This course equips students to engage in well informed and rational debates on how to develop our societies in the long run. The first half of the course begins by positioning energy and environmental policy within the broader context of sustainable development. Notably, it helps cultivate an understanding of the problems and prospective solutions associated with fostering a transition away from carbon-intensive energy technologies, which consume finite resources. The second half of the course introduces students with existing energy and environmental policies, implemented by governments in the world, including Hong Kong and mainland China. The overall aim of the course is to cultivate a working understanding of the realities, issues, solutions and applied policy challenges that one faces when seeking to develop a sustainable energy and environmental policy.
