Use of Natural Energy

We are eager to use natural energy through efforts such as installing solar panels on terminal roofs and buying green electricity as part of our annual power consumption.
JAT aims to make Haneda Airport more eco-friendly.

Installation of Solar Power Systems

Terminal 1

<Terminal 1>

Terminal 2

<Terminal 2>

Recognizing the responsibility for the company engaged in the 24/7 operation of Haneda Airport passenger terminals, an important public infrastructure, JAT has installed solar power generation systems to contribute to CO2 emission reductions.
We will remain active in lightening the environmental impact of our terminal buildings.

Installation sites

(1) Four sites on the roof of Terminal 1 (1PTB)
(2) Two sites on the roof of Terminal 2 (2PTB)
(3) One site on the roof of the complete P4 parking structure (P4P)


(1) Systems in Terminals 1 and 2 ········ March 2010
(2) P4 parking structure ········ September 2010

Purchase of Green Electricity

Purchase of Green Electricity

Since FY 2008, JAT has purchased 3,000 MWh of green electricity annually, which accounts for a part of the annual power consumption of approximately 127,000 MWh (FY 2010 results) in domestic passenger terminal buildings at Haneda Airport.
Green electricity is eco-friendly electricity generated from natural energy sources, such as wind power and biomass, and is said to be produced without emitting carbon dioxide.
The purchased amount of green electricity is equal to the power consumed for the full-year operation of two see-through elevators each in Terminal 1 and Terminal 2, going up from the first basement level, as well as all the escalators.
