August 23, 2022 - TUI Cruises has always focused on climate protection. The cruise line is now having the targets for reducing its own emissions scientifically reviewed.

This is part of the TUI Group initiative, which submitted the reduction targets for its own cruise ships, hotels and aircraft to the non-governmental organization Science Based Targets Initiative (SBTi) for the entire tourism group. All targets now go through a rigorous verification process to ensure that the self-imposed, ambitious emission reduction targets are based on the latest climate science and are in line with the goals of the Paris Climate Agreement. The targets are expected to be verified by the end of this year.
The SBTi is a collaboration between the Carbon Disclosure Project (CDP), the UN Global Compact, the World Resources Institute (WRI) and the World Wide Fund for Nature (WWF). The initiative shows companies and financial institutions how much and how quickly they should reduce their emissions in order to achieve the goals agreed in the Paris climate agreement to combat global warming. More than 3.000 companies worldwide are already working with SBTi.
TUI Cruises has set itself the goal of operating the entire fleet (Mein Schiff & Hapag-Lloyd Cruises) in a climate-neutral manner by 2050 at the latest. By 2030, TUI Cruises wants to offer the first climate-neutral cruises and implement significant reductions in emissions. An important step in this direction is a concrete emissions roadmap, for which detailed investigations were carried out and action plans worked out. “Our cruise ships are already using the latest technologies to reduce emissions, so we already operate some of the most efficient cruise ships today. To achieve our ambitious goals, we will continue to invest in sustainability, test applicable cruise solutions and enter into innovative partnerships,” says Wybcke Meier, CEO of TUI Cruises.
The main strategy for decarbonization in the short term is the expansion of green shore power use, the addition of second-generation bio-fuels (fuels, from residues/waste from production and industrial processes) and the technical development of drive technologies for the use of so-called e-fuels (fuels, synthetically produced with the help of renewable energies) in the future. This is flanked by numerous measures such as energy efficiency measures, heavy oil-free new buildings, expansion of marine diesel use and use of synthetic fuels when they are ready for the market and available.
Equipment of the ships & measures to reduce emissions at a glance
- My ship / today: All Mein Schiff newbuilds are characterized by excellent energy efficiency. In addition, they are equipped with a combined exhaust aftertreatment system consisting of a scrubber and catalytic converters, which is in use around the clock worldwide and reduces sulfur emissions by up to 99 percent, nitrogen oxide emissions by up to 75 percent and particle emissions by up to 60 percent reduced. The exhaust gas values achieved in this way are comparable to those of marine diesel.
- My ship / planned newbuildings: The three other cruise ships that will complement the Mein Schiff fleet by 2026 will not use heavy fuel oil: In 2024, Mein Schiff 7 will be put into service, which will be operated with lower-emission marine diesel (sulphur content: 0,1%) and with catalytic converters (nitrogen oxide reduction: approx. 75%) and a shore power connection. In addition, Mein Schiff 7 will be built in such a way that the ship can also run on methanol or green methanol. In 2024 and 2026, two ships will follow that run on liquefied natural gas (LNG). The investment in liquid gas-powered ships is an important milestone on the way to emission-free and climate-neutral cruises. LNG serves as a bridging technology here. So-called bio-LNG, which is generated either from biogenic sources or synthetically from renewable energy, will be used in the future.
- Hapag Lloyd Cruises: The entire Hapag-Lloyd Cruises fleet has been using marine gas oil with a maximum sulfur content of 2020 percent (MGO) since 0,1. All new buildings since 2013 also have SCR catalytic converters, which reduce nitrogen oxide emissions by around 75 percent.
- Shore power usage: Some ships of both fleets already use shore power, if available in the ports. In the future, all cruise ships of both fleets will use shore power for almost emission-free operation in the port - with the exception of one ship that can no longer be technically upgraded. TUI Cruises is pursuing the goal of further expanding the shore power supply in the ports. At the same time, TUI Cruises also sees the ports as having an obligation: on the one hand, the range of shore power systems must be expanded. On the other hand, the ports must present a green electricity concept. This is the only way to ensure that emissions are not shifted to other areas.
- Energy efficiency: The most effective way to reduce emissions is to use less fuel. On the one hand, this is due to the shape of the hull, which makes it particularly easy for the newbuilds to glide through the water. In addition, the timetables are designed according to the "slow steaming" principle, so that the ships travel in a fuel-efficient manner. This includes both low speeds and the shortest possible distances between ports. TUI Cruises also relies on energy-saving solutions in daily ship operations.
