Clean Fuel: Jet Fuel | Climate Now Ep. 2.2

Aviation is makes up 2.5% of global #greenhousegasemissions, though this figure is expected to grow as developing parts of the world become wealthier and increase demand for air travel. Experts have looked to #sustainableaviationfuel (SAF) to decrease emissions as it can be used with existing jet engines and decrease CO2 emissions by 60-80% - moving toward 100% - and potentially become a #negativeemissionstechnology.

Using conventional aviation fuel, a roundtrip flight from New York to Los Angeles generates 2 metric tons of carbon dioxide on a typical airline. That’s the same as driving a passenger car more than 5,000 miles. Jetting from Denver to Paris generates 5 metric tons of CO2. While Miami to Shanghai puts out nearly 10 tons of carbon dioxide. This chart shows how much carbon dioxide and other greenhouse gases are generated by air travel as compared to other forms of transportation on a passenger per kilometer basis. In this video, we’ll take a look at how SAF is produced and some of the obstacles for companies hoping to capitalize on the demand for green jet fuel. The path to commercialization takes several years, and it’s only now arriving for a handful of SAF producers. The demand will likely grow as policymakers in Europe and the US consider new requirements for the use of sustainable aviation fuels. Although carbon emissions from jet travel make up only 2.5% of global greenhouse gases, experts worry that as the demand for air travel grows in developing parts of the world, so too will that figure. In addition to carbon dioxide, jet engines also produce additional sulfur and nitrogen pollutants, water vapor and contrails. These compounds amplify the overall contribution of jet travel to climate warming to an estimated 7-8% of global emissions. According to projections from the International Civil Aviation Organization, carbon emissions from the aviation sector are projected to double by 2050. The United States is the biggest polluter, according to the International Council on Clean Transportation, but China is catching up quickly. For context, the US’s 179 million metric tons is approximately 2% of total US emissions. For the EU and China the percentage is similar. But sustainable aviation fuel might allow commercial aircraft to keep flying while mitigating their overall environmental impact. Aviation industry studies show SAF can reduce CO2 emissions by 60 to 80% moving towards 100% and potentially become a negative emission technology through supply optimization, use of biofuels for transport, use of green hydrogen for the fuel processing, and carbon sequestration.
