Sustainability is now a buzzword both among professionals and scholars. However, though climate change and resource depletion are now widely recognized by business as major challenges, and while new practices like 'green design' have emerged, efforts towards change remain weak and fragmented. Exposing these limitations, Design Futuring systematically presents ideas and methods for Design as an expanded ethical and professional practice. Design Futuring argues that responding to ethical, political, social and ecological concerns now requires a new type of practice that recognizes design's importance in overcoming a world made unsustainable. Illustrated throughout with international case material, Design Futuring presents the author's ground-breaking ideas in a coherent framework, focusing specifically on the ways in which concerns for ethics and sustainability can change the practice of Design for the twenty-first century. Design Futuring - a pathfinding text for the new era - extends far beyond Design courses and professional practice, and will also be invaluable to students and practitioners of Architecture, the Creative Arts, Business and Management.
