On April 28, 2026, Kovács Szabolcs, founder of GreenSense and sustainability podcaster, delivered an English-language lecture at our University on the fundamentals of the circular economy and the importance of sustainable business development. Invited by the Kerpely Antal College for Advanced Studies and the UoD-Hungarian Startup University Program, the speaker also emphasized the role of individual responsibility in driving positive change. Addressing more than 30 students online and in person - including startup founders, future business leaders and professionals - he introduced the “4E” principle (Enable, Encourage, Engage, and Exemplify) highlighting how shaping environments and motivations can support more sustainable behavior. Through practical examples, he demonstrated how individuals, organizations and communities can contribute to more sustainable operations and initiatives.
