As indicated in the 2 2 2 Corporate Footprint section in this ESG Report, our global operations do not have Scope 1 (direct) emissions as our offices rely on electricity and steam for energy and heating, which are included under our Scope 2 (indirect) emissions. ** As indicated in the Corporate Footprint section in this ESG Report, due to constraints owing to lack of information for certain leased premises in Perth, Australia (1 employee) and Colorado, United States (4 employees), our reported data for electricity and steam (each Scope 2 emissions) and water and waste (each Scope 3 emissions) relate only to our Toronto and Barbados offices and covers 87.5% (35 of 40 employees) of our company. We grossed up our total corporate operational emissions and purchased offsets representing 125% of our grossed up emissions to provide for a buffer to ensure that all of our company’s corporate operational emissions were covered, including to account for certain minimal but unquantifiable emissions which some of our employees may periodically contribute to.
