| Exhaust gases from aircraft engines pollute the atmosphere. Materials used for washing, painting and maintaining the aircraft also pollute the air and water. JAL goes to great pains to reduce these pollutants. |

| At the maintenance facilities at Haneda and Narita airports, the water used for washing aircraft is collected and sent to a wastewater-treatment facility after use, then discharged or released for reuse after legally mandated water-quality controls have been carried out. In 1990, JAL established an automatic aircraft-washing facility at Narita — the only one of its kind in the world at that time. This helped increase operational efficiency and made it possible to achieve major reductions in the amount of detergent and water used for washing aircraft. |

| Damage to the surface paintwork on Boeing 747-400 aircraft necessitates repainting approximately every five and a half years. The old paint is removed before the new paint is applied, requiring the use of a large amount of paint remover. JAL collects all the paint-remover waste on plastic sheets and chemically processes it so that it can be safely discarded. |
