Breaking Carbon Lock-In: Path Dependencies in Large-Scale Transportation Infrastructure Projects

Abstract

The central focus of this paper is to highlight the ways in which path dependencies and increasing returns (network effects) serve to reinforce carbon lock-in in large-scale road transportation infrastructure projects. Breaking carbon lock-in requires drastic changes in the way we plan future transportation infrastructure projects, and documentary evidence presented here from the metropolitan regions of Copenhagen, Denmark and Portland, USA, indicate that there may be a discontinuity in the system of automobility (Urry, 2004), thereby increasing the likelihood that such drastic measures may in fact be successfully realized. © 2014 Taylor & Francis.
