<p><strong><em> </em></strong>International maritime trade has long played a pivotal role in human development; however, its environmental impact cannot be disregarded. Air pollution (that includes Carbon and Sulphur emissions—all together Greenhouse Gases) emanating from ships has emerged as a significant contributor to climate change, prompting growing concern among the international community. The combustion of fossil fuels in ship engines releases pollutants such as sulfur dioxide, nitrogen oxides, and particulate matter into the atmosphere, adversely affecting both human health and the climate. In recognition of the need to tackle this issue, international laws have been established to regulate ship emissions. This research paper analysed the IMO’s regulations under international law for mitigating climate change, with a particular focus on various global initiatives controlling sulphur, carbon and GHG emissions. It is suggested that cooperation between public and private interests as well as at regional levels will play a crucial role in combating climate change and promoting global shipping sustainability.</p>
