Biodiesel Production from Canola in Western Australia: Energy and Carbon Footprints and Land, Water, and Labour Requirements

This study evaluates the energy and carbon footprints and land, water, and labor requirements of biodiesel production from canola in Western Australia (WA). The results show that canola-based biodiesel leads to limited energy profit and CO2 equivalent (CO2-e) emissions savings. Even when all byprodu...

description This study evaluates the energy and carbon footprints and land, water, and labor requirements of biodiesel production from canola in Western Australia (WA). The results show that canola-based biodiesel leads to limited energy profit and CO2 equivalent (CO2-e) emissions savings. Even when all byproduct are utilized, a relatively low output/input energy ratio of 1.72 and a CO2-e emissions savings of only 0.52 kg of CO2-e/L of biodiesel are obtained under the WA conditions considered in this study. A land requirement of 1.66 × 10−3 ha/L of biodiesel means that canola-based biodiesel seems to also be limited to

Also, there would not be enough net biodiesel to support the transport activities that are usually supported by diesel fuel in the WA transport sector, and no CO2-e emissions savings would be achieved from replacing diesel fuel by net biodiesel. Overall, canola-based biodiesel is not sustainable to replace a significant fraction of diesel consumption in the WA transport sector.
