Referenced laws, regulations, guidelines and emission coefficient

“Act on Rational Use of Energy and Conversion into Non-Fossil Fuel, Etc.”
“Act on Promotion of Global Warming Countermeasures”
“Table of heat generation and carbon emission coefficient by energy source” (METI)
IEA Emission Factors(International Energy Agency)
Carbon emission coefficient based on the calculation method developed by Japan Federation of Construction Contractors

Calculation method

CO₂ emissions are calculated by multiplying energy consumption (including crude oil, light oil, gas and electricity) by CO₂ emission coefficient
With regard to a portion of electricity/gas consumption (3% of the total for electricity, 6% for gas) for which bill payment is not outsourced to payment service providers, the amount is estimated based on electricity/gas consumption per unit of sales.
Calculation method for CO₂ emissions from completed construction works by POC on an unconsolidated basis
CO₂ emissions from completed construction works by POC on an unconsolidated basis = CO₂ emissions from all construction works (excluding projects undertaken as a JV sub member)/ Net sales of all completed construction contracts(excluding projects undertaken as a JV sub member) x Net sales of completed construction contracts of POC on an unconsolidated basis
Calculation method of CO₂ emissions of POC group
CO₂ emissions of POC group = CO₂ emissions of POC on an unconsolidated basis/Net sales of POC on an unconsolidated basis x Net sales of POC Group

Comprehensive Assessment System for Built Environment Efficiency (CASBEE) Evaluation Manual (Japan Sustainable Building Consortium)

Calculation method

Category 1 (purchased goods and services): Calculated by multiplying the purchase quantities or price of the major construction materials (steel, concrete and cement) by emission coefficient CO₂ emissions of POC Group were estimated by scaling CO₂ emissions of POC on an unconsolidated basis in proportion to sales volume
Category 11 (use of sold products): Calculated by multiplying the total floor area of completed construction projects by POC Group in the relevant year by emission coefficient determined for each building use and the years of service life (CASBEE Evaluation Manual).
Other categories include Categories 2, 3, 4, 5, 6, 7 and 12.

Referenced Laws and regulations

Calculation method

Calculated based on manifests for all construction projects (excluding projects undertaken as a JV sub member) by POC

Referenced laws and regulations

Calculation method

Calculated based on bills from power companies.
With regard to a portion of electricity consumption (3% of the total) for which bill payment is not outsourced to payment service providers, the amount is estimated based on electricity consumption per unit of sales.
Calculation method of electricity consumption from completed construction works by POC on an unconsolidated basis
Electricity consumption from completed construction works by POC on an unconsolidated basis = Electricity consumption from all construction works (excluding project undertaken as a JV sub member) /Net sales of all completed construction contracts (excluding projects undertaken as a JV sub member) /Net sales of completed construction contracts of POC on an unconsolidated basis
