About
The 20th National Environmental Conference for Doctoral Students
in Conjunction with 2026 Asian Universities Alliance Postgraduate Academic Forum
The 20th National Environmental Conference for Doctoral Students (hereafter referred to as “NECDS”) is an international conference focusing on environmental and related disciplines. Adhering to the mission of “Fostering Innovation through Exchange and Collaboration, and Achieving Mastery through Comprehensive Learning”, it serves as a high-level platform for doctoral students in environmental and related fields to discuss edge-cutting theories and technologies in environmental science and engineering.
Over the past nineteen years, NECDS has consistently grounded in the demands of pollution control and environmental quality improvement, dedicated to nurturing high-caliber environmental talents. Complementing traditional doctoral education, it offers a supplementary educational experience featuring mentorship from renowned experts and peer interaction. By breaking down disciplinary silos in the environmental field, the conference has fostered cross-disciplinary and cross-media innovation. Centered on doctoral students, NECDS has established an exchange platform characterized by student-led organization and in-depth participation. To date, NECDS has been successfully held for nineteen sessions, attracting over 5,700 attendees. It has gained widespread recognition from scholars, postdoctoral researchers, and graduate students in the environmental field worldwide, evolving into one of the largest academic exchange platforms for doctoral students in the environmental field to share ideas, broaden disciplinary horizons, and cultivate academic friendships.
The 20th NECDS will take place in May 2026. This year's conference is jointly hosted by Tsinghua University, the Chinese Society for Environmental Sciences, and the State Key Laboratory of Regional Environment and Sustainability, organized by the School of Environment of Tsinghua University, and supported by the Asian University Alliance, the Engineering Environmental journal, and Hach Company.
