Life Cycle Assessment

Life Cycle Assessment (LCA) is a comprehensive methodology employed to assess the environmental impact of products, services, or activities, covering the entire lifecycle from raw material extraction to waste disposal. In urban planning, LCA plays a pivotal role across various domains. For building projects, LCA aids in evaluating material choices, energy usage, and the environmental impacts during the construction phase, thereby promoting sustainable construction and infrastructure. In urban transportation planning, LCA is utilized to compare the environmental performance of different transportation modes, facilitating a shift towards more sustainable urban transportation practices. In summary, LCA provides a scientific foundation for urban planning, assisting decision-makers in making resource-efficient and environmentally friendly choices, ultimately contributing to the realization of sustainable development goals in cities.
