Maritime archaeology has been identified as a significant field among the humanities that could contribute to the global sustainable development agenda. This article explores the relevance of maritime archaeological studies to initiatives of climate action. Βy reviewing the contributions of various state-of-the-art projects and by linking their aims and outcomes to specific targets of the UN Sustainable Development Goals, the author highlights the benefits of involving maritime archaeological research in the pursuit of sustainability and climate resilience. This involvement could play a key role in reinforcing human-centred and culturally aware solutions to the current climate change effects that threaten human populations, especially in maritime regions. It is hoped that this discussion will inspire researchers in the humanities, archaeology, and maritime archaeology in particular, to use their expertise within the framework provided by the sustainable development agenda to help build a better future.
