Emissions and economic modelling of NSW road and rail freight

This research aims to model the impact of various policy levers on carbon emissions from road and rail freight.

Freight train in motion

The research also aims to identify the economic benefits (including value of CO2 emissions reductions and public health effects) that will result from decarbonising the freight sector in NSW.

The research will be delivered by Swinburne University of Technology and the University of Queensland.

Background

The transport sector in NSW is the second largest contributor to the state’s greenhouse gas emissions. Road freight in particular is a significant contributor to the sector’s emissions and is expected to grow as a proportion of total emissions. Transport for NSW (TfNSW) is committed to supporting the reduction of emissions across the freight sector and to achieving the NSW government’s commitment to net zero emissions by 2050. This study is focused on road freight vehicles that are >4.5T, as this is a segment that poses the most emissions reduction opportunities, but will also assess the impact of mode shift to rail.

Achieving this target will require government and industry to work together to identify and remove barriers to transport emissions reductions, and to embrace innovative, agile and outcome-focused policies and interventions. TfNSW is working closely with partners to progress the net zero freight emissions policy.

At present, there are opportunities to integrate new data and insights to address uncertainties and improve the granularity of existing freight transport and emission projections, and to address knowledge gaps regarding the most effective and cost-effective policy levers and interventions to reduce NSW freight emissions and realise positive social and economic benefits.

This research will help develop a robust evidence base to support the development of the Transport for NSW (TfNSW) Net Zero Emissions Freight Policy through emissions and economic assessments up to 2061.

Objectives

The research proposed in this study aims to develop a robust evidence base to support TfNSW‘s development of policy levers to support emissions reductions road freight. This will be achieved through delivering robust and granular NSW-wide freight transport (vehicle-kilometre travelled, VKT) and associated emission projections per heavy vehicle sector out to 2060 and credibly assessing identified policy interventions to accelerate emission reductions from NSW road freight.

This assessment will include an analysis of the technical feasibility of these policy interventions; present socio-economic and environmental impacts of potential measures; quantitative modelling of VKT and emission reductions out to 2061; and economic assessment of key levers and interventions (packages of policy levers and interventions).

The study will assess the technical feasibility of policy interventions as proposed by TfNSW. These proposed interventions are informed by findings from industry consultations undertaken by TfNSW focused on barriers, opportunities and issues in transitioning to low and zero emissions vehicles. These interventions are also based on research and known successful interventions that have been pursued by other jurisdictions to reduce emissions in the freight sector. 

Following the analysis of the technical feasibility and socio-economic and environmental impacts of these potential measures, (packages of) policy levers and identified interventions will be modelled.

Specifically, the research will aim to achieve the following objectives:

  • Model baseline (DPE’s freight emissions projections of current policy settings) emissions and select economic outcomes out to 2061, improving the robustness and granularity of road freight emission projections to facilitate the credible modelling of interventions. 
  • Model the impacts of identified policy levers (packages of policy levers) on road freight VKT and emissions reduction of different sectors and vehicle types (rigid and articulated), including economic assessment, both to:
     
    • Economic cost/benefit  – in the form of monetary expendidure and savings to government; and 
    • Society – in the form of monetised health, and where possible, environmental and wellbeing, impacts of lower emissions; and likely costs of transition for freight operators. 
  • Undertake economic assessment of the proposed policy interventions, including identified assessment of best practice suite of policy levers.
