MacGregor, part of Cargotec, has won the GREEN4SEA Sustainability Award 2025, in recognition of the contribution its digital Carbon Calculator tool makes to maritime decarbonisation.

Available free of charge on the MacGregor website, Carbon Calculator allows container shipping companies to estimate the carbon dioxide emissions they can eliminate from their operations by upgrading their onboard container cargo system.

Maximising cargo-carrying capacity makes it possible to not only increase revenue potential but also cut fuel consumption per cargo tonnage carried, thereby minimising costs, CO2 emissions, and Emissions Trading Scheme (ETS) payments. With the MacGregor Carbon Calculator, owners can assess cargo system upgrade options based on operational data and scenario-based insights, supporting informed decisions that drive both sustainability and commercial success.

Accepting the Sustainability Award in a ceremony at the 14th GREEN4SEA Athens Forum on 12 March, Atte Virta, Naval Architect, Sales & Marketing, Customer Innovations, MacGregor, said: “There are countless actions that can be taken to improve cargo utilisation and reduce emissions per container carried. Establishing priorities will be based on an evaluation of impact and cost effectiveness.”

“MacGregor’s Carbon Calculator is a tool to tackle this challenge. The calculator provides quick, reliable estimates of the benefits of an upgrade. It shows the expected percentage reduction in CO2 emissions per twenty-foot container and savings in fuel costs and ETS payments in dollars per twenty-foot container, as well as potential added revenue.” says Magnus Sjöberg, Senior Vice President, Equipment and Solutions Division, MacGregor.

This gives shipping companies a clear view of the environmental and financial benefits of upgrading, helping them see the real impact on their path to decarbonisation. MacGregor Carbon Calculator is a commitment to a sustainable future for our planet.

Used to reveal opportunities for maritime decarbonisation that might otherwise remain hidden, Carbon Calculator is already trusted by some of the world’s top 10 container shipping companies as a first-step verification tool in their emissions-reduction journeys.
