C-Zero Maritime

Low-carbon solutions for the global shipping sector.

Decarbonising Maritime Supply Chains

C-Zero Maritime is a dedicated division of C-Zero Markets, created in partnership with WPS to help ship owners and operators cut their environmental impact, meet regulatory requirements, and strengthen their competitive edge.

By combining C-Zero’s market-leading expertise in environmental commodities with WPS’s proven Platform 13 technology, C-Zero Maritime delivers credible measurement, reporting, and offsetting of Scope 3 emissions across the entire shipping lifecycle — from individual port calls to full sea voyages.

The Pressure to Act

Over 6,500 companies are registered with the Science Based Targets Initiative (SBTI), all working towards net-zero. Many rely on shipping for global trade — and they expect their supply chain to decarbonise.
From tenders to long-term contracts, environmental credentials are now a competitive advantage in shipping.
