Abstract

Climate change casts a long shadow over densely populated cities, which is a consequence of the greenhouse gas emissions. Consequently, a critical concern regarding the environmental condition was caused. Zero-emission neighborhoods offer a promising solution but designing them effectively requires balancing complex factors. The neighbourhood is divided into components such as: buildings, mobility, infrastructure, and on-site energy, which were analysed separately to facilitate deeper comprehension of the neighbourhood emission pattern, according to its ambition levels. The aim of this study was to utilize a GIS model that integrates LCA at initial stages of neighbourhood’s design, in order to identify the key factors that contribute to carbon emissions. The results of the case study of New Obour City highlighted buildings, particularly during their operational phase, as major emitters, followed by the production phase. On the other hand, neighbourhood infrastructure emitted the least emissions during its life cycle. Consequently, building design should be prioritized in order to reduce energy consumption, and pave the way for a future where cities and communities thrive in harmony with the environment.
