Act on Promotion of Global Warming Countermeasures (Global Warming Countermeasures Act)
Greenhouse Gas Protocol Initiatives (GHG Protocol)
Emissions per base unit of construction (t-CO2/net sales on completed construction (per ¥100 million) calculated at specified construction sites

Based on the calculation method specified by the Japan Federation of Construction Contractors

Energy used at construction sites is measured and calculated for each type of energy as shown below.
  • Electric power: Calculated using the 2018 emissions factor of 0.461 t-CO2/MWh for end use announced by the Japan Business Federation . CO2 Emissions from Fuel Combustion 2019 (International Energy Agency) is used to calculated emissions from electric power overseas.
  • Kerosine and heavy oil A: Measured from the volume purchased. Calculated using the emissions factors in the Energy Conservation Act and the Global Warming Countermeasures Act.
  • Volume of diesel used by trucks and heavy machinery: Calculated according to the formula, volume of waste and construction-generated soil transported x base unit for volume of diesel used + number of days trucks and heavy machinery are operated onsite x base unit for volume of diesel used (based on the calculation method of the Japan Federation of Construction Contractors).

The survey period for energy used during and CO2 emissions from construction is the calendar year.
