Stolt Tankers has said that a trial to burn biofuel on a transatlantic voyage has produced "very positive" results.

The Netherlands-based chemical carrier operator said a trip from Rotterdam to Houston showed a reduction in well-to-exhaust CO2 emissions of between 85% and 90% compared to conventional bunkers.

The 37,200-dwt Stolt Inspiration (built 1997) was partly powered by biofuel produced by Dutch group GoodFuels from sustainable and certified feedstocks.
