Assessment of the Value of Large-Scale Use of Sustainable Aviation Fuels for Global Flights in 2050

Abstract

By analyzing the projected data for the year 2050, it will be determined whether it is worthwhile to fully replace regular jet fuel with sustainable jet fuel in the future, based on the cost and efficiency in reducing carbon emissions. Although SAF still has many drawbacks at this stage (e.g., relatively low conversion efficiency, high cost, etc.), its reduction in carbon emissions should not be overlooked, and thus the full-scale use of SAF is still a topic for discussion. Therefore, this paper focuses on the impacts and harms of carbon emissions as well as the advantages and disadvantages of SAFs, while comparing and estimating the situation at this stage using various data projections for 2050 provided by a number of organizations and companies. The data points out that the biggest problems with SAFs are cost and trust. The real reason for the high cost is the loss of resources in the conversion of raw materials to kerosene due to the lack of technology, which in turn requires the consumption of more materials to make up for this shortcoming, and the issue of trust in SAFs arises from this. However, the core of the problem is quite simple. If it is just a matter of technology, then given the rapid advancement of technology, one day we will be able to solve it. Therefore, the full use of SAF is necessary because it will significantly reduce carbon emissions, pollution, and global warming. It will also contribute greatly to the environmental protection of mankind.
