In corporate greenhouse gas emission accounting and reporting, it is important to define a clear operational boundary for the organization concerned. Three ‘‘scopes’’ are defined for this purpose in the GHG Protocol Corporate Standard (WBCSD, 2004). Scope 1 accounts for direct GHG emissions from sources that are owned or controlled by the company. Scope 2 is electricity indirect GHG emissions. As the name indicates, it is about GHG emissions from the generation of purchased electricity consumed by the company. Scopes 3 includes other indirect GHG emissions, such as emissions from the transportation of purchased fuels. In this study, only scopes 1 and 2 are accounted. This is in line with the Standard’s requirements, which set scope 3 as an optional reporting category. For this specific case, emissions from combustion of gas and diesel in cooking facilities and boilers fall into scope 1, while emissions from using purchased electricity should be accounted in scope 2.
