Green Worldwide Shipping has launched a new program, Greenbox Consolidations Program, that connects Hamburg, port of loading Bremerhaven, and Savannah through a weekly ocean service powered by Green’s Sustainable Maritime Fuel certificates (SMFc). The company said it has built-in certified fuel cuts, slashing maritime emissions by 90%.
Each 40-foot-high cube container used in the program accounts for 9,138 TEU nautical miles of shipping activity, which Green matches with low-emission fuel certificates procured through their participation in the Zero Emission Maritime Buyers Alliance (ZEMBA). ZEMBA is a global coalition of cargo owners driving commercial adoption of zero-emission shipping through demand aggregation. The alliance uses a book and claim model to enable zero-emission shipping claims across all trade lanes, including those linking the European Union and the United States.
As sustainability reporting requirements expand across major trade markets, importers are being held to higher standards of transparency and action on Scope 3 emissions. Achieving decarbonization targets depends on reliable data, transparent reporting, and logistics models built with sustainability in mind. Through its new GreenBox Consolidations program, Green Worldwide Shipping (Green) incorporates sustainability into the shipment process, taking environmental responsibility from policy to practice.
“Our relationships across Europe continue to influence how we innovate globally,” said Thomas Jorgensen, CEO | Green Worldwide Shipping. “GreenBox Consolidations represent more than a new service. They reflect our ongoing commitment to measurable decarbonization and transparency, even in a volatile market. By embedding certified maritime fuel insets into every Hamburg-Savannah consolidation shipment, we are reducing emissions in our value chain and advancing our long-term goal to become one of the most sustainable freight forwarders in the world.”
Each GreenBox shipment is documented with verifiable data linking cargo movement to certified emission reductions. Shippers receive a formal statement monthly confirming their impact, and Green retires each participant’s share of SMFc in the Katalist registry for ESG and Scope 3 reporting. This approach provides companies with auditable data that supports regulatory reporting and demonstrates measurable progress toward sustainability objectives.
The company said these certified maritime fuel insets reduce greenhouse gas emissions by more than 90% on a lifecycle basis compared to conventional bunker fuel and directly support the scale-up of zero-emission maritime energy.
