We had the absolute pleasure of hosting Lisa Annabel Ellis from YellowYellow as a panelist at the Net Impact Schulich Annual Conference, and it was truly one of the highlights of our event. Lisa brought such depth, clarity, and thoughtfulness to the discussion—sharing not only her rich expertise in ESG and sustainability strategy, but doing so in a way that truly resonated with our students. Her ability to distill complex concepts into real-world insights was incredibly impactful for everyone in the room. You could tell she genuinely cared about driving meaningful change and empowering the next generation of leaders to think critically about sustainable business. YellowYellow is clearly a reflection of Lisa’s values—purpose-driven, insightful, and grounded in action.
