The Road Forward: Cost-Effective Policy Measures To Decrease Emissions From Passenger Land Transport is a comprehensive book that identifies and evaluates numerous policies for reducing passenger transport emissions on land, especially in urban areas. 

The Road Forward

The reduction of transport emissions has become a key priority for many cities and towns, particularly as we seek effective action to mitigate the disastrous effects of global climate change. Transport emissions reductions are also essential to improve air and water quality, promote human health and wellbeing, support urban livability and quality of life, and even enhance economic performance and competitiveness.

This 165-page book is aimed at helping to expand the range of solutions to the problem of transport emissions and provide more modest-cost alternatives at the local level. It is not looking for "silver bullets" that may never come, but rather, for "silver buckshot"—that is, multiple tools and strategies available now that can not only reduce emissions but improve the quality of life for the residents of cities and towns. It aims to assist in the evolution of a new generation of transport and of its surrounding land use that is safer, cleaner, more walkable, more transport-supportive, and offers a greater variety of choices in mobility.

The Road Forward: Cost-Effective Policy Measures to Decrease Emissions from Passenger Land Transport, was written by Michael W. Mehaffy, Jorge Rogat, Todd Litman, Begonia Gutierrez Figueroa and Talat Munshi and published by the Centre for the Future of Places, KTH Royal Institute of Technology Copenhagen Centre for Energy Efficiency, UNEP DTU Partnership, in Association with Sustasis Press. Available free as a PDF file at or, and hard-copies can be ordered through Amazon Books.

Density and Driving: A Second Look

A common argument against more compact housing is that increased population density will only reduce vehicle miles traveled at moderate levels of density, as opposed to very low-density and very high-density areas. But this might not be so.
