Reflections From COP30: Insights for Environmental Science in the Asia-Pacific
Zuzanna Neziri, SETAC Asia-Pacific Executive Director
Charles C.C. Lee, a long-standing board member of SETAC Asia-Pacific, shared reflections from the 30th Conference of the Parties to the United Nations Framework Convention on Climate Change (COP30), which was held from 10–21 November in Belém, Brazil, during a session held on 11 December for students and early career researchers at the University of Newcastle, Australia. Drawing on his experience at COP30, Lee discussed global climate themes that align closely with environmental science priorities relevant to Australia, Singapore and the wider Asia-Pacific region.
Scientific Context for a Changing Climate
Lee opened by outlining the scientific basis of the climate crisis, noting long-term increases in atmospheric carbon dioxide and the influence of human activity on global temperature, precipitation and ecological stability. These climate-driven shifts affect chemical behavior, exposure patterns and ecosystem resilience – core areas of SETAC’s scientific scope, including ecotoxicology, environmental chemistry and ecological risk assessment.
Perspectives From COP30 in the Amazon
Hosted in the Brazilian Amazon, COP30 drew more than 60,000 participants from nearly 200 countries. Lee highlighted that the location brought global attention to biodiversity, rainforest protection and the integral role of Indigenous communities in land stewardship. Discussions centerd on topics such as fossil-fuel transition pathways, climate adaptation finance, sustainable land management and the importance of integrating diverse knowledge systems into environmental decision-making.
Lee noted that Brazil’s emphasis on connecting nature conservation with climate and energy strategies mirrors the interconnected nature of environmental science. This is especially relevant for researchers examining how ecological health, chemical fate and climate pressures intersect across rapidly changing environments.
Regional Implications for Australia, Singapore and the Asia-Pacific
Lee highlighted how issues raised at COP30 align with environmental challenges across Asia-Pacific. Australia and neighboring regions are already experiencing intensifying heat, changing rainfall patterns, sea-level rise and shifts in ecological integrity. These changes are altering environmental conditions across the region in ways that are being examined by researchers in environmental science.
He also pointed to the acute vulnerability of low-lying Pacific Island nations. Tuvalu, for example, faces significant long-term risks from sea-level rise, with potential impacts on coastal ecosystems, freshwater quality and habitat availability. These environmental pressures illustrate the need for robust scientific data to support adaptation planning and ecosystem resilience across the Pacific.
Lee additionally referenced Singapore’s national commitments at COP30, including adaptation planning, biodiversity protection and regional energy collaboration, all of which benefit from strong scientific foundations and cross-disciplinary research.
Supporting the Next Generation of Environmental Scientists
The University of Newcastle session offered students and early career researchers a valuable opportunity to connect global climate developments with local scientific questions. Lee underscored the importance of interdisciplinary research that integrates chemistry, ecology and sustainability science to support informed environmental management.
Advancing SETAC’s Mission
By sharing insights grounded in firsthand observation at COP30, Lee highlighted the essential role of evidence-based environmental science in understanding and responding to climate-driven change. His reflections reinforced SETAC’s mission to support rigorous scientific research and collaboration across Australia, Singapore and the wider Asia-Pacific region.
