Analysis of Transportation-Sector Policy Selection and Policy Preference Expressed in State Climate Action Planning Processes

摘要

INTRODUCTION In order for greenhouse gas reduction (GHG) strategies to be effective in a practical sense, they must meet a number of requirements beyond simply demonstrating an emissions reduction potential on paper. In particular, strategies must be politically acceptable to the communities and interest groups affected by them. In the transportation sector, a great many policies have been proposed which show great promise as paths to energy efficiency and lower emissions, but face significant political-acceptance hurdles. Strategies which price road use or which divert significant travel from single-occupancy vehicles to more efficient modes such as transit are two such effective but politically challenged approaches. Understanding which policies attract more political support (or, at a minimum, less political opposition) is important in order to design overall GHG-reduction approaches which have a reasonable prospect of actual implementation.
