As the environment becomes more fragile, existing transportation networks are more and more strained. Issues such as food miles and embodied energy in goods and products will become far more significant. Personal carbon quotas are likely to force a re-evaluation of our current lifestyles and single trips will carry greater levels of expectation. Casual long distance travel may be socially decried. Edge Futures are a series of six books that explore the impact that climate change will have on different aspects of our lives in the future. They are available to order as individual titles or as a complete set. The Edge is an innovative and creative think-tank, sponsored by building industry professions, that seeks to stimulate public interest in policy questions that affect the built environment and to inform and influence public opinion.
