BTRE Transport Colloquium Canberra 13-14 June 2007 Cars, Trucks, Planes: What will drive them in the future? Headlines: (1) • Biggest increase in Australia’s emissions since 1990 is private transport – Increased 29% since 1990 Headlines: (2) • Public transport in crisis – “Transport congestion choking Melbourne” -- The Age – “Fuel price drives commuters onto buses and trains” -- SMH • What do these problems have in common?

California 58% Greenhouse gas emissions Australian transport GHG must not be confused with Air Quality! Air quality is an issue in urban areas (particulate carbon, mostly from diesel) GHG emissions are a national/global issue Methane (CH4) and nitrous oxide (N2O) also need to be considered. Change in emissions profile Why the increase in GHG for cars? 2NO 2NO2 N2 + O2 N2 + 2O2 N2O Nitrous oxide (N2O) is 310 times as potent as carbon dioxide And there’s a second reason! Engines have improved in fuel efficiency 20% over the past 20years, However this has been offset by growth in vehicle size Road Vehicles Australia Passenger Vehicle Fuel type 10000000 9000000 8853925 Transport Fuel Mix 25000 19962 8000000 20000 7000000 52% 6000000 14461 15000 5000000 4000000 37% 10000 3000000 2000000 1000000 198615 152912 4253 5000 784 11% 0 0 Petrol Diesel 2002 LPG Other Petrol ADO 2003/04 LPG The Technology Progression for Australia? Oil based transport system Hydrogen based transport system Biofuels from current agriculture Ethanol If we used all the crops (sugar, molasses, wheat, coarse grain) suitable for making ethanol and converted them to fuel it would only replace 75% of our petrol. (If we stopped exporting grain we could replace 25% of our petrol) Biodiesel If we used all the crops (canola, cottonseed and others) suitable for making diesel and converted them to fuel we could replace only 10% of our diesel usage. Conclusions: Ethanol could support E10 for most of Australia Urgent research is needed into next-generation biofuel technologies.

With aXcess Australia, a series hybrid vehicle.

Could we achieve substantial emission reductions? 1970 Road deaths 3,798 Number of vehicles 3.74 million Could we achieve substantial emission reductions? 1970 2006 % Change Road deaths 3,798 1605 -58% Number of vehicles 3.74 million 13.49 million +260% Could we achieve substantial emission reductions? 1970 2006 % Change Road deaths 3,798 1605 -58% Number of vehicles 3.74 million 13.49 million +260% Death rate Per 100,000 101.5 11.9 -89% 89% reduction in 36 years!
