Previous reporting utilized the energy content method. Prior year values have been updated in this report to reflect the work potential method. 4 A correction was made to an emission factor used for electricity purchases. 5 A correction was made to the quantity of steam purchased and consumed. 6 Emissions from Category 9: Downstream Transportation & Distribution have been realigned to Category 4: Upstream Transportation & Distribution to comply with the GHG Protocol.
