Aviation contribute 12% of CO2 emissions from all mode of transportation, in comparison to the 74% contribution from road transportation. The global aviation industry produces >900 million tons of CO2, constitutes about 2% of all human-induced CO2 emissions.



It may appear relatively small compare to other sources, but it is a fast-growing, fossil fuel-intensive transportation mode –fuel typically accounts for 20% to 30% of operational cost.

The industry is facing the challenge of reducing its environmental footprint in line with international goals to reach net-zero emissions by 2050. With measures such as; the increase of operational fuel efficiency, aircraft technology improvement, decrease the dependence on traditional hydrocarbon fossil fuel, and CORSIA/Carbon offsetting & Reduction Scheme for International Aviation –subject for another post(?)

On 6 October 2021, PT Pertamina (Persero) and Institut Teknologi Bandung have successfully completed a flight test, operating a CN-235 aircraft of PT Dirgantara Indonesia (Indonesian Aerospace), fueled by Palm oil based BioAvtur J2.4 for the Right engine and the regular Jet A1 for the Left engine. The CN-235 Flying Test Bed flown from Bandung to Jakarta. Following the previous series of technical tests up to this flight test, including in-flight engine restarting test. The result was satisfactory with both engine shows nil significant differences in the performance.

Biofuel/bioavtur reduces emissions by up to 80% versus fossil fuel. But it cost more, in US it’s up to 4 times of conventional fossil fuel. Homework on the business case need to be done for Industry scale use of this bioavtur.

The milestone worth cheering, to meet the targeted utilization of Bioavtur 3% by 2020, and 5% by 2025 for the Air Transport, per Ministry of Energy and Mineral Resources (ESDM) mandates, inline with Ministry of Transportation Republic Indonesia roadmap. Backed by policies toward the sustainability of the biofuel feedstock. As part of government self-appointed targets for the reduction of greenhouse gas emissions in response to climate change.


I’d love to hear your thoughts.
