Paul Polman, former CEO of Unilever, led a dazzling career in consumer goods, from Procter & Gamble to Nestlé to the British multinational. His experience fending off a hostile takeover bid taught him that the doctrine of shareholder capitalism is wrong. He believes there’s a better way of doing business, one that embraces all stakeholders — not just stockholders — and improves the environment. He cofounded the consultancy IMAGINE to further sustainable goals, and he shares his advice for the next generation of leaders. With Andrew Winston, Polman wrote the new book “Net Positive: How Courageous Companies Thrive by Giving More than They Take”.
