In the first half of 2025, AIDA Cruises burned over 3,300 tonnes of ISCC EU-certified bio-LNG aboard AIDAnova, with deliveries in Hamburg, Kiel, and Zeebrugge. By the end of August 2025, the line had achieved more than 250 shore-power connections across its fleet, a number expected to surpass 400 by year’s end.
These measures are part of a broader decarbonization and modernization strategy under AIDA’s “Evolution” program, which includes the construction of new vessels due for delivery in spring 2030 and winter 2031–32. The future newbuilds will be equipped for multi-fuel propulsion and will be ready to use both bio-fuels and e-fuels once those energy sources become more widely available.
AIDA has also conducted pilot projects to test very low-emission biofuels: in 2024, AIDAprima operated on 100% residual biofuel (BMF 100), which its manufacturer reports delivers over 90 % CO₂ emissions reduction under the test conditions.
Meanwhile, shore power has become a central element of AIDA’s port operations. In 2024, the fleet logged 381 connections in European ports, up from 65 in 2023. Ports across Germany (Hamburg, Kiel, Warnemünde), as well as in Oslo, Stockholm, and Copenhagen, are among those now equipped. Once docked, AIDA ships are able to shut down main engines and use port electricity for onboard systems, which can reduce emissions by up to 98%, depending on the local energy mix and infrastructure.
Other efficiency measures are in active deployment. AIDAprima carries a 10 MWh battery storage system used for peak shaving—i.e., stabilizing engine loads by drawing on stored energy when demand spikes—to reduce fuel consumption. Across the fleet, investments continue into improvements such as air conditioning, refrigeration, waste heat recovery, LED lighting, and use of data analytics and AI to optimize energy use.
Overall, AIDA’s technical improvements, fuel sourcing, shore power usage, and future fuel readiness are being presented as practical steps toward meeting climate goals set by the EU, IMO, and in alignment with its own net-zero ambitions.
