Altitude-dependent climate impacts and economic feasibility of alternative fuels in aviation from 2025 to 2050.
Article in iScience, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The aviation industry plays an increasing role in climate change due to emissions at cruise altitudes. This study combines projections from the Aviation Integrated Model (AIM) and simulations from the Aviation-FAIR model to assess greenhouse gas concentrations, radiative forcing, and temperature effects across emission altitudes from 500 to 40,500 ft during 2025-2050. The results reveal that climate impact intensifies with altitude and peaks at 34,500 ft. In addition, a cost-benefit analysis evaluates the use of sustainable aviation fuel (SAF) and hydrogen energy in civil aviation. By 2050, offsetting the costs of these fuels will require $354.44 billion for SAF and $1,888.44 billion for hydrogen. This study assesses the altitude-dependent climate effects of aircraft emissions and the economic feasibility of alternative aviation energy technologies, highlighting both their mitigation potential and cost-related limitations.
