Can transportation and land use planning mitigate the rate of global climate change?
1. We must respect the laws of physics, economics, politics and household behavior.
2. What is possible is not always probable; what is improbable is not necessarily impossible.
3. Public policy typically seeks to accomplish a goal while simultaneously preserving the status quo.
4. American preference is to look to technology for solutions that preserve the status quo.
5. Significant technological change comes unexpectedly and carries unintended consequences.
6. Household behavior is remarkably consistent – if observed at the level of core relationships.
