Cargill this week said it would continue to push for CO2 reductions across its fleet and wider operations.

In 2017, Cargill's ocean transportation business reduced its CO2 emissions by 5.7% and committed to achieving a 15% reduction by 2020.

The firm also wants to cut gross greenhouse gas emissions by 10% by 2020 across its global operations.

"We are relatively pleased with our fleet performance this year. We know vessel efficiency can vary considerably due to a host of external factors but the whole team at Cargill is committed to achieving a significant improvement in coming years," said Jan Dieleman, president of Cargill's ocean transportation business.

"Sustainable shipping can only become a reality if the entire industry pulls in the same direction. The hard work certainly lies ahead of us and we will embrace it."
