Top Ten Scientific Advances in China’s Eco-environmental Sector Unveiled on World Environment Day
According to official release from the Eco-environment Industry-University Consortium under the China Association for Science and Technology, the launch event for the 2025 Top Ten Scientific and Technological Advances in China’s Ecological Environment was held in Beijing on 5 June 2026, coinciding with World Environment Day.
The ten landmark technological achievements cover a wide spectrum of environmental research and engineering applications. They include climate adaptation and resilience enhancement strategies for global wind and solar power systems, mechanisms behind hydrometeorological risks facing energy systems amid climate change alongside targeted regulation solutions, core technologies to mitigate barriers in acidic southern soils and boost crop yields, research on nitrogen-phosphorus cycling and its interaction with carbon cycling in alpine grassland ecosystems, newly identified spatial mechanisms sustaining forest biodiversity, analytical frameworks detailing climate change impacts on lake ecosystems, non-destructive remote sensing equipment and monitoring techniques for grassland biodiversity, formation pathways and prevention approaches for compound extreme events combining heatwaves and surface ozone pollution, advanced deep nitrogen removal technology featuring shortcut denitrification and anaerobic ammonium oxidation for municipal wastewater, as well as verification of thorium-uranium conversion in molten salt reactors and innovative thorium resource utilisation schemes.
These landmark research outcomes embody the collective efforts of numerous researchers and mark major breakthroughs in low-carbon cutting-edge technologies, coordinated multi-pollutant control, ecological restoration and carbon sink expansion. The research outputs support national strategic priorities and demonstrate China’s commitment to global sustainable development agendas on the international stage.
Technological innovation acts as the most powerful driving force to tackle environmental hurdles and deliver sustainable development goals. The selected advances represent the latest research milestones in China’s eco-environmental science and technology, and illustrate the country’s systematic capacity to tackle intricate environmental challenges. These technological breakthroughs will accelerate overseas dissemination, delivering robust technical backing for the Beautiful China initiative. Platforms including the Belt and Road Initiative Green Development Partnership will facilitate experience exchange and shared technological benefits with economies across the globe, particularly developing nations.
Candidates for the 2025 ranking were put forward by members of the Chinese Academy of Sciences and Chinese Academy of Engineering, consortium affiliates, universities and specialised research institutions. Shortlisting was completed by leading strategic scientists, before a final voting round carried out by a jury consisting of twelve academicians from the two national academies. This annual selection activity enters its seventh consecutive cycle in 2026.
The selected projects mirror the latest frontline trends within China’s eco-environmental technology sector. The published list fosters technological innovation in environmental disciplines, encourages continuous fundamental ecological research, raises public environmental awareness and nurtures a nationwide innovation-friendly climate. These technological advances deliver solid technical underpinnings for national ecological conservation and ecological civilisation construction.
