Installing megawatt-class photovoltaic power generation facility in Haneda Airport

Megawatt-class photovoltaic power generation panels are installed in our company’s facility in the domestic cargo terminal of Haneda Airport.
We are introducing clean energy by generating electricity equivalent to the consumption of 270 households annually to cover some of the electricity consumed by the company’s facility.
This plan is implemented as a green project that contributes to resolving environmental issues, including global warming, and some of the expenses for investment are financed through green bonds.

The photovoltaic power generation facility owned by our company annually generates electricity equivalent to about 3,100t emission of CO2 in total. We will continuously contribute to the reduction of CO2 emission through investment in renewable energy.

*1: CO2 reduction = 0.489 (CO2/kWh) (Conversion factor based on the periodic report according to the Tokyo Metropolitan Environmental Security Ordinance)
*2: CO2 reduction = 0.416(CO2/kWh)
(Conversion factor based on Singapore's Operating Margin Grid Emission Factor)

CO2 reduction

Donation of CO2 reduction to the Tokyo Metropolitan Government

Regarding environmental efforts, in addition to initiatives regarding renewable energy, our group is making active efforts to reduce CO2 emissions through facility investment for environmental measures, improvement of operation methods, educational activities to raise environmental awareness among employees in their daily work, etc. Such efforts resulted in emission reduction by our company and Tokyo Airport Heating & Cooling Co., Ltd., our group company, exceeding the required reduction level based on the Cap-and-Trade Program of the Tokyo Metropolitan Government (*1). In March 2020, we donated the excessive reduction (*2) to the Tokyo Metropolitan Government.

Total reduction of CO2 emission by the Airport Facilities Group

We received a letter of gratitude for the donation from the Tokyo Metropolitan Government in April 2020. We will continuously make active efforts to reduce CO2 emission to contribute in resolving the climate change issue.

*1 Cap-and-Trade Program of the Tokyo Metropolitan Government: An initiative to make it mandatory for large-scale facilities in Tokyo to reduce their CO2 emissions, and credit the reductions in emission achieved over the required level for trade among businesses
*2 As for excessive reduction during the first period, the total of the required reduction and the excessive reduction is larger than the actual reduction because the emission factor was reviewed due to the occurrence of the Great East Japan Earthquake (please refer to the Guidelines on the Operation of Emission Trading in Mandatory Reduction Targets and Emission Trade System).

Lightings inside the warehouse are changed to LED

For Rinku International Logistics Center, acquired in September 2001, electricity use is reduced by replacing the multi-halogen lamps used inside the warehouse with LED lighting. It also led to the improvement of work efficiency by improving worksite visibility with increased illuminance.

SD plant

About SD plant

Aircraft sewage treatment facilities (SD plant), treating sewage by utilizing microorganisms to comply with effluent standards, are concentrating the know-how of our company acquired through many years’ experience, and are currently working in eight different airports in Japan.
They contribute in the conservation of the water quality of rivers and oceans. In Haneda Airport, construction of a new plant was completed in March 2020 in anticipation of an increase in demand.
