As AI becomes an integral part of business and society, organizations must navigate the intersection of ethics, sustainability, and technology. AI governance is no longer a compliance checkbox—it is a strategic necessity that impacts innovation, trust, and long-term business success. This conference will explore how leaders can move from a traditional ROI mindset to a Holistic Return on Ethics (HROE) framework, demonstrating how ethics can drive value creation, risk mitigation, and sustainable growth.

Optimizing, making more effective, more efficient is one the goals for both IT and Green IT, but it won’t be enough for the ecological transition. Moving away from a volume logic is the only way out for a sustainable systemic transformation that truly takes into account planetary boundaries.

Booking a taxi, ordering groceries online, or finding information about elections — simple tasks for many, yet they can turn into a real challenge for others. In this talk, Ibrahim, who is blind, shares firsthand experiences navigating the web with a screen reader. Through real-life examples, he sheds light on the barriers many still face in the digital world. As a seasoned digital accessibility expert, switching from personal perspective to professional insight, he then explores the practical solutions we can implement to build a more inclusive web. Whether you're a designer, developer, or decision-maker, you'll gain a clear understanding of your role — and your legal responsibilities — in making digital accessibility a reality for all.
