Commercial Ships

Reducing emissions and driving efficiencies

The challenge

Decarbonising the Global Fleet

The IMO has established targets for the global shipping industry aiming to reach net-zero GHG emissions from international shipping by 2050. To meet this ambitious goal, effective pathways and initiatives must be identified and exploited across the sector.

BAR Technologies is leading in this arena, working to cut emissions and enhance operational efficency within the marine industry throught the development of patented products and unique technologies .

Our ability to draw on the latest and most advanced systems and technologies across design, construction and project management provide us with an impressive array of resources.


Wind Assisted Propulsion is a rapidly growing area of technological development within commercial shipping. The wind is a source of energy provided free-of-charge. Maximise your fleet fuel savings and emissions reductions via our state-of-the-art technology.

BAR Technologies’ WindWings® are the leading wind assisted propulsion technology on the market.

The general arrangement of conventional ship superstructures has not changed for 50 years, and they are aerodynamically inefficient. Now is the time for change.

AeroBridge® fulfils the function of the conventional block within an aerodynamically optimised geometry.

Hull Optimisation

Since its inception from the Americas Cup, BAR Technologies stands as a pioneer in advanced marine optimization.

Our distinctive toolkit, specifically developed for ship hull optimization, leverages AI-driven organic geometric creation, unique applications of CFD, and multi-objective optimization through machine learning. These tools greatly improve the time required for optimisation compared to the iterative processes previously employed. Designing with wind assisted propulsion technologies in mind – and the related increase in complexity – makes these techniques even more crucial.

Frequently asked questions

What proportion of global transportation emissions comes from commercial ships?

International shipping emissions had a year-on-year growth of nearly 5% percent in 2021, rising to approximately 700 million metric tons of carbon dioxide, accounting for approximately 11 percent of total global transportation CO₂ emissions that year. Emissions from international shipping have risen almost 90 percent since 1990, owing to increasing seaborne trade and the growing number of ships crossing the world's oceans.

Is zero-carbon shipping going to become a reality?

In the 2023 IMO GHG Strategy, there is a clear ambition to phase out GHG emissions from international shipping entirely, by the middle of this century. United Nations Secretary-General Antonio Guterres said, "We need to put the brake on deadly greenhouse gas emissions and drive climate action... The world is counting on all of us to rise to the challenge before it's too late." Research and development will be crucial, as the targets agreed in the 2023 IMO GHG Strategy will not be met using fossil fuels.

How will zero-carbon shipping be achieved?

Innovation, collaboration, policy and investment: Shipowners, shipyards, naval architects and innovative technology providers must work together to make zero-carbon ships more attractive and to direct investments towards innovative sustainable technologies. Policy makers must regulate against emissions and penalise accordlingy.
