Air travel accounts for about 12 percent of greenhouse gas emissions from the transport industry—or at least it did before the pandemic. It is likely that once again travel will account for a solid portion of emissions once the industry recovers. Now, a team of scientists has found a way to reverse some of the damage by making jet fuel from carbon dioxide. Air transport generated 915 million tons of carbon dioxide in 2019, according to data from the Air Transport Action Group, a Swiss-based industry organization. This represented some 2 percent of total human CO2 emissions that year, which may be a small number in terms of percentages but still a substantial amount of emitted CO2. And this CO2 could be out to good use. The Oxford University team used a process called organic combustion to break down the carbon dioxide molecule into its constituents and convert these […]
