The environmental impacts of the Victorian transport system are
significant and include the production of greenhouse gas emissions,
other air pollution and noise.
Minimising these impacts has been a legislated objective since
2010, but it is clear that the Department of Transport, Planning
and Local Infrastructure (DTPLI) has not adequately addressed this
when developing the state's strategic transport and land-use
planning framework (the strategic framework)—consisting of Plan
Melbourne, Victoria—The Freight State and the state's eight
regional growth plans.
During the strategic framework's development, DTPLI did not
provide the government with any advice:
- about how proposed
strategies would address the environmental impacts of the transport
- proposing defined
statewide objectives or targets for reducing transport‑related
greenhouse gases and other emissions and for limiting the effect of
In the absence of DTPLI developing a comprehensive monitoring
and reporting framework with clearly defined expected environmental
outcomes and performance measures, the framework currently remains
aspirational in this regard.
Across the three agencies examined, VicRoads has the most
comprehensive strategy for managing environmental impacts, and this
is a model for what should exist on a portfolio-wide basis.
Public Transport Victoria (PTV), on the other hand, does not
have a dedicated plan and its performance in this regard has
declined since our 2012 audit, Public Transport
Performance. Specifically, PTV did not progress options
identified by the former Department of Transport on how to improve
public transport's energy consumption and greenhouse gas emissions.
Further, the quality and availability of publicly-reported
information on public transport's environmental performance has
