Category Life cycle stage List
Scope 1 Direct emission Construction · Fossil fuel usage of used equipment when material transportation
· Fossil fuels(diesel, gasoline) usage of used equipment for construction work like earth work, excavation
Operation and maintenance · Fossil fuel usage for maintenance of facilities(maintenance, repair and etc.)
Demolition and recycling · Fossil fuel usage of equipment for waste transport
· Fossil fuel usage of used construction equipment for blasting and cracking
Scope 2 Indirect emission Construction · Used utilities(electricity, gas and etc.) for heating and cooling in field office
· Operated equipment which use electricity
Operation and maintenance · Used utilities(electricity, steam and etc.) for heating and cooling of road infrastructure(rest area, management office and etc.)
· Used utilities(electricity) in road infrastructure(tunnel lamp at night, vent and etc.)
Demolition and recycling · Used utilities(electricity, gas and etc.) for heating and cooling in field office
· Operated equipment which use electricity
