The International Conference on Environmental Pollution and Ecological Environment Protection 2025 (EPEEP 2025) will be grandly held in Tianjin, which is a grand gathering of top experts, scholars, and industry leaders in the global environmental protection field. The purpose of this conference is to explore cutting-edge technologies, policy directions, and best practice cases in environmental pollution control and ecological environment protection, and to jointly seek effective strategies to address global environmental challenges. The theme of the conference is "Green Innovation, Harmonious Coexistence", emphasizing the coordinated promotion of environmental protection and economic development. During the conference, a series of high-level keynote speeches, thematic discussions, roundtable forums, and poster displays will be held to deeply explore hot topics such as climate change, water resource management, air pollution control, soil remediation, and biodiversity conservation. In addition, a special forum for young scientists has been established to provide a platform for young researchers to showcase their research results and interact with senior experts. Tianjin, as an important port city in northern China, has achieved significant results in promoting green development in recent years. Its practical experience in industrial emissions reduction, clean energy application, and coastal wetland restoration provides valuable learning opportunities for participants. Meanwhile, Tianjin's unique geographical location and abundant natural resources make it an ideal place to explore ecological and environmental protection issues in coastal areas. EPEEP 2025 is not only a platform for academic exchange, but also a bridge to promote international cooperation. The conference encourages researchers, engineers, decision-makers, and entrepreneurs from different countries and regions to share their knowledge and experience, and work together to achieve the United Nations Sustainable Development Goals. In order to enrich the participation experience, the organizers will also arrange on-site inspection activities, visiting some environmental demonstration projects and nature reserves in Tianjin, so that participants can intuitively feel the actual effects of local environmental protection work. This conference is of great significance in inspiring new scientific research inspiration, promoting technological innovation, and strengthening environmental protection awareness. We sincerely invite people from all walks of life to actively participate and discuss global environmental protection plans, and work together towards a greener and healthier future. Let us gather in Tianjin to witness and participate in this important international environmental event together.
