This course explores sustainability in business, urban, and rural contexts through an economic lens. It covers corporate sustainability, urban-rural development, and key issues related to the four pillars of sustainability: economic, social equity, environment, and well-being. Students engage with case studies, guest speakers, and discussions to critically examine the entrepreneurial case for sustainability, enhance teamwork and communication skills (oral and written), and analyze how sustainability integrates into corporate strategy, urban planning, and geographic development. They will also analyze sustainability metrics such as the Sustainable Development Goals (SDGs) and social progress indicators, along with policy debates and challenges in the Global South. The course emphasizes real-world applications, equipping students with the skills to assess and address sustainability issues across industries, cities, and economies within different spatial contexts. Prerequisites: BUEC 211 or ECON 281.
