The maritime industry is responsible for transporting 90% of global goods, but it also emits over 1 billion tonnes of carbon annually and faces increasing regulatory pressures to reduce emissions. Technology opportunities, such as exhaust gas cleaning systems and ballast water treatment systems, are emerging to help meet these regulations, but uptake is hindered by costs, the need for compliance, and financial access. Overall, innovation and investment in new technologies are crucial for the industry's transition to a more sustainable future.
