The predicaments of environmental impact assessment (EIA) for transport infrastructure: an examination of policy stagnation and progress

Purpose Environmental impact assessment (EIA) for transport infrastructure should consider geological constraints, legislative regulations, public policy and other strategic considerations. These considerations constraints that are often seen as the most challenging issues facing transportation planners critically reviewed. Subsequently, this study aims to evaluate enviromnetal impacts of civil infrastructure. Design/methodology/approach Using a mixed-method approach, examines EIA environmental statement (EIS) dimensions Findings Through development EIS framework infrastructure, paper found better enhance effectively calculate various indicator variables, hybrid approach method, known input–output analysis (IOA), needs be adopted. Knowing feasible cost breakdown is usually available within projects, it can concluded plausible add an (I–O) model into existing obtain results not only on-site effects but also off-site effects. Moreover, some benefits implementing IOA significantly improve completeness any conventional range quantifiable indicators, ability rank alternative options provide valuable overview indirect used streamlining audit. For these reasons, techniques could incorporated optional elements standards. Practical implications With input from Australian Bureau Statistics national I–O tables industry sector, research was able determine projects being considered what they worth. This enables us answer key questions dealing with EIAs on sector. This, in turn, assist planning through commissioning such projects. Originality/value The introduced will ultimately lead incorporation elements. findings thus aligning EIA. result improvements EIS,
