'What does it mean for the environment?' is a strategic corollary of almost any significant business decision today, and companies must take seriously their responsibilities to regulators, customers, employees and the wider society. A Thousand Shades of Green is aimed at business leaders in need of a clear understanding of the key corporate environmental challenges and the insight and vision to meet them - imperatives such as engaging stakeholders and developing partnerships, understanding the policy-making process, forming corporate responses and drafting environmental management strategies - with the promise of genuine competitive advantage for their companies. Drawing on their extensive consultancy experience with some of the most progressive companies around the world, the authors examine why and how businesses must confront the rapidly developing agenda set by environmental constraints and social and regulatory pressure. They identify the corporate environmental challenge with that of change management and advocate a recognition that there is no single strategy or endgame applicable to all companies - there are a thousand shades of green. Only by pursuing thorough, reflective, consistent, competitive and proactive strategies will businesses be able to avoid being embroiled in costly and complex reactive approaches.
