Japan Airlines will introduce procedures on its flights to San Francisco aimed at reducing carbon dioxide emissions by 658t per year.

The airline will implement user preferred routes (UPR) procedures, which sees the use of customised lateral flight profiles on the route. The airline will also implement continuous descent operations (CDO) - which allows for more gradual descent further out from the destination airport - and reduced oceanic separation minima (OSM) of 30nm (55.5km) when flying into San Francisco.

JAL also has authorisation to use UPRs to Hawaii and Australia, CDO at San Francisco and Kansai International airports and OSM on North American routes.

The procedures were introduced by the Asia and Pacific Initiative to Reduce Emissions (ASPIRE), and JAL has become the first Japanese airline to be qualified by ASPIRE to use the procedures.

JAL adds that the measures are expected to yield an annual saving in fuel burn of 250,000 litres, resulting in the associated reduction in emissions.

ASPIRE was formed in 2008 as a collaborative project between several air navigation service providers in Asia and the US and airlines aimed at implementing procedures that would cut fuel consumption on oceanic flights across the Pacific.
