Abstract
This article examines the role of engineering in promoting sustainable urban-infrastructure development, focusing on sustainable development goal 11. It analyzes technical solutions and environmental impacts on Ukraine and Kazakhstan. The study emphasizes engineering solutions such as energy-efficient systems, waste management, and transportation infrastructure, along with environmental impacts involving carbon footprints, greenhouse gas emissions, and resource consumption like water and energy. It uses a comparative approach between the Ukrainian cities of Kyiv and Lviv, and Astana and Almaty in Kazakhstan. The study utilized both multiple linear regression and correlation matrix analyses, and findings show that energy-efficient systems, resource consumption, and waste management practices have a significant correlation with carbon footprint output for both countries. Furthermore, Ukraine’s engineering solutions highlight resilient post-conflict recovery efforts to promote sustainable urban infrastructure, while Kazakhstan’s focus is on innovation, driven by urbanization needs stemming from regional imbalances, uneven population distribution, and migration.
