A tanker controlled by John Fredriksen's Frontline has bunkered with biofuel blend in a bid to tackle CO2 emissions.

On Tuesday, the New York and Oslo-listed shipowner's 110,000-dwt Front Leopard (built 2016) departed Rotterdam using the new fuel.

Fredriksen, chairman of Frontline and owner of Seatankers Management, claimed the fuel will lead to a significant cut in CO2 emissions.
