Dutch carrier KLM has launched its latest biofuel initiative, operating “a series” of weekly flights between New York JFK and Amsterdam Schiphol using a mix of biofuel and traditional kerosene.

The biofuel service will operate every Thursday on flight KL642, using a B777-200 aircraft emblazoned with the words “We fly on biofuel”.

It’s not clear how long the initiative will last, but in a statement KLM said that its shows that “sustainable biofuel in the airline industry is here to stay”.

The biofuel flights are a result of “a joint effort and expanded cooperation between KLM, Schiphol Group, Delta Air Lines, the Port Authority of New York and New Jersey and by contributions of KLM’s partners in the Corporate BioFuel Programme”.

Last year KLM operated the world’s longest flight using biofuel, when it flew between Amsterdam and Rio de Janeiro to mark the Rio +20 conference on sustainable development (see online news June 19, 2012).
