Professor Phoebe Koundouri’s keynote speech at Climate Action 2025, organized by the Hellenic Society for the Protection of Nature (HSPN)—the first environmental NGO in Greece with more than 70 years of continuous activity—is now available online together with the full event recording.
In her intervention, titled “War and the Environment: Geopolitical Instability and Its Impacts on Biodiversity,” Professor Koundouri examined how today’s multidimensional crises—climate change, environmental degradation, economic and social instability, demographic pressures, and geopolitical conflict—accelerate biodiversity loss and disrupt ecosystems. She also emphasized the central role of the Sustainable Development Goals (SDGs) as the most comprehensive global framework for addressing these interconnected challenges, highlighting the urgency of integrated tools that bridge science, technology, finance, and implementation capacity.
Professor Koundouri further presented the systems-based methodologies developed at Ae4ria – Alliance of Excellence for Research and Innovation on Aephoria, which bring together scientific evidence, technological innovation, financial instruments, and stakeholder engagement to support sustainable transitions. These methodologies also inform the UN Global Sustainable Development Report 2027, where she serves as Chief Scientist.
Professor Koundouri extends her sincere appreciation to the organizers for the invitation.
