Nova Marine Carriers, a Swiss-Italian dry bulk shipping operator, said on Thursday it has undertaken its first carbon-neutral voyage in Italian waters.

It offset 94 tonnes of CO2 emitted from a trip of the 8,100-dwt Sider Rodi (built 2010) by purchasing carbon credits for a solar farm in Madagascar.

More such deals are likely to emerge as maritime companies seek to improve their green credentials and comply with tighter environmental rules — especially in Europe, which is set to apply its emissions trading system to shipping from 2023.
