Countries around the world are aiming to reduce carbon footprint to halt climate change. The building sector being responsible for carbon emissions, green building certification programs establish the current standards in order to construct green buildings, and such programs gradually are regularly updated to have standard levels increased. The Leadership in Energy and Environmental Design (LEED) program is widely used in over 150 countries in the world, including Canada. With standards higher than LEED, programs such as the Living Building Challenge (LBC) program, targets net-zero waste, water and energy. This paper outlines the current state of green buildings in Canada and the limiting factors of these buildings to reach standards of net-zero waste, water and energy, such as described by the Living Building Challenge program. Firstly, the paper describes Canada’s current green building standards by analyzing data of LEED certified buildings provided by the Canada Green Building Council. Second, a thorough analysis of the scorecards of the Platinum level buildings will be analyzed to identify the limiting factors of these buildings to achieve net-zero standards. Results indicate that the major limiting factor for each category is Water is Innovation and Technology, for Energy is to Optimize Energy Performance, and for Waste is Building Reuse.
