Analysis of floating city design solutions in the context of carbon neutrality-focus on Busan Oceanix City

Abstract

Excessive carbon emissions are causing global climate change, leading to higher temperatures and continued sea level rise, affecting all the world’s seaside cities. Concentrated population migration to large cities, flooding and rising sea levels are limiting the spatial growth potential of coastal urban water bodies. In response to climate change, the city of Busan, where sea levels are set to rise by 70.6 cm by 2100, is actively promoting the development of marine cities, and the development of marine space has become a hotspot. In response, the United Nations has proposed the world’s first floating city design scheme, Oceanix City. The aim of this thesis is to build a new type of carbon neutral floating city, by reviewing existing research papers on floating cities and carbon neutrality, analyzing in depth the carbon neutral design elements of the scheme, exploring the possibility of creating a zero carbon zone in the ocean and finally proposing alternative energy sources and design methods for marine cities. Using a case study approach, this thesis analyses carbon sequestration and carbon emissions, providing a theoretical basis for the design of future carbon-neutral floating cities with positive implications for achieving carbon neutrality. The study also proposes macro design criteria for a carbon neutral vision for floating cities, providing a theoretical basis and reference for the development of future floating cities.
