Decarbonizing the maritime industry is crucial as a significant contributor to greenhouse gas emissions. With their pivotal role in maritime transportation and a vital trade hub, ports have a significant impact in terms of carbon emissions. Implementation of sustainable practices, such as shore power from renewable energy sources and providing green energy for port users, is a must to steer ports towards a cleaner future and can contribute to substantial progress towards tackling climate change, meeting sustainability goals, and protecting the well-being of local communities. Transforming ports into pioneers of a sustainable maritime industry will drive us closer to a low-carbon world and allow us to meet our obligation to protect the planet for future generations.
