A decade ago at the Sustainable Brands conference, Freya Williams launched Green Giants, the landmark book that examined companies merging social responsibility with profitability. These pioneers collectively represented more than sixty billion dollars in revenue—often outpacing their conventional peers in growth and profit margins. The book offered a blueprint for building sustainable businesses while achieving financial success. Ten years later, Freya returns to the SB stage to reflect on those original green giants, and to explore what it takes to scale sustainability into true competitive advantage in 2025 and beyond, and the next era of billion-dollar opportunities for brands that lead with purpose.
