Your Journey's Impact on Earth's Environment
In the post-pandemic era, travel choices are under the spotlight, particularly when it comes to air transportation. As the world gears up to resume travel, it's crucial to consider the impact of air travel on our planet and explore ways to reduce its carbon footprint.
One key factor to consider is the longevity of carbon dioxide (CO2) emitted from air travel. Contrary to popular belief, CO2 remains in the atmosphere for thousands of years, making it a significant contributor to climate change. In 2013, global CO2 emissions from commercial aviation were 710 million tons. By 2018, this number had increased to 905 million tons, a 28.5% increase in just five years [1].
The good news is that there are ways to mitigate the carbon footprint of air travel. One such method is offsetting flights with companies like Plant:Grove. Another approach is to focus on the use and support of Sustainable Aviation Fuels (SAF).
SAF, made from renewable feedstocks like waste oils and organic waste, can reduce lifecycle carbon emissions by up to 80% compared to conventional fossil jet fuel. Although SAF currently represents a small share (~0.7%) of global aviation fuel use, it is considered the most viable near-term solution to decarbonize aviation [2]. The EU and UK are already mandating minimum SAF blends starting at 2% in 2025, rising to around 70% by 2050 [2].
To fly more sustainably, prioritizing flights that incorporate SAF is essential. Additionally, choosing airlines or routes that use SAF or are committed to green targets can make a significant difference. Some European airports and airlines are advancing infrastructure and operations toward net zero by 2030 [3].
Minimizing unnecessary flights, especially short-haul flights where alternatives like trains exist, is another effective strategy. Although alternatives like restricting short-haul flights have limited overall impact compared to SAF, minimizing total flight distance reduces fuel use and emissions per trip [2].
Supporting innovation and market mechanisms is equally important. Encouraging policies like the EU Emissions Trading System and investments into hydrogen and battery-electric aircraft may aid longer-term decarbonization [3].
Currently, SAF remains expensive and supply-constrained, so the transition is gradual and requires policy support and industry commitment. However, prioritizing flights that incorporate SAF and supporting initiatives toward greener aviation represent the most effective air travel choices to reduce carbon footprints at present [1][2][3].
In conclusion, choosing airlines and flights that use or promote Sustainable Aviation Fuel, minimizing unnecessary flights, especially short-haul where alternatives exist, and supporting broader clean aviation initiatives constitute the best steps to fly more sustainably today. By making informed choices, we can collectively contribute to a greener future for air travel.

Environmental science highlights the significant impact of air travel on climate change, particularly due to the longevity of carbon dioxide (CO2) emitted from airplanes. Contrary to popular belief, CO2 remains in the atmosphere for thousands of years, making it a substantial contributor to climate change.
In the post-pandemic era, when travel is under scrutiny, it's essential to prioritize ethical travel choices that minimize carbon footprint. One approach is to support the use of Sustainable Aviation Fuels (SAF), made from renewable feedstocks, which can reduce lifecycle carbon emissions by up to 80%.
By choosing airlines or routes that incorporate SAF or are committed to green targets, travelers can contribute to a greener future for air travel.

Furthermore, supporting innovation and market mechanisms, such as investing in hydrogen and battery-electric aircraft or encouraging policies like the EU Emissions Trading System, can aid longer-term decarbonization in the aviation sector.
