Lowering speeds at sea is one of several factors that reduce the pollution resulting from the shipping industry.
International shipping faces major environment-related challenges.
Currently, the average age of cargo ships world-wide is 18 years. Rebuilding old engines can also be helpful. Operational adjustments such as lower cruising speeds at sea can have a significant effect. High speeds result in considerably higher emissions than low speeds. Emission quotas represent a possible approach, but it will take considerable time to gain acceptance for this solution.
