Environmental Impact
Traditional jet fuels, derived from fossil fuels, release substantial amounts of carbon dioxide (CO2), nitrogen oxides (NOx), and sulfur oxides (SOx) into the atmosphere. These emissions contribute to climate change and air pollution, resulting in adverse health effects. The aviation industry is responsible for approximately 2-3 percent of global CO2 emissions and will rise further. To mitigate these detrimental effects, transitioning to sustainable aviation fuels is crucial.
Glocal Inference
Understanding Sustainable Aviation Fuels
Sustainable aviation fuels are derived from renewable resources such as sugary and starchy feedstocks, waste oils, and agricultural and forestry residues. SAFs offer a promising solution by significantly reducing carbon emissions and minimising the environmental impact. They are designed to be drop-in replacements for conventional jet fuels, requiring no modifications to aircraft. SAFs offer a range of benefits, including improved air quality and increased energy security.
Mitigating Environmental Impact
The International Air Transport Association (IATA) agrees that using sustainable aviation fuels and carbon offsetting will contribute more than 80 percent of the reduction in GHG emissions. By utilising sustainable feedstocks and advanced refining processes, SAFs can be produced with minimal life cycle emissions. These fuels can also act as a carbon sink, effectively removing CO2 from the atmosphere during their production process.
Fostering Technological Advancements
A Perfect Ecosystem
During the 41st assembly, International Civil Aviation Organisation (ICAO) announced the Long-Term Aspirational Goal (LTAG) to achieve Net-Zero by 2050. The expected SAF requirement is around 449 billion litres (350 million tons) per year to achieve this goal. Carbon Offsetting & Reduction Scheme in International Aviation (CORSIA) established by ICAO has created policies and market drivers to trigger demand to produce SAF. At COP26 Glasgow Summit, Prime Minister Narendra Modi announced that the nation will achieve NetZero by 2070. It was a watershed moment in India’s fight against climate change and will help reduce emissions by around 20 million tonnes annually.Governments have started implementing measures such as tax incentives, blending mandates, and research grants to promote the use and production of SAFs. Collaboration between airlines, airports, and fuel suppliers is crucial to establish robust supply chains and distribution networks. Constructive policymakers, adaptive industries, and conducive markets are willing to embrace sustainable alternatives.
Socio-Economic-Environmental Impact
Traditional jet fuels are derived from fossil fuels, which are finite resources and subject to price volatility. SAF contributes to a stable and resilient energy supply chain, mitigating the risks associated with geopolitical tensions and fluctuating oil prices. As the demand for SAF increases, it will drive investment in research, infrastructure, and manufacturing facilities, increasing employment opportunities. The production of around 360,000 tons of SAF per year will positively impact India’s GDP by approximately $2.8 billion. This would result in additional income for farmers, enhanced energy security, boosting the rural economy, efficient waste management, and cleaner skies.
