Why cruise ships are catastrophic for the planet?



Marine transportation still generates negative impacts on the marine environment, including air pollution, greenhouse gas emissions, releases of ballast water. Shipping emits 1,000 Mt CO2 per year, which is 3% of global CO2 emissions. According to the International Maritime Organisation, The cruise industry is a major sector within global tourism and maritime travel, offering experiences on ships that operate in various regions worldwide. The global cruise industry is booming, with passenger numbers expected to reach 33.7 million this year. But this rapid growth comes with serious environmental impacts. It is estimated that about 50 tons of solid waste are generated on a one-week cruise.



2025 worldwide ocean cruise line revenue from ticket and onboard spend is estimated at $72.5 billion (a 7.7% increase over 2024) with 33.7 million annualized passengers carried (a 4.9% increase over 2024).

Spectrum coordination at sea.

ITU facilitates lifesaving and eco-conscious maritime operations through radio spectrum management and global technology standards. Maritime operations worldwide rely on ITU’s Maritime Manual , List IV (coast stations) and List V (ship stations), alongside the Maritime Mobile Access and Retrieval System (MARS) , which makes available information on over 900,000 vessels and more than 2,000 coast stations. These tools are indispensable for timely search and rescue responses, as well as for pollution incident reporting under MARPOL, the cornerstone convention maintained by IMO to prevent marine environment pollution from ships . Just as importantly, the Global Maritime Distress and Safety System (GMDSS) developed by ITU and IMO enables ships in distress to promptly alert rescuers, saving human lives and reducing environmental harm. Improved situational awareness reduces risks of collisions, groundings and oil spills, which can be disastrous for the marine environment.

Enhance Maritime traffic management.

Today, ships rely upon real-time navigational data , such as traffic reports, weather forecasts and sea condition updates. Access to live digital information enhances vessel routing and planning, directly improving fuel efficiency , reducing greenhouse gas emissions , and decreasing the risk of waste discharge from ships. Modern radiocommunication technologies and navigation aids , combined with coast stations and other shore-based facilities, let maritime operators track ships and control vessel traffic smoothly. This is especially important in busy channels and ports or in any environmentally sensitive area. With maritime traffic growing globally, the integration of advanced communication technologies becomes ever more important. Data for ocean monitoring comes from satellites and terrestrial communication systems spanning the globe. Earth-observation satellites and myriad radio technologies also help monitor fishing vessels, ensuring responsible practices that safeguard fish s...

Improve safety at sea and safeguard marine environments.

Image
The world’s oceans are a vital source of food, energy and biodiversity. They play a central role in regulating the planet’s climate. However, they are under increasing pressure from pollution, overexploitation, habitat degradation and climate change. Every day, those vast expanses are traversed by a wide variety of vessels, from cargo ships and fishing boats to pleasure craft and passenger ferries. Modern communication technologies are essential for the safe, secure and efficient operation of all vessels at sea , which is fundamental to protecting the fragile marine environment. The  International Telecommunication Union (ITU)  has been continually improving maritime radiocommunication systems since the early 1900s. Today, as the United Nations agency for digital technologies, ITU still meets the ever-evolving needs of the maritime community. Whenever governments, the shipping industry, engineers or mariners identify a new technical or operational requirement, ITU is there to...
