Maritime shipping companies worldwide are committing to reduce their carbon emissions.
Maersk Line, one of the world’s largest container shipping company, “has set a voluntary target to reduce CO2 emissions from its container vessels by 20 percent per container moved in the period 2007-2017.”
It makes environmental and financial sense, since one of the best ways to reduce carbon emissions from ships is to curb fuel consumption, which of course saves money.
According to Stephen Cahill of WFP Shipping, voyage optimization, or weather routing – using the latest weather and ocean current information to better plot voyages – is one of the top 10 green trends in shipping, and a key strategy the shipping industry is using to reduce fuel use, costs and carbon emissions.
We invite you to give us your feedback as our experts weigh in on the top five ways to save fuel, CO2 and costs by using ship routing.

Top Five Ways Ship Routing Reduces Fuel, C02 Emissions, Costs
by AWT Staff
AWT has demonstrated how our ship routing services can reduce fuel consumption by five to 10 percent. So this month, we asked AWT staff members to give you their tips for using ship routing to reduce fuel consumption and carbon emissions:
1) Travel at More Efficient Speeds
No doubt you’ve heard about slow steaming, the strategy that companies are using to reduce emissions by curbing top speeds.
Along similar lines, with ship routing services such as AWT’s Fuel Optimization Service, Captains and fleet managers can get the information they need to travel at slower, more constant speeds – and even a small downward adjustment in speed can amount to substantial fuel savings and corresponding greenhouse gas emissions.
Travel at More Efficient SpeedsThe service takes into account numerous operational and environmental factors to give Captains and fleet managers speed-setting guidance along an optimum route in order to safely and efficiently achieve a desired ETA. Incorporating expected weather and ocean current data continuously along the route with built-in safety margins, the service provides the information needed to help Captains and fleet managers confidently operate vessels at their most efficient speeds during their entire voyages, helping to ensure that loading and discharging schedules are still met with the least amount of fuel consumed.
2) Leverage Long-Range Forecasts and Climatological Data to Get a Strategic Route
Many Captains use short-range forecasts for making their routing decisions, which can be beneficial in situations such as avoiding an individual low-pressure system, but using short-range forecasts without considering long-range ones and historical climate data could easily put vessels in locations where they might be exposed to prolonged adverse conditions on the remainder of their voyages.
Ships in such situations are often delayed for days at sea, causing excessive, unexpected and unnecessary fuel consumption and carbon emissions. These problems can often be avoided with strategic weather routing. Strategic weather routing uses short- and long-range forecasts along with climatological data to evaluate the best route to minimize time en-route, fuel consumption and exposure to prolonged adverse conditions that could lead to safety issues, damage and delays.
Leverage Long-Range Forecasts and Climatological DataThe combination of AWT’s 16-Day Forecasts and Climatological Ship Resistance Model provides the tools to strategically determine the optimum time or fuel route. Although the exact location of a specific gale or storm may not be verified beyond 10 days, the real key is determining the storm track. By understanding the intensity and where the system is developing and moving, a Captain or Route Analyst can strategically determine the best route. Then once a vessel is within three to five days of a specific gale or storm, the route can be tactically adjusted to safely and efficiently clear that individual system.
