The International Maritime Organization (IMO) is actively engaged in addressing the challenges of sea level rise and climate change through several important initiatives. IMO establishes international standards for the protection of the marine environment and promotes the sustainable management and conservation of marine ecosystems through various policies and programs. Notably, the organization implements key conventions such as MARPOL (International Convention for the Prevention of Pollution from Ships) and SOLAS (International Convention for the Safety of Life at Sea), which aim to reduce pollution and mitigate risks in marine environments. These regulations require ships to reduce greenhouse gas emissions, playing a critical role in combating climate change.

Moreover, IMO operates specific programs to address these challenges, notably the "Marine Climate Change Action Plan," which provides technical support and information to member states. This plan assists in assessing the risks associated with sea level rise and developing effective response strategies. Additionally, IMO promotes the establishment of Marine Protected Areas (MPAs) to preserve marine biodiversity and maintain ecosystem health. Finally, the organization strengthens technical and financial support for developing and vulnerable countries, enabling them to effectively tackle issues related to sea level rise. These efforts underscore IMO's commitment to collaborating with the international community to protect the marine environment.
