The decarbonization of maritime transport is crucial in achieving global climate goals. With the sector responsible for around 1 GtCO2eq annually, efforts to reduce emissions are imperative. The International Maritime Organization (IMO) has set targets to reduce greenhouse gas emissions from shipping by at least 40% by 2030 and 50% by 2050 compared to 2008 levels. Strategies for decarbonizing ports include electrification of equipment and infrastructure, adoption of alternative fuels like hydrogen and ammonia, and integration of renewable energy sources such as wind and solar. The shift towards Environmental, Social, and Governance (ESG) assessments in shipping companies promotes sustainability and corporate social responsibility. Technologies like lithium-ion batteries and cold ironing are being employed to reduce emissions during port operations. Overall, decarbonizing the maritime sector presents opportunities for a greener and more sustainable future.
