p. 57 & 86- a.) Original numbers reported as percentages of the total GHG emissions. Scope 1 accounts for 45% of 242,924 metric tons of CO2e. b.) The emissions calculations include greenhouse gases covered by the Kyoto Protocol: carbon dioxide (CO2), methane(CH4), nitrous oxide (N2O),

hydrofluorocarbons (HFCs),perfluorocarbons

(PFCs) and sulphur hexafluoride (SF6) and

are reported as CO2 equivalent. d.) base year not included. e.) Greenhouse gas emissions are calculated following the Greenhouse Gas (GHG) Protocol. The report includes Scope 1 and Scope 2 emissions, while information on

Scope 3 emissions can be found in our GRI Content Index. The organizational boundaries for this report align with the Operational Control approach outlined in the GHG Protocol. For direct emissions, appropriate emission factors from the IPCC 2006 Guidelines for National Greenhouse Gas Inventories and the EPA's Fugitive Emissions Guidance are used. For electricity, the latest regional emission factors are supplied by the Environmental Protection Agency (EPA) and the International Energy Agency (IEA), while emission factors for steam and process derived fuels are specific for each site and are provided by the suppliers. f.) The global

warming potential of each gas is provided

in the IPCC Second Assessment Report. g.) not specified in report
