Emission Levels from Global Shipping
Shipping is the most fuel-efficient mode of transport, emitting 10-15 grams of CO₂ per ton-kilometer, compared to road freight (60-100 grams) and air freight (500 grams). However, despite its relative efficiency, shipping still accounts for about 3% of global CO₂ emissions. Reducing emissions in this sector is critical to achieving global climate goals.
Weather Routing for Fuel Savings and Emission Reductions
Weather routing uses weather data to optimize shipping routes, helping vessels avoid adverse weather conditions, reduce fuel consumption, and lower emissions.
- Fuel Savings: Research indicates that weather routing can reduce fuel consumption by 5-10% per voyage, and up to 15% on longer routes by optimizing routes to avoid headwinds, high waves, and adverse currents (source: ITF).
- CO₂ Reduction: By reducing fuel usage, weather routing can cut CO₂ emissions by 5-10%. According to DNV GL, this method also lowers other emissions like nitrogen oxides (NOx) and sulfur oxides (SOx).
- Global Impact: If adopted across the global fleet, weather routing could save 25 million tonnes of CO₂ annually, making a significant contribution to meeting global emissions reduction targets(source: WMU).
Economic Benefits
Beyond environmental impact, weather routing offers substantial economic savings. Shipping companies can save $50,000–$100,000 per voyage by optimizing fuel use, particularly on large vessels or long-haul routes. The improved operational efficiency also minimizes delays and reduces the need for detours, improving on-time delivery and reducing overall costs.
