Connecticut-based Penfield Marine says it has become the first tanker pool to execute a carbon-neutral voyage.

Penfield, a leading commercial manager and pools operator, said it carried out the voyage in conjunction with the Macquarie Group’s commodities and global markets division using the 158,400-dwt Seaways Hatteras (built 2017), a suezmax owned by New York-listed International Seaways.

Penfield is now collaborating with Macquarie to offer what it calls “environmentally differentiated freight products” to its customers.
