In Australia in 2014, our diesel demand equaled 22,900,000,000 litres of fuel. According to the Australia’s National Greenhouse Accounts (NGA) 2.7kg of CO2 is emitted for every litre combusted in an engine. So in terms of Australia’s 2014 consumption of diesel, we emitted 61,787,406,000kgs or 68.8 million tonnes of CO2.
The use of biodiesel blended fuels is a vital tool in our fight against climate change and global warming. Biodiesel blended fuels can significantly reduce our greenhouse gas emissions over their entire lifecycle, from production through to use in the vehicle.
The NGA also states that one litre of biodiesel reduces net emissions of CO2 by over 95%, so one litre of biodiesel will save approximately 2.5kg of CO2.
So by replacing just 20% of the diesel consumed in AUstralia with Biodiesel (by using B20), we could reduce our emissions and save about 11.8million tonnes of CO2 per year.
However at the moment, we don’t use B100 blends. If all heavy vehicles were using B20 blends only, our emission savings would be in the vicinity of 10million tonnes a year. By 2020, by which time our freight task is expected to reach about 25 gigalitres of diesel consumption per year, we would be saving about 45 million tonnes per year if we converted completely to B100.
