The document discusses the Australian Low Carbon Transport Forum's efforts to estimate the emission reduction potential within the Australian transport sector. It includes contributions from various experts, outlines a series of workshops aimed at collecting expert input, and highlights key findings on emission abatement strategies. The document emphasizes the importance of addressing uncertainties and challenges through quantification of emission reduction measures to inform policies and practices.

3. The Australian Low Carbon Transport Forum
(ALCTF)
Estimating emission abatement potential for Australian
transport
What is the maximum feasible emission
reduction across the transport sector?
What are some of the measures, policies and
research directions capable of delivering the
desired future outcomes?

4. ALCTF - initiated by project secretariat from:
ARRB Group - Caroline Evans
BITRE - David Cosgrove, David Gargett
CSIRO - Paul Graham

5. ALCTF process:
Series of workshops – elicit expert input
Assessment of possible options for reducing transport
emissions – identify any uncertainties or challenges
Quantification of emission abatement potential – both for
each option individually and as part of an aggregate set
of measures
