Jet fuel derived from a type of mustard plant can replace the petroleum-based aviation fuel to reduce carbon emissions by up to 68 per cent, according to a study led by an Indian-origin scientist in the US. The research estimated the break-even price and life cycle carbon emissions of the sustainable aviation fuel (SAF) derived from oil obtained from Brassica carinata, a non-edible oilseed crop.


  1. The researchers noted that the aviation industry emits 2.5 per cent of all carbon dioxide emissions from the US and is responsible for 3.5 per cent of global warming.
  2. Carinata-based SAF could help reduce the carbon footprint of the aviation sector while creating economic opportunities and improving the flow of ecosystem services across the southern region.
  3. Since carinata is grown in the 'off' season it does not compete with other food crops, and it does not trigger food versus fuel issues.
  4. Additionally, growing carinata provides all the cover-crop benefits related to water quality, soil health, biodiversity and pollination.
