Disrupting the Future: Great Ideas for Creating a Much Better World

In 2052: A Global Forecast for the Next 40 Years ,Jorgen Randers draws on his own experience in the sustainability area, global forecasting tools, and the predictions – included in the book as ‘Glimpses’ – of more than thirty thought leaders to guide us through the future he feels is most likely to emerge towards the middle of the century. At a meeting of 25 of the ‘Glimpse’ authors in Cambridge in October 2013, each participant was invited to present a ‘great idea’ (or thought, or development or fact) that they believed could improve on world developments over the next forty years. This book is the result of this process and is a remarkable collection of ideas and proposals by a diverse set of thought-leaders, each of which has responded in their own creative way to Jorgen Randers’ concluding challenge in 2052: ‘Please help me make my forecast wrong. Together we could create a much better world.’ Buy the book / Buy the e-book.

CSR 2.0: Transforming Corporate Sustainability and Responsibility

The book examines the evolution and current state of corporate social responsibility (CSR), using a five-stage maturity model: defensive, charitable, promotional, strategic (all CSR 1.0) and transformative CSR (CSR 2.0). Reasons are given why CSR 1.0 approaches have failed to have any significant impact on the most serious global social, environmental and ethical challenges. The emergent CSR 2.0 is explored in detail by elaborating on five principles underlying the new approach, including: creativity, scalability, responsiveness, glocality and circularity. A four-part DNA Model is also introduced, covering value creation, good governance, societal contribution and ecological integrity, which provides the basis for defining and measuring CSR 2.0. Finally, a 70-question CSR 2.0 self-assessment diagnostic tool developed by the author is presented, with sample data to show how the tool can be used for future research and practitioner application.

The Age of Responsibility: CSR 2.0 and the New DNA of Business

Traditional corporate social responsibility (CSR) approaches have failed, leaving business stuck in the Ages of Greed, Philanthropy, Marketing and Management. Using Web 2.0 as a metaphor, Visser shows how business needs to radically transform if we are to ever reach a true Age of Responsibility. The required systemic approach is dubbed CSR 2.0 and characterised by five key principles: creativity, scalability, responsiveness, glocality and circularity. Citing more than 300 cases to illustrate ‘the good, the bad and the ugly’, the book describes how the new DNA of business is fast being decoded in the areas of value creation, good governance, societal contribution and environmental integrity. Having set out a compelling vision of the future, Visser describes how to get there by exploring change at the societal, organisational and individual level. Buy the paper book / Buy the e-book.

Corporate Citizenship in Africa: Lessons from the Past, Paths to the Future

Corporate citizenship is enmeshed in the debate about Africa’s future. Africa is the continent where the social needs are greatest and where the benefits of globalisation have been least felt.

This unique collection for the first time brings together in one publication the critical debates, perspectives, experiences and success stories in the emerging field of corporate citizenship in Africa. This publication marks a change in the tide – a groundswell towards a more vigorous debate and robust research agenda on corporate citizenship in Africa. Buy the paper book / Buy the e-book.

Business Frontiers: Social Responsibility, Sustainable Development and Economic Justice

Business operates at the frontiers of society – seeking out new territories to explore and exploit, imagining fresh new ways to meet age old needs, innovating the artefacts that become the legacy of civilisations, reinventing the rituals which shape acceptable social behaviour, and changing the way we spend our precious time. But what happens when the landscape itself changes? As the world globalises, power is shifting – from the plush boardrooms to dusty streets, from the financial market casino to the internet connected community, from the annual general meetings to the mass activist campaigns, from the office towers of the North to the crowded pavements of the South. Business faces its greatest challenge yet. Confronted with the triple imperatives of social responsibility, environmental sustainability and economic justice, business will need to adapt or die. Buy the paper book / Buy the e-book.

Beyond Reasonable Greed: Why Sustainable Business is a Much Better Idea

In an analysis of the principles driving modern business, this book demonstrates that the predatory behaviour of the lion is symbolic of the way most companies are run today. But the world cannot go on like this. They argue strongly for an alternative and more positive vision involving sustainable business in both a social and an environmental sense. In order to achieve this, companies will need to change – as they call it ‘shape-shift’ – from the tooth-and-claw logic of lions to the more caring, holistic philosophy of the elephant. The conclusion of the book is that multilevel shapeshifting is required for sustainability. Apart from corporate transformation, it is up to governments on the one hand and each and every one of us as individuals on the other to adopt the persona of an elephant in order to pass on a worthwhile heritage to our children. Buy the paper book / Buy the e-book.

The Poetry of Business: A CEO’s Quest for Meaning

It was time to leave. A bitter-sweet time. The CEO felt sadness, but also contentment. The business he had conceived and birthed and nurtured was mature enough to stand on its own feet now; to live out its own life. Ironically, the way he saw it, the company was not the legacy he was leaving at all. The real value was in the way in which the business lived and breathed and kept its people engaged and passionate. That was the real gift he had given them. And that was why he was leaving behind his scruffy notebooks in the boardroom cabinet – those dog-eared, tea-stained pages on which, over the years, he had jotted down his ideas. Scrawled untidily were the lessons he had learned along the way: about how to make a business ‘fit for human beings’; about how to survive in commerce and still sleep soundly at night; about how to create a company that served society, instead of the other way around. So many thoughts … Buy the paper book.
