The central objective of establishing the 2030 Agenda for Sustainable Development targets to develop well-being for every individual together with mandatory environmental protection and improved future wellness. The achievement of SDGs depends heavily on Blue-Green Infrastructure (BGI) because it creates sustainable resource-efficient living environments. The BGI network uses urban planning combined with ecological restoration and infrastructure development to build links between people and nature which delivers essential solutions to urban along with climate issues. BGI uses “blue” to symbolize water bodies of rivers and tanks alongside “green” symbols for trees gardens and parks. The BGI concept benefits diverse economic environmental and social dimensions simultaneously. The system helps regional ecosystem management and decreases pollutants while cooling urban temperatures. Building terrace gardens demonstrate a climate-benefiting function because they lower building surface temperatures which leads to decreased energy requirements. The combination of minimized raw materials usage with pollution control and emission reductions at BGI results in economic advantages for the area. Urban development in developing nations proves a main obstacle for sustainable development so new approaches to city planning and environmental control become essential. Blue-Green Infrastructure functions as an agent through which the Sustainable Development Goals can be achieved because it combines natural areas with built structures to build resilience and improve efficiency of resources and ecosystem function. Energy infrastructure development will require policies that unite for BGI implementations together with financial modernization systems and engaged local community support to embed this solution into urban blueprint design. The effectiveness of BGI depends on the development of better governance systems and the use of technological tools for assessment together with support from different stakeholders. The chapter investigates BGI's contributions to SDG implementation at the local level while discussing its underlying features together with their pros and their limitations. Well-designed BGI demonstrates its capacity to produce many beneficial effects for society by achieving direct SDG targets as well as remotely connected targets thus delivering substantial contributions toward achieving the SDGs.
