“Technology, Humanity, and the Climate Imperative: Engineering a Sustainable Future”

 Climate change is no longer a distant threat—it is a defining reality shaping our planet, economies, and societies. This keynote invites participants to take a bird’s-eye view of the interconnected forces driving this transformation and to explore how technology, data, and global citizenship can converge to create a sustainable future. We begin with critical observations on climate change and its cascading impact on population dynamics and economic resilience. From there, we examine the evolving energy mix, where renewable sources are not just alternatives but imperatives, demanding innovation in materials, transistors, and processors that power both ICT and solar technologies.

As we enter the data era, ICT systems and smart IoT solutions are unlocking unprecedented sectorial benefits—from MedTech and HealthTech to agri-food and construction—while enabling biodiversity and sustainability at scale. These advances are not merely technical; they represent a societal shift toward intelligent, resource-efficient ecosystems. Drawing on decades of experience in sensor technology development and active engagement with global organizations, this talk will challenge academia, industry, and policymakers to embrace technology uptake as a catalyst for systemic change. Ultimately, the question is not only how we innovate, but how we become true global citizens—responsible stewards of the planet we share, and architects of a future where digital intelligence and clean energy work hand in hand to safeguard life on Earth.
