The type and quality of emissions, activity and infrastructure data available for use in this emissions inventory has improved and enables a progressively more refined assessment compared to previous inventories for the UOG sector (ECCC, 2014). The updated inventory is intended for use by the Alberta Energy Regulator (AER) and its evaluation of methane emissions from the UOG sector. As such, inventory refinements and boundaries considered in this report focus on subsectors and activities contributing the most to UOG methane emissions. This effort may also inform Canada’s National Inventory Report submission to the UNFCCC Secretariat. Moreover, software tools developed by this project may be leveraged to establish a methane baseline (for 2012 and/or 2014 inventory years) and demonstrate achievement of provincially and federally stated methane reduction targets.
