The 2024 Climate Design Summit, held on October 29, 2024, emphasized the importance of interdisciplinary approaches in tackling climate change challenges. Experts from architecture, engineering, and environmental science gathered to discuss sustainable solutions for mitigating climate disasters like floods, wildfires, and droughts. The summit advocated for cross-disciplinary solutions that integrate Nature-based Solutions as catalysts for climate resilience and are essential for long-term sustainability, and stressed that no single technical solution can address the complexity of climate issues. Successful case studies were highlighted as examples of how design can address both climate resilience and socio-economic challenges. The gathered insights and discussions on this summit reinforced that achieving climate resilience requires a holistic approach that blends scientific innovation, sustainable design, and community empowerment, and underlined the need for collaboration across disciplines and sectors to build resilient cities and infrastructures.
Urban green-blue infrastructures (GBIs) are increasingly gaining attention in the pursuit of carbon neutrality, particularly within residential areas. With this background, this study established an integrated quantitative framework to assess both direct and indirect carbon reduction benefits of urban GBIs, by leveraging Life Cycle Assessment approach to precisely calibrate the carbon sequestration benefits of three typical urban GBIs (green roofs, sunken green spaces, and rain gardens) under three different scenarios and building a carbon sequestration database that includes 36 local plant species in Shanghai. The research results indicate that GBIs have a reducing effect on carbon emissions in urban residential areas. If extrapolating the simulation results to the city scale, the preliminary estimation suggests that the construction of GBIs within residential areas in Shanghai can achieve a carbon sink of approximately 540.54 million tCO2eq per year. This level of carbon sequestration is equivalent to 32% of Shanghai’s annual carbon emissions. It is evident that the construction of GBIs possesses significant potential in carbon reduction benefits and for achieving urban carbon neutrality strategies.
