Major Japanese airline All Nippon Airways says it is making all of its flights to and from Hiroshima Airport carbon neutral this month to coincide with the upcoming Group of Seven summit in the city of Hiroshima.

The carrier is undertaking the initiative with major natural resource developer Inpex and major oil wholesaler Idemitsu Kosan.

All 682 of the domestic flights connecting Hiroshima to Haneda in Tokyo, New Chitose in Hokkaido and Naha in Okinawa Prefecture will be supplied with jet fuel whose carbon dioxide emissions are offset through carbon credit trades.

The carrier says the initiative will help reduce emissions by nearly 10,000 tons.

Fuel procured through carbon credit trades is more expensive than conventional ones.

The three partners say they hope the initiative will raise momentum for achieving net zero emissions in the aviation industry.

Sustainable aviation fuel, or SAF, made from plants or discarded oil is expected to help cut greenhouse emissions from aircraft, but only a limited amount is available.

ANA official Muranushi Noriaki says SAF is scarce at the moment. He says the type of carbon neutral fuel his company is procuring is a promising way to achieve net zero emissions at airports across Japan.
