Context:  As part of efforts to reduce its carbon footprint, the Indian Air Force (IAF) is looking to fly an AN-32 transport aircraft modified to operate on 10% blended biodiesel for 200 flight hours in the next six months, Air Vice Marshal S. K. Jain, Assistant Chief of the Air Force (Maintenance Plans), said


  • The aircraft took flight on biodiesel blended with aviation turbine fuel (ATF) for the first time in December 2018.
  • So far, an AN-32 has flown 65 hours with a 10% blend of biofuel and the performance has been very satisfactory
  • A second aircraft, a Dornier, was now undergoing ground tests after it had been cleared by the original manufacturer of the engine, Honeywell, for use of 50% biofuel.
  • The global aviation industry is one of the biggest emitter of greenhouse gases that cause global warming. The fuel consumption of the IAF for 2021-22 was 6.2 lakh kilo litres, which contributed 15 lakh tonnes of carbon dioxide.
  • Airbus said it had plans to offer 100% sustainable aviation fuel (SAF) compatibility on its commercial aircraft latest by 2030.
  • Indian Air Force’s (IAF’s) AN-32 aircraft was formally fleet certified to fly on blended aviation fuel containing up to 10% of indigenous bio-jet fuel.
  • The indigenous bio-jet fuel was first produced by the CSIR-IIP lab at Dehradun in 2013, but could not be tested or certified for commercial use on aircraft due to lack of test facilities in the civil aviation sector.
  • In July, 2018, Chief of the Air Staff Air formally announced IAF’s intention to permit the use of all its resources for testing and certifying the indigenous fuel.
  • This fuel is made from Jatropha oil sourced from Chattisgarh Biodiesel Development Authority (CBDA) and then processed at CSIR-IIP, Dehradun.
