The growth in natural gas vehicles in Europe, the sub-continent and the Americas has been dramatic, with an objective of a nearly seven-fold increase by 2020 said Mr Kellett speaking at the APIA conference in Cairns after returning from the World Gas Conference in Buenos Aires, Argentina.

“Transportation contributes about 14 per cent of Australia’s greenhouse gas emissions and 50 per cent of this is due to cars.

“When you consider our major pipelines run and then consider where our major transportation corridors are situated, why aren’t we thinking more about natural gas vehicles?” Mr Kellett said.
