After nearly a decade of negotiations, the UN's International Maritime Organization has reached a groundbreaking agreement on combating polluting gases from ships. The deal requires large international vessels to transition to cleaner fuels or face fines, making the shipping industry the first with internationally mandated emission reduction targets. Various cleaner fuel options such as e-ammonia, e-hydrogen, and e-methanol are available for ships, with companies like Yara and Purus Maritime already investing in these alternatives. This move not only addresses the industry's 3% contribution to global heat-trapping gases but also aims to improve human health by reducing respiratory and cardiovascular risks. Economist Impact highlights the importance of reducing polluting gases in protecting marine biodiversity and restoring ecosystems. While hailed as a significant step, industry experts like Jesse Fahnestock emphasize the need for further actions. Individuals are encouraged to advocate for stricter shipping industry rules and consider investing in companies developing sustainable fuel sources and eco-friendly ships.
