Businesses today need to balance the pursuit of profit with the  needs of growing numbers of people on a planet under pressure.  While sustainability programs, government action, and nonprofits  are all parts of the solution, a growing contingent of  forward-looking leaders recognizes the real challenge: a  fundamental shift in the nature of commerce. CEOs and other leaders  must focus the practice of business on social, environmental, and  economic benefitnot only because it will make the world a  better place, but because it will ensure lasting profitability and  success in the business climate of tomorrow.  The Breakthrough Challenge is an inspiring call-to-action  and guide for this transformation, based on the work of the B Team,  a major initiative uniting leaders in sustainability. As founding  members of the B Team, John Elkington and Jochen Zeitz map out  their agenda for change. The most important goal for businesses  must be redefining the bottom line to account for true long-term  costs throughout the supply chain. To achieve this, leaders must  rethink everything: what counts on balance sheets, how to incentive  performance, who does what in the C-suite, and even what inspires  us. The Breakthrough Challenge draws on over 100 exclusive  interviews to show this shift in action, sharing the pioneering  work of leaders such as Paul Polman, CEO of Unilever; Arianna  Huffington, founder and CEO of The Huffington Post; Peter  Brabeck-Letmathe, chairman of the Nestle Group; Linda Fisher,  pioneering Chief Sustainability Officer at DuPont; among many  others.    Change-as-usual strategies are not enough to move business from  breakdowns to breakthroughs. The Breakthrough Challenge  shows leaders how to achieve a true transformation and refocus the  definition of profitability on the lasting wellbeing of people and  planetfor the lasting success of their business.
