Many city's current transport infrastructure is deemed to be inadequate for rapid population growth and projected urbanisation, driving an increase in the construction of more efficient and reliable transport infrastructure and networks. However, transport infrastructure projects have negative impacts on the environment, during both the construction and operational phases.Green wall technologies have become an increasing trend within urban areas to combat these impacts, however, their uptake has been limited. This study answers the question of whether green wall technologies are a suitable technology for instilling sustainability into major infrastructure projects. This was achieved by comparing available green wall systems, conducting interviews with leading industry professionals and developing a case study on the possible areas of implementation of green wall technologies within a major multi-billion dollar infrastructure project. The overall benefits and constraints are presented, with insights into how these systems may contribute to sustainability rating tools for infrastructure projects.
