p. 21- Original data given as 1.39 million tons of CO2e and converted to metric tons of CO2e. b.) specific gases not disclosed in report, c.) base year is 2010, rationale not given. d.) Scope 1: In the United States we follow the requirements for the GHG MRR (Mandatory Reporting Rule) to calculate emissions. Methodologies include use of default factors (2007 International Panel on Climate Change (IPCC) guidelines), fuel tests and CO2 Continuous Emission Monitoring Systems (CEMS) devices on certain units. Outside the U.S. sites follow the 2007 IPCC guidelines. Scope 2: Sites follow the 2007 IPCC guidelines and U.S. facilities use state specific emission factors provided by The Emissions & Generation Resource Integrated Database (eGRID). e.) not included in report
