Figure 2.

Boxplot of the WTWa climate impact of different fuels analyzed for the B788 aircraft at a 3500 nm stage length. (A) WTWa impact, kg CO₂-eq per 1000 pax-nm. (B) Percent difference of alternative fuels from conventional fuels, where a negative value indicates a reduction. The β values along the bottom represent the likelihood that the alternative fuel is less impactful than the conventional fuel. Sorted by fuel type and median value. Colors reflect the fuel pathway. Extreme outliers not shown.
