The Department of Environmental Science at the Royal University of Phnom Penh is proud to offer the first and leading Bachelor of Environmental Science programme in Cambodia. Officially established in 2001, the department has been at the forefront of environmental education in the country for over two decades. This four-year, 147-credit programme equips students with the scientific knowledge and practical skills to understand, manage, and protect the natural environment. Students progress from foundational sciences and mathematics in Year 1 through core environmental topics — climate change, biodiversity, air and water quality — before advancing into applied fields such as GIS, wastewater treatment, and environmental impact assessment. The programme culminates in independent research or a thesis, preparing graduates for careers in environmental management, policy, consulting, and sustainability across Cambodia and the region.
