Rather than pinning its decarbonization hopes on future tonnage, shipping can pursue its goals today by retrofitting available technology to existing, conventionally fueled vessels, explains David Sakandelidze, Business Manager for Energy and Efficiency, Berg Propulsion.The International Maritime Organization's (IMO) target for net-zero emissions from ships by around 2050 is now only 24 years away—less than the average lifetime of a commercial ship. Today, 112,000 active vessels emit approximately 1.05 billion metric tons of combined annual emissions.
