Aligning AI and Data with Responsible Practice

At Cleartelligence, we help clients align their data and AI strategies with responsible, sustainable, and scalable practices. Through purpose-driven consulting, we’ve partnered with organizations to modernize data platforms, optimize Snowflake and cloud costs, strengthen data governance, and embed ethical principles into AI workflows. This session will share practical examples of how consulting grounded in transparency, accountability, and long-term resilience can deliver both business value and lasting impact—proving that responsible data and AI practices aren’t just aspirational, they’re achievable.

Paving the way to Sustainable and Responsible AI

Join us on our sustainability journey at Rackspace, where we transformed our formative sustainability commitments into actionable steps, resulting in measurable progress towards our CO2 emission reduction goals. We’ll discuss how implementing appropriate governance —embedding sustainability within the organisation from the top down—enabled us to prioritise sustainability initiatives across the organisation.  Additionally, we will explore how these efforts informed our approach to AI, under the FAIR banner, including our Sustainable and Responsible AI Principles, which ensure that AI adoption is symbiotic, secure and sustainable by design for our internal operations and our customers.

10:50 am - 11:15 am

From Code to Community: Innovating Responsibly in the Age of AI

This session explores how we can architect IT systems that are not only scalable and efficient but also responsible and regenerative. We share our Green Ops Framework, grounded in Responsible Computing, Fin Ops principles, and empathy-based design thinking, to showcase how sustainability can be embedded in every layer of architecture - from automation to user experience. Through real-world wins like eliminating postal items and reducing legacy systems emissions - we'll show how thoughtful innovation can lead to measure environmental and social impact. At the heart of this journey is a growing community of practitioners who believe that the future of IT must be built collaboratively, one line of code and one act of empathy - at a time.
