Energy and our Carbon Footprint
To calculate our carbon footprint and greenhouse gas (GHG) inventory, we referenced the Greenhouse Gas Protocol Corporate Accounting Standard published by the World Business Council for Sustainable Development and the World Resources Institute. Our analysis covers directly leased or owned facilities on which we have operational control, and includes both direct (Scope 1) and indirect (Scope 2) emissions. Scope 1 emissions refer to emissions generated as a result of building and space heaters, and Scope 2 emissions refer to emissions generated as a result of purchased electricity from utilities and other energy providers.
Our total carbon footprint in 2014 for North America was 34,461 metric tons CO2e. Electricity consumption had the largest overall impact on our carbon footprint and accounted for 97% of total emissions.
