy. The number reported is the percentage of valorized waste as compared to our total waste generated (including both hazardous and non-hazardous waste).

* The scope of our reported environmental and energy data includes: buildings we own or lease long term and manage as the sole tenant, with more than 4,645 square meter (50,000 square feet) of conditioned space; sites having 150 employees or more; sites that are considered primary production/operation and service facilities; and joint ventures where we have operational control (where we own more than 50% of voting shares).
In some cases, the data does not always add up to the corresponding sub-totals and totals, which we did not round.
