Environmental Science is an integrated science using the basic knowledge and skills of applied biochemistry, biology, and chemistry to assess and resolve environmental problems. In response to the growing public concerns about the environmental protection and conservation issues, the University established the Environmental Science Programme in 1994. We foster our students with training in ecology, environmental chemistry, pollution control, waste management, biodiversity, conservation, toxicology and health, energy research, environmental impact assessment, and policy development. Our body of lecturing staff comprises professors from the School of Life Sciences and Department of Chemistry, as well as other professionals from related disciplines.

Career Prospects

More than half of our graduates have directly involved in environmental related careers after graduation. They work in government departments, consulting firms, green groups, and commercial sectors focusing on various aspects of environmental issues, ranging from green purchasing, carbon audit, to environmental impact assessments and tree management. Some of them have stayed in academia by pursuing postgraduate studies or as researchers, whilst some others have joined the education sector as teachers, or business sectors as administrators or marketing officers. Our graduates could become environmental professionals by joining the HKIQEP (Hong Kong Institute of Qualified Environmental Professionals).

Alumnus Sharing

Claudia LAU

The Environmental Science Programme has offered me interdisciplinary knowledge related to the environment, including environmental chemistry, toxicology, environmental impact assessments as well as environmental protection and management. The knowledge and skills that I have learnt in lectures, laboratory classes and field studies are intriguing and invaluable. In the final year of my undergraduate study, I have joined an internship programme which offered me a valuable opportunity to participate in various environmental education projects to deliver conservation messages to youngsters. Besides, I also joined a two-week field study in Kazakhstan to perform ecological investigation in the West Altai Nature Reserve and Charyn Canyon National Park. I find my four year university life at CUHK rewarding and eye-opening. The knowledge and experience that I have obtained are invaluable to my future development.
