A solution for the carbon impact of flying
Which of you really need to go on vacation abroad? Or is there someone whose work is hampered because of the pandemic in 2020? Yes, the need for aviation is very vital for the world community today. But has anyone ever realized how much the carbon impact of flying?
Now we will examine the environmental impact of aviation. The goal is to innovate every human activity so that it is more in harmony with nature while still being able to drive the economy well.

How bad is air travel for the environment?
According to the International Air Transport Association (IATA) the aviation sector contributes 2% of global carbon emissions. These emissions are expected to decrease due to the pandemic. However, when this pandemic is over, the need for air transportation is expected to increase dramatically, especially for holidays.
The Intergovernmental Panel On Climate Change (IPCC) once predicted that CO2 emissions in 2050 will increase 2-5 times. China's Civil Aviation also related that increasing aviation revenue is always related to increasing carbon emissions.

How much carbon does a flight produce?
Avtur and kerosine fuels produce CO2, Chi, NOx, CO and SO2 emissions. CO2 compounds, CO can trigger global warming, while SO2 can trigger acidification. Meanwhile, NOx gas can destroy ozone. The avtur emission factor is the same as fuel oil in general.
Kerosene also produces CO2 emissions like aviation fuel and CH4 has a global warming effect greater than CO2. According to data from the IPCC, the emission value or emission factor of CH4 is 28 times greater than that of CO2
How can we reduce our carbon footprint when flying?
The most common way for airlines to reduce environmental impact is the existence of environmental funds in airplane tickets. The funds are then included in CSR.
In addition, Xiao Liu from Huaiyin Normal University wrote in his journal entitled flying into the future, saying that the solution to reducing carbon emissions is to promote the use of renewable energy and reduce the growth rate of air transportation.
Lowering the growth rate of air transportation is certainly not a wise choice for all levels of society. In addition to the high cost and high capital needs of the aviation industry, the need for people to move places is also increasing and cannot be stopped.
The best solution at this time is the use of sustainable aviation fuel (SAF). The use of SAF fuel will focus on the use of biomass. This of course requires cooperation between the providers of cooperation, namely farmers, bio-refinery processors, airlines, and policy makers.
Policy Maker has made regulations in the form of a Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) to spur a reduction in the carbon footprint of the aviation sector. This step will be fulfilled by using SAF on an international scale.
According to research from Hsun Chao etc. The study results show that implementing a CORSIA-type policy can stimulate SAF demand and reduce emissions while maximizing the profitability of airlines. Therefore, these policies can contribute to reducing carbon emissions.
The use of biomass-based fuels will certainly reduce carbon emissions because they have a smaller emission factor than fossil fuels. The International Air Transport Association (IATA) is optimistic that it can reduce carbon emissions by 50% in 2050 compared to 2005.
The request for SAF was first made by Oslo airport as a blended fuel starting in 2016 to reduce the carbon impact of flying. The move was followed by Los Angels (LAX) and Stockholm (ARN) airports. The United Airlines has collaborated with Boston-base World Energy to order 10 million gallons of SAF at in 2019.
