The critical issues facing the world are making their way to the top of the business agenda: carbon emissions, inequality, data privacy, plastics, and many more. That means the new generation of business leaders coming to the fore today - and tomorrow - need to be equipped to rise to the new demands being made on them. In a time of growing crises, it takes a new mindset to lead a business - we call it the activist mindset. Most people feel powerless when they look at the problems facing the world - but if you're the leader of a big business, you're not powerless. This book shows how thinking like an activist can animate your leadership, and have a transformative impact - for yourself, for your businesses, and for broader society.
